- FIG. 7 a is a schematic representation of a lumbar muscle exercise system being used in accordance with the present invention. Specifically, a first member 32 firmly supports lower pelvic portion 34 of a user 36 leaning against first member 32 . A second adjoining member 38 firmly supports feet 40 of user 36 away from first support member 32 with the user's lower limbs 42 being held substantially straight. A pelvic movement restraint 44 , of the type generally described hereinabove, is nestled between first support member 32 and upper pelvic portion 46 of user 36 effectively locking hip joint 48 .
- Pelvis 50 incorporates the socket portion of hip joint 48 for each lower limb of user 36 .
- first and second support members 32 , 38 may be implemented as the wall and floor of a room, respectively, with user 36 leaning back against the wall, as generally illustrated in reference to FIG. 7 a .

- Hip joint 48 is the ball-and-socket joint comprising the articulation between femur 49 ( FIGS. 7 a , 8 a - 8 c ) and the hip bone of user 36 .
- the hip bone is the large flaring bone that makes a lateral half of pelvis 50 ( FIG. 7 a ) of user 36 .
- the hip bone is composed of ilium 52 ( FIGS. 8 b - 8 c ), ischium 54 ( FIGS. 8 b - 8 c ) and pubis (not shown) of user 36 . These bones are consolidated into one bone in the adult which is also known as the pelvic or innominate bone.
- pelvis 50 ( FIG. 8 a ) is illustrated and described herein as comprising upper pelvic portion 46 ( FIG. 8 b ) and lower pelvic portion 34 ( FIG. 8 b ).
- Upper pelvic portion 46 includes ilium 52 and sacrum 51 , as schematically depicted in FIG. 8 b .
- the sacrum consists of five vertebrae fused together. It articulates on each side with the ilium bones forming the sacrolitic joints. Sacrum 51 is connected to the lumbar portion of spine 53 ( FIG. 8 a ) of user 36 , as schematically shown in FIGS. 8 b - 8 c .
- Lower pelvic portion 34 includes ischium or so-called “sit” bones 54 ( FIGS. 8 a - 8 c ).

- the gluteus muscles comprise the three large muscles (gluteus maximus, gluteus maxims and gluteus minimus) of each buttock that extend, abduct and rotate the thigh.
- the hamstring muscles act across both the hip and knee joints producing extension and flexion, respectively.
- the medial hamstring contributes to medial rotation of the leg at the flexed knee joint, while the lateral hamstring contributes to lateral rotation.
- the gluteus and hamstring muscles 37 , 39 pull pelvis 50 ( FIG. 7 a ) back around the top of the thighs at the hip joints 48 ( FIG. 7 a ), such as when user 36 stands up from leaning forwards.
- the gluteus and hamstring muscles 37 , 39 do not bend spine 53 ( FIG. 8 b ) of user 36 ( FIG. 7 a ).
- Lumbar muscles 35 can extend spine 53 backwards. However, for the most part, lumbar muscles 35 just hold the user's torso 41 ( FIG. 8 a ) steady while the gluteus and hamstring muscles 37 , 39 ( FIG. 9 ) pull pelvis 50 ( FIG.

- FIGS. 10 a - 10 c schematically illustrate a series of steps performed by an individual in preparation for using lumbar muscle exercise system 22 in accordance with the general principles of the present invention.
- the first step may involve a user 80 standing with his back against a vertical support member 82 , such as a wall or the like, as schematically depicted in FIG. 10 a .
- the next steps may involve user 80 stepping forward, and then leaning back against vertical support member 82 with his feet 84 a comfortable width apart and lower limbs 86 held as straight as comfortable and firm, as schematically shown in FIG. 10 b .
- Care should be taken to ensure that feet 84 do not slide on horizontal support member 88 , such as the floor of a room or the like.
- Care should also be taken to prevent vertical and/or horizontal support members 82 , 88 , respectively, from moving when user 80 utilizes the same for support. For example, user 80 should not lean on a door which opens away from him.
- the user's buttocks 90 ( FIG. 10 b ) should be resting on vertical support member 82 at all times. Thereafter, user 80 rotates his pelvis forward as far as anatomically possible while keeping lower limbs 86 firm. As schematically illustrated in FIG. 10 c , user 80 may use his hands 92 to push back against vertical support member (wall) 82 , as needed. User 80 should be able to feel his ischium (“sit” bones) pressing against vertical support member (wall) 82 . Ischium or “sit” bones are schematically shown, for example, in reference to FIGS. 8 a - 8 c under reference numeral 54 .
