Definitions
- the present invention generally relates to exercise equipment, and more particularly relates to devices for assisting with manual body stress exercises.
- plank exercise is a popular exercise that stresses the core muscles of the body such as the abdomen, lower back and upper legs.
- the plank exercise is utilized in a variety of exercise routines and is common in yoga studios and fitness classes. In fact, plank exercises are also often utilized by professional athletes.
- the plank exercise is relatively simple. As can be seen in FIGS. 1A and 1B of the drawings, the exercise is performed by maintaining the body in a straight position, like a “plank” of wood, while the body is supported by the forearms and feet. In the traditional plank exercise illustrated by FIG. 1A , both feet of the person rest on the floor or ground, while in the modified plank exercise illustrated by FIG. 1B , one foot engages the floor or ground and the ankle of the persons other leg rests atop the supporting leg. When performing a plank exercise, fitness enthusiasts attempt to maintain the plank position for as long as possible until failure. By maintaining the challenging plank position, the core muscles are stressed and subsequently strengthened.
- a traditional plank exercise is performed while lying on the floor.
- the degree and location of stress and strengthening that can be obtained from a traditional plank exercise is limited by the distance between the forearms and feet of the user, as well as the relative angle created between the user and the ground. Accordingly, since the distance between a user's forearms and feet is generally unchangeable, the degree and location of stress and strengthening accomplished by plank exercises is restricted. Furthermore, the conventional plank exercise places as much stress on the shoulders and arms as on the core muscles, and thus does not effectively target the core muscles.
- the present invention provides a novel apparatus that enables a user to perform a plank exercise while standing or sitting.
- a device for performing a standing plank exercise includes an elongated main body having a first lateral side, a second lateral side, a first axial end and a second axial end.
- a support pad that supports a user's back is positioned on the elongated main body between the first axial end and second axial end