- FIG. 11 a schematically shows a user 100 pressing his ischium or “sit” bones against vertical support member (wall) 102 with a pelvic movement restraint 104 (which is of the type generally shown and described hereinabove in reference to FIGS. 1-6 b ) disposed nearby on an adjoining horizontal support member (floor) 106 .
- pelvic movement restraint 104 which is of the type generally shown and described hereinabove in reference to FIGS. 1-6 b
- FIG. 11 b user 100 has rolled pelvic movement restraint 104 down his sacrum nestling it into place to make as much contact as possible with both the sacrum and wall 102 without in any way moving buttocks 103 away from wall 102 . This is to prevent the user's pelvis from rotating backwards (toward wall 102 ) during exercise.
- pelvic movement gauges 108 which are of the type generally shown and described hereinabove in reference to FIGS. 3-4 , 6 a - 6 b ) between his “sit” bones and wall 102 . Insertion of pelvic movement gauges 108 against a vertical transparent wall 101 is schematically shown in FIG. 14 a . Each pelvic movement gauge is disposed such that it sticks out to a certain extent sideways with user 100 firmly pressing the same against wall 102 via his “sit” bones.
- FIG. 11 d user 100 has extended his torso 112 upward (away from feet 122 ) as far as anatomically possible against gravity G, as generally shown by directional arrow 105 , with pelvic movement gauges 108 being firmly held in place against wall 102 .
- FIG. 11 c torso 112 is shown flexed in the opposite direction (toward feet 122 ) as far as anatomically possible, as generally shown by directional arrow 107 , with pelvic movement gauges 108 being firmly held in place against wall 102 .
- FIGS. 11 d - 11 c may be repeated as part of an exercise routine to strengthen the lumbar muscles of user 100 .
- user 100 moves slowly from position A ( FIG. 11 c ) to position B ( FIG. 11 d ), back to position A, and again to position B smoothly and without stopping until no further movement (torso extension/flexion) is possible, or until user 100 feels some discomfort.
- Normal physical discomfort associated with exercises of such kind, and an almost uncontrollable urge to discontinue while movement is still possible is to be expected and ignored.
- Movement should continue at a relatively slow and steady pace, pausing only in the top (B) position to ensure full control, until user 100 is unable to continue due to muscular fatigue of the lumbar muscles.
- the entire routine should take between one (1) to two (2) minutes in most cases, but could be sooner or longer in duration depending on individual user(s). It is important not to pause in order to perform another repetition, but to continue slowly, and then discontinue the exercise when movement (torso extension/flexion) slows down to a stop.
- the angular range of motion (torso extension/flexion) varies with users. For the average user, the angular range of motion is estimated to be approximately 72° (angle ⁇ -angle ⁇ ), as schematically depicted in FIG. 7 a.
- user 100 may practice extending torso 112 upward (away from feet 122 ) as far as anatomically possible before one or both pelvic movement gauges 108 slide(s) down and then fall(s).
- User 100 should get used to the feeling of pushing his “sit” bones back into gauges 108 .
- User 100 should also avoid at all costs pushing back into pelvic movement restraint 104 instead.
- User 100 should push into floor 106 through the front of his feet, not his heels. The base of the big toes would be an acceptable spot to focus on pushing through. If done correctly, pelvic movement gauges 108 will remain in place letting the user know that he is exercising properly his lumbar muscles.
- pelvic movement restraint 104 remains stable in its adherence to both the user's sacrum and wall 102 without rolling up and down, feet 122 do not move, wall 102 and floor 106 remain stationary, and pelvic movement gauges 108 (held in place by the user's “sit” bones) remain in place, then it would be safe to assume that the pelvis has not rotated around the hip sockets. Therefore, the gluteus and hamstring muscles have not contributed to the torso extension/flexion routine as performed in reference to FIGS. 11 c - 11 d , 14 b - 14 c.
- user 100 may try deliberately to extend torso 112 ( FIG. 11 d ) upwards (away from feet 122 ) too far as if trying to stand up too straight while pushing back into pelvic movement restraint 104 . In such case, user 100 will observe that gauges 108 slide down and fall to floor 106 . This shows that pelvic movement around the hip joints has occurred, which is what user 100 has to avoid.
- User 100 may increase the resistance during a lumbar muscle exercise routine performed in accordance with the general principles of the present invention by folding his arms in front of the torso, as generally illustrated in FIGS. 12-13 .
- the hands could be held above the head to increase the difficulty of the lumbar muscle strengthening exercise (not shown).
- All lumbar muscle strengthening exercises should be performed slowly and under full control with no fast movement of any kind. Greater exercise speed generally implies greater force, and greater force increases the likelihood of injury.
- Lumbar muscle exercise routines are supposed to strengthen the user's muscles to prevent or heal injury, not cause it.
- FIGS. 15 a - 15 b schematically illustrate a user 130 using lumbar muscle exercise system 131 (which is of the type generally shown and described hereinabove in reference to FIGS. 1-6 b ) in conjunction with added resistance in the form of weights 132 held by user's hands 134 .
- Other suitable forms of increased/added resistance may be utilized, as needed.
- FIG. 15 b user 100 has extended torso 135 upward (away from feet 138 ) against gravity G, as generally shown by directional arrow 137 , with the pelvic movement gauges of muscle exercise system 131 being firmly held in place against wall 133 .
- torso 135 is shown flexed in the opposite direction (toward feet 138 ), as generally shown by directional arrow 139 , with the pelvic movement gauges of muscle exercise system 131 still being held in place against wall 133 in accordance with the present invention.
- FIGS. 16 a - 16 h schematically depict a simplified physical model for use in understanding the general principles of the present invention.

- Lever 200 is pivotally coupled to lever 202 via a fulcrum 206
- lever 204 is pivotally coupled to lever 202 via a fulcrum 208 .
- Fulcrum 208 is disposed at a lower elevation relative to fulcrum 206 in accordance with anatomical requirements.

- FIGS. 16 f - 16 g the user's buttocks are schematically shown leaning against a vertical support member 210 .
- an obstacle 212 has been wedged between vertical support member 210 and the pelvis (lever 202 ) to keep the top of the pelvis (upper pelvic portion) from moving backwards (toward vertical support member 210 ) while the user pushes the bottom of the pelvis (lower pelvic portion) into vertical support member 210 , thus immobilizing the pelvis.
- the torso may be pivotally lifted and lowered via fulcrum 206 relative to feet 205 to effectively target the lumbar muscles.

- the pelvic restraint is lightweight, compact and easy to handle. It is made to provide comfort and safety while also giving users the required degree of resistance and grip to make it truly effective.
Abstract
A lumbar muscle exercise system comprises a first member which supports the lower pelvic portion of a user. The user is leaning against the first member. A second adjoining member supports the feet of the user away from the first member. The lower limbs of the user are held substantially straight. A pelvic restraint prevents the upper pelvic portion from moving toward the first support member while the lower pelvic portion is firmly pressed into the first support member. The leaning user extends the torso away from the feet against gravity as part of a targeted lumbar muscle exercise routine. At least one gauge indicates undesirable movement of the lower pelvic portion relative to the first support member while the user performs the lumbar muscle exercise routine.
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/622,988, filed on Oct. 29, 2004, which is incorporated herein in its entirety by reference.
- Portions of the disclosure of this patent document may contain material that is subject to copyright and/or mask work protection. The copyright and/or mask work owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as it appears in the Patent and Trademark Office patent file or records, but otherwise reserves all copyright and/or mask work rights whatsoever.
- In recent years, physicians and fitness professionals have discovered that many back problems are related to the spinal extensor (lumbar) muscles being tight and weak. The spinal extensor muscles generally reduce translational stress to the intervertebral segments during activity and balance shear stress to the intervertebral segments.
- It has also been discovered that if the lumbar muscles are properly exercised to become stronger, a lot of back pain diminishes or goes away entirely. To properly stimulate the lumbar muscles with exercise, these muscles must be bending the spine backwards against resistance with the gluteus and hamstring muscles not moving the pelvis relative to the thighs at the same time. If the spine is bending, and at the same time, the hips are moving, then the lumbar muscles, and the gluteus and hamstring muscles are all working together. In such case, the lumbar muscles will not be optimally stimulated, and subsequently optimally strengthened as part of an exercise routine.
- A properly performed lumbar muscle exercise routine will be of benefit to anybody who wants to avoid or improve lower back problems, anyone who wants to do their bit to prevent injury to this critical area, anybody who hopes to enjoy a physically active life, as well as those in sedentary jobs who want to remain functional in their lumbar region, i.e. most people. A number of known exercises do not effectively strengthen the lower back muscles because such exercises normally do not lock the hip joints. Sophisticated clinical machines on the market are capable of effectively targeting the lumbar muscle group. However, such machines require trained operation and are out of reach to the average user who is using the local gym. Local gyms are normally not equipped with such complex and expensive exercise machines.
- Exemplary embodiments disclosed herein are generally directed to a lumbar muscle exercise system.
- In accordance with one aspect of the invention, the lumbar muscle exercise system comprises a first member adapted to support the lower pelvic portion of a user leaning against the first member, and a second adjoining member adapted to support the feet of the user away from the first member. The lower limbs of the user are held substantially straight. The muscle exercise system also comprises means for preventing the upper pelvic portion of the user from moving toward the first member while the lower pelvic portion is firmly pressed into the first member. The preventing means allows the leaning user to extend the torso away from the feet against gravity as part of a targeted lumbar muscle exercise routine.
- In accordance with another aspect of the invention, the lumbar muscle exercise system comprises a first member adapted to support the lower pelvic portion of a user leaning against the first member, and a second adjoining member adapted to support the feet of the user away from the first member. The lower limbs of the user are held substantially straight. The muscle exercise system also comprises means for preventing the upper pelvic portion of the user from moving toward the first member while the lower pelvic portion is firmly pressed into the first member. The preventing means allows the leaning user to extend the torso away from the feet against gravity as part of a targeted lumbar muscle exercise routine. The muscle exercise system further comprises means for indicating undesirable movement of the lower pelvic portion relative to the first member while the user performs the lumbar muscle exercise routine.

The description sets forth the functions and the sequence of steps for constructing and operating the exemplary embodiments in connection with the illustrated embodiments. However, it is to be understood that the same or equivalent functions and sequences may be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of the present invention.
- Some embodiments of the present invention will be described in detail with reference to an exercise system designed to target and strengthen the lumbar muscles of a user, as generally shown in
FIGS. 1-26 . Additional embodiments, features and/or advantages of the invention will become apparent from the ensuing description or may be learned by practicing the invention. In the figures, the drawings are not to scale with like numerals referring to like features throughout both the drawings and the description. -
FIG. 1 is a side perspective view of apelvic movement restraint 20 of a lumbar muscle exercise system 22 (FIG. 3 ) in accordance with the present invention. In one exemplary embodiment,pelvic movement restraint 20 has a solid generally bullet-shaped body made of lightweight rigid material such as foam and the like. Alternatively, the pelvic movement restraint of the present invention may have a substantially tubular body that is closed at each end and filled with air, as generally shown inFIG. 26 . In other exemplary embodiments, the pelvic movement restraint may have alternative shapes, as generally depicted in reference toFIGS. 17-25 , and/or be constructed from different material(s). Other suitable variations in shape and material(s) may be utilized for the pelvic movement restraint of the present invention, as needed. -
Pelvic movement restraint 20 may be provided with aremovable grip cover 24, as generally depicted inFIG. 2 .Grip cover 24 may be constructed from a strip of relatively non-slip textured soft resilient material such as synthetic rubber or the like. The soft resilient strip may be rolled onto the exterior surface ofpelvic movement restraint 20 and secured thereon with adhesive or the like. Alternatively, grip cover 24 may be integrally formed on the exterior surface ofpelvic movement restraint 20. In the exemplary embodiment shown inFIG. 2 ,removable grip cover 24 extends over a substantial portion of the exterior surface ofpelvic movement restraint 20. Other variations on grip cover surface coverage ofpelvic movement restraint 20 may be utilized, as needed. - One end of
pelvic movement restraint 20 is cut away internally to a certain extent to create a cavity 26 (FIG. 3 ). The interior surface ofcavity 26 includes a generally X-shaped body cut 27 (FIG. 5 ) which is adapted to receive a pair of pelvic movement gauges 28, 30 (FIGS. 3-4 , 6 a-6 b) in accordance with the present invention. Pelvic movement gauges 28, 30 may be completely inserted within the body of pelvic restraint 20 (via body cut 27) for storage (FIG. 4 ) wheneverpelvic restraint 20 is not being used in a lumbar muscle strengthening exercise routine. Each pelvic movement gauge (28, 30) is shaped somewhat like a glider plane that is missing its wings (FIGS. 6 a-6 b). Each pelvic movement gauge (28, 30) may be easily constructed from a generally flat plastic strip or the like. Other shape and material configurations may be used, as needed. -
FIG. 7 a is a schematic representation of a lumbar muscle exercise system being used in accordance with the present invention. Specifically, afirst member 32 firmly supports lowerpelvic portion 34 of auser 36 leaning againstfirst member 32. A second adjoiningmember 38 firmly supportsfeet 40 ofuser 36 away fromfirst support member 32 with the user'slower limbs 42 being held substantially straight. Apelvic movement restraint 44, of the type generally described hereinabove, is nestled betweenfirst support member 32 and upperpelvic portion 46 ofuser 36 effectively lockinghip joint 48.Pelvis 50 incorporates the socket portion of hip joint 48 for each lower limb ofuser 36. - A person skilled in the art would readily appreciate that a locked hip joint 48 would prevent
pelvis 50 from rotating back towardfirst support member 32 as long as lowerpelvic portion 34 remains firmly pressed intofirst support member 32. In one embodiment, first andsecond support members user 36 leaning back against the wall, as generally illustrated in reference toFIG. 7 a. Other suitable implementations of first andsecond support members - Hip joint 48 is the ball-and-socket joint comprising the articulation between femur 49 (
FIGS. 7 a, 8 a-8 c) and the hip bone ofuser 36. The hip bone is the large flaring bone that makes a lateral half of pelvis 50 (FIG. 7 a) ofuser 36. The hip bone is composed of ilium 52 (FIGS. 8 b-8 c), ischium 54 (FIGS. 8 b-8 c) and pubis (not shown) ofuser 36. These bones are consolidated into one bone in the adult which is also known as the pelvic or innominate bone. - For purposes of describing the general principles of the present invention, pelvis 50 (
FIG. 8 a) is illustrated and described herein as comprising upper pelvic portion 46 (FIG. 8 b) and lower pelvic portion 34 (FIG. 8 b). Upperpelvic portion 46 includesilium 52 andsacrum 51, as schematically depicted inFIG. 8 b. The sacrum consists of five vertebrae fused together. It articulates on each side with the ilium bones forming the sacrolitic joints.Sacrum 51 is connected to the lumbar portion of spine 53 (FIG. 8 a) ofuser 36, as schematically shown inFIGS. 8 b-8 c. Lowerpelvic portion 34 includes ischium or so-called “sit” bones 54 (FIGS. 8 a-8 c). - To strengthen his/her lumbar muscles 35 (
FIG. 9 ),user 36 may exercise the same by extending spine 53 (FIGS. 8 b-8 c) backwards (toward first support member 32) against resistance, such as gravity, without the gluteus andhamstring muscles 37, 39 (FIG. 9 ) helping out. The gluteus muscles comprise the three large muscles (gluteus maximus, gluteus medius and gluteus minimus) of each buttock that extend, abduct and rotate the thigh. The hamstring muscles act across both the hip and knee joints producing extension and flexion, respectively. The medial hamstring contributes to medial rotation of the leg at the flexed knee joint, while the lateral hamstring contributes to lateral rotation. - The gluteus and
hamstring muscles 37, 39 (FIG. 9 ) pull pelvis 50 (FIG. 7 a) back around the top of the thighs at the hip joints 48 (FIG. 7 a), such as whenuser 36 stands up from leaning forwards. The gluteus andhamstring muscles 37, 39 (FIG. 9 ) do not bend spine 53 (FIG. 8 b) of user 36 (FIG. 7 a). Lumbar muscles 35 (FIG. 9 ) can extendspine 53 backwards. However, for the most part,lumbar muscles 35 just hold the user's torso 41 (FIG. 8 a) steady while the gluteus andhamstring muscles 37, 39 (FIG. 9 ) pull pelvis 50 (FIG. 7 a) up around the hip joints 48 (FIG. 7 a). Sincelumbar muscles 35 are holding torso 41 (FIG. 8 a) generally straight, the gluteus andhamstring muscles entire torso 41 upwards around thehip joints 48 by pulling onpelvis 50. To properly stimulate lumbar muscles 35 (FIG. 9 ) with exercise, the lumbar muscles should be extendingspine 53 backwards (against gravity) with the gluteus andhamstring muscles FIG. 7 a) at the same time. This type of exercise will generally not allow the user to move very far. To be effectively strengthened,lumbar muscles 35 should be exercised in isolation, i.e.user 36 has to lock his/her hip joints 48 (FIG. 7 a). - The nestled pelvic movement restraint (44) allows torso extension against gravity from a first position in which the torso of
user 36 is disposed at a substantially obtuse angle α relative tofirst support member 32 to a second position in which the torso is disposed at a substantially acute angle β relative tofirst support member 32, as generally illustrated inFIG. 7 a. The acute and obtuse angles α, β are generally defined above the hip level of the user (FIG. 7 a). -
FIG. 7 b is a side perspective view of lumbar muscle exercise system 22 (FIG. 3 ) being used in a room setting in accordance with the present invention. Specifically, avertical wall 60 firmly supports lowerpelvic portion 62 of auser 64, while afloor 66 firmly supportsfeet 68 ofuser 64 with the user'slower limbs 70 being held substantially straight. Pelvic movement restraint 20 (FIG. 1 ) with resilient grip cover 24 (FIG. 2 ) is shown nestled betweenvertical wall 60 and upperpelvic portion 72 ofuser 64 so as to lock the user's hip joint (not shown). Pelvic movement gauge 28 (FIG. 6 a) is operatively sandwiched between lower pelvic portion (“sit bones”) 62 ofuser 64 andwall 60 in accordance with the general principles of the present invention, as generally depicted inFIG. 7 b. -
FIGS. 10 a-10 c schematically illustrate a series of steps performed by an individual in preparation for using lumbarmuscle exercise system 22 in accordance with the general principles of the present invention. The first step may involve auser 80 standing with his back against avertical support member 82, such as a wall or the like, as schematically depicted inFIG. 10 a. The next steps may involveuser 80 stepping forward, and then leaning back againstvertical support member 82 with his feet 84 a comfortable width apart andlower limbs 86 held as straight as comfortable and firm, as schematically shown inFIG. 10 b. Care should be taken to ensure thatfeet 84 do not slide onhorizontal support member 88, such as the floor of a room or the like. Care should also be taken to prevent vertical and/orhorizontal support members user 80 utilizes the same for support. For example,user 80 should not lean on a door which opens away from him. - The user's buttocks 90 (
FIG. 10 b) should be resting onvertical support member 82 at all times. Thereafter,user 80 rotates his pelvis forward as far as anatomically possible while keepinglower limbs 86 firm. As schematically illustrated inFIG. 10 c,user 80 may use hishands 92 to push back against vertical support member (wall) 82, as needed.User 80 should be able to feel his ischium (“sit” bones) pressing against vertical support member (wall) 82. Ischium or “sit” bones are schematically shown, for example, in reference toFIGS. 8 a-8 c underreference numeral 54. These bony bumps are generally pointed straight down so thatuser 80 may need to lean forwards (away from vertical support member 82) as far as anatomically possible to make the “sit” bones face backwards, respectively.User 80 may need to bend his knees a bit, starting with buttocks 90 (FIG. 10 c) being a little lower downwall 82 so thatuser 80 can liftbuttocks 90 up out of the way of his “sit” bones since the “sit” bones are disposed anatomically lower than the buttocks. -
FIG. 11 a schematically shows auser 100 pressing his ischium or “sit” bones against vertical support member (wall) 102 with a pelvic movement restraint 104 (which is of the type generally shown and described hereinabove in reference toFIGS. 1-6 b) disposed nearby on an adjoining horizontal support member (floor) 106. InFIG. 11 b,user 100 has rolledpelvic movement restraint 104 down his sacrum nestling it into place to make as much contact as possible with both the sacrum andwall 102 without in anyway moving buttocks 103 away fromwall 102. This is to prevent the user's pelvis from rotating backwards (toward wall 102) during exercise. - In
FIG. 11 c,user 100 has inserted pelvic movement gauges 108 (which are of the type generally shown and described hereinabove in reference toFIGS. 3-4 , 6 a-6 b) between his “sit” bones andwall 102. Insertion of pelvic movement gauges 108 against a verticaltransparent wall 101 is schematically shown inFIG. 14 a. Each pelvic movement gauge is disposed such that it sticks out to a certain extent sideways withuser 100 firmly pressing the same againstwall 102 via his “sit” bones. - In
FIG. 11 d,user 100 has extended historso 112 upward (away from feet 122) as far as anatomically possible against gravity G, as generally shown bydirectional arrow 105, with pelvic movement gauges 108 being firmly held in place againstwall 102. InFIG. 11 c,torso 112 is shown flexed in the opposite direction (toward feet 122) as far as anatomically possible, as generally shown bydirectional arrow 107, with pelvic movement gauges 108 being firmly held in place againstwall 102. - The upward torso extension and downward torso flexion of
FIGS. 11 d-11 c, respectively, may be repeated as part of an exercise routine to strengthen the lumbar muscles ofuser 100. In one exemplary lumbar muscle exercise routine,user 100 moves slowly from position A (FIG. 11 c) to position B (FIG. 11 d), back to position A, and again to position B smoothly and without stopping until no further movement (torso extension/flexion) is possible, or untiluser 100 feels some discomfort. Normal physical discomfort associated with exercises of such kind, and an almost uncontrollable urge to discontinue while movement is still possible is to be expected and ignored. Generally, it should take no less than eight (8) seconds for an average user to move from position A (FIG. 11 c) to position B (FIG. 11 d), hold for a moment, and then move back to position A again. No other pauses should be taken. - Movement (torso extension/flexion) should continue at a relatively slow and steady pace, pausing only in the top (B) position to ensure full control, until
user 100 is unable to continue due to muscular fatigue of the lumbar muscles. The entire routine should take between one (1) to two (2) minutes in most cases, but could be sooner or longer in duration depending on individual user(s). It is important not to pause in order to perform another repetition, but to continue slowly, and then discontinue the exercise when movement (torso extension/flexion) slows down to a stop. The angular range of motion (torso extension/flexion) varies with users. For the average user, the angular range of motion is estimated to be approximately 72° (angle α-angle β), as schematically depicted inFIG. 7 a. - It is also important to keep the legs still and slightly spread throughout the exercise routine, and to keep
buttocks 103 firmly pushed backwards intowall 102, as schematically depicted inFIG. 12 , to prevent pelvic movement gauges 108 (FIGS. 11 c-11 d) from sliding downwall 102. Pelvic movement gauges 108 will remain in place only if the user's buttocks 103 (FIG. 11 c) do not start to lift away fromwall 102 even slightly. Otherwise, one or both pelvic movement gauges 108 may move relative towall 102 and/or fall down onfloor 106 in the manner generally indicated inFIG. 13 . Any observed movement ofgauges 108 is a clear sign touser 100 that his pelvis has rotated relative to the hip joints. Such pelvic rotation should be avoided to allow for correct (targeted) exercise of the user's lumbar muscles. - Once in position A (
FIG. 11 c),user 100 may practice extendingtorso 112 upward (away from feet 122) as far as anatomically possible before one or both pelvic movement gauges 108 slide(s) down and then fall(s).User 100 should get used to the feeling of pushing his “sit” bones back intogauges 108.User 100 should also avoid at all costs pushing back intopelvic movement restraint 104 instead.User 100 should push intofloor 106 through the front of his feet, not his heels. The base of the big toes would be an acceptable spot to focus on pushing through. If done correctly, pelvic movement gauges 108 will remain in place letting the user know that he is exercising properly his lumbar muscles. - In general, if
legs 120 ofuser 100 remain firm and do not move,pelvic movement restraint 104 remains stable in its adherence to both the user's sacrum andwall 102 without rolling up and down,feet 122 do not move,wall 102 andfloor 106 remain stationary, and pelvic movement gauges 108 (held in place by the user's “sit” bones) remain in place, then it would be safe to assume that the pelvis has not rotated around the hip sockets. Therefore, the gluteus and hamstring muscles have not contributed to the torso extension/flexion routine as performed in reference toFIGS. 11 c-11 d, 14 b-14 c. - After some practice,
user 100 may try deliberately to extend torso 112 (FIG. 11 d) upwards (away from feet 122) too far as if trying to stand up too straight while pushing back intopelvic movement restraint 104. In such case,user 100 will observe that gauges 108 slide down and fall tofloor 106. This shows that pelvic movement around the hip joints has occurred, which is whatuser 100 has to avoid. -
User 100 may increase the resistance during a lumbar muscle exercise routine performed in accordance with the general principles of the present invention by folding his arms in front of the torso, as generally illustrated inFIGS. 12-13 . Alternatively, the hands could be held above the head to increase the difficulty of the lumbar muscle strengthening exercise (not shown). All lumbar muscle strengthening exercises should be performed slowly and under full control with no fast movement of any kind. Greater exercise speed generally implies greater force, and greater force increases the likelihood of injury. Lumbar muscle exercise routines are supposed to strengthen the user's muscles to prevent or heal injury, not cause it. -
FIGS. 15 a-15 b schematically illustrate auser 130 using lumbar muscle exercise system 131 (which is of the type generally shown and described hereinabove in reference toFIGS. 1-6 b) in conjunction with added resistance in the form ofweights 132 held by user'shands 134. Other suitable forms of increased/added resistance may be utilized, as needed. - In
FIG. 15 b,user 100 has extendedtorso 135 upward (away from feet 138) against gravity G, as generally shown bydirectional arrow 137, with the pelvic movement gauges ofmuscle exercise system 131 being firmly held in place againstwall 133. InFIG. 15 a,torso 135 is shown flexed in the opposite direction (toward feet 138), as generally shown bydirectional arrow 139, with the pelvic movement gauges ofmuscle exercise system 131 still being held in place againstwall 133 in accordance with the present invention. -
FIGS. 16 a-16 h schematically depict a simplified physical model for use in understanding the general principles of the present invention. Specifically, the body of a user may be modeled as three pivotally coupled levers, whereby the head and torso are represented by alever 200, the pelvis is represented by alever 202, and the lower limbs are represented by alever 204, as schematically shown inFIG. 16 a.Lever 200 is pivotally coupled to lever 202 via afulcrum 206, whilelever 204 is pivotally coupled to lever 202 via afulcrum 208.Fulcrum 208 is disposed at a lower elevation relative to fulcrum 206 in accordance with anatomical requirements.Fulcrum 206 models the pivotal coupling between the lumbar portion of the spine and the pelvis of a user (FIG. 16 b).Fulcrum 208 models the hip joints of the user (FIG. 16 b). - When rotation occurs around
fulcrums FIG. 16 c). To effectively target and strengthen the lumbar muscles, the user should lock the hip joint orfulcrum 208, as schematically illustrated inFIGS. 16 d-16 e. With a locked hip joint (fulcrum 208 being shown schematically with an overlapping crossed circle inFIGS. 16 d-16 g), the lower limbs (lever 204) and pelvis (lever 202) stay fixed. Thus, when the torso (lever 200) is pivotally lifted and lowered viafulcrum 206 relative tofeet 205 of the user, as generally illustrated inFIGS. 16 d-16 e, the spinal extensor (lumbar) muscles are effectively targeted. There is no contribution from the gluteus and hamstring muscles of the user. - In
FIGS. 16 f-16 g, the user's buttocks are schematically shown leaning against avertical support member 210. Moreover, anobstacle 212 has been wedged betweenvertical support member 210 and the pelvis (lever 202) to keep the top of the pelvis (upper pelvic portion) from moving backwards (toward vertical support member 210) while the user pushes the bottom of the pelvis (lower pelvic portion) intovertical support member 210, thus immobilizing the pelvis. With the pelvis immobilized, the torso (lever 200) may be pivotally lifted and lowered viafulcrum 206 relative tofeet 205 to effectively target the lumbar muscles. InFIG. 16 h,obstacle 212 functions, unfortunately, as another fulcrum due to the pelvis (lever 202) pushing back onobstacle 212, rather than back intovertical support member 210. This type of exercise routine would not effectively target the lumbar muscles of the user. -
FIGS. 17-25 show in perspective alternative pelvic movement restraints for use in accordance with the present invention. Specifically, apelvic movement restraint 300 with a substantially rigidtubular body 302 provided with asoft grip cover 304 is generally illustrated inFIG. 17 .Rigid body 302 may be made of polyvinyl chloride (PVC) or other suitable material(s).FIG. 18 shows a generally wedge-shapedpelvic movement restraint 306 having a rounded corner.Pelvic movement restraint 306 may be made of firm material, such as foam or the like.FIG. 19 depicts apelvic movement restraint 308 with asolid body 310 having a substantially semi-circular cross-section.Solid body 310 may be made of firm material.Solid body 310 is provided with asoft grip cover 312. -
FIG. 20 depicts a pelvicmovement restraint body 314 with a cross-section including an acute angle disposed opposite a circular arc. Pelvicmovement restraint body 314 may be constructed from firm material.FIG. 21 shows a generally dumb-bell shapedpelvic movement restraint 316 made of firm material.Pelvic restraint 316 may be provided with a tacky surface texture. For example, spray-on rubber may be applied on the generally cylindricalsurfaces surrounding handle 318.FIG. 22 depicts an alternative dumb-bell shaped pelvic movement restraint 320 made of firm material. Pelvic restraint 320 may be provided with a tacky surface texture. For example, spray-on rubber may be applied on the generally sphericalsurfaces surrounding handle 322. -
FIG. 23 depicts a generally wedge-shapedpelvic movement restraint 324 made of firm material.Pelvic restraint 324 may be provided with a tacky surface texture. For example, spray-on rubber may be applied on its outer surface.FIG. 24 generally shows apelvic movement restraint 326 with a cross-section including a quarter circle.Pelvic restraint 326 may be made of firm material and provided with a tacky surface texture. For example, spray-on rubber may be applied on its outer surface. -
FIG. 25 generally illustrates apelvic movement restraint 328 comprising two hingedsurfaces FIG. 26 shows a pelvic movement restraint with a substantiallytubular body 340 that is closed at each end and filled with air to provide comfort and support for the user. The outer surface oftubular body 340 should have enough friction to be used in accordance with the present invention. Alternatively, spray-on rubber may be applied on the outer surface oftubular body 340 to provide the desired friction. - The lumbar muscle exercise system of the present invention is portable, easy to construct from inexpensive materials, and affordable. It allows the user to accurately target and strengthen his/her lumbar muscles using a relatively inexpensive and portable pelvic movement restraint. It also provides the user with an effective exercise solution for this critical area.
- The lumbar muscle exercise system of the present invention can provide the user with stronger, better working lumbar muscles relatively fast. That means more support, more flexibility and more protection for the spine, and a fitter, healthier lower back. In most cases, as low back strength increases, low back pain decreases, and the risk of injury to this vital area is reduced.
- The lumbar muscle exercise system of the present invention is designed to produce comparable results to top-of-the-line lumbar strengthening machines at a small fraction of the price. The pelvic restraint is lightweight, compact and easy to handle. It is made to provide comfort and safety while also giving users the required degree of resistance and grip to make it truly effective.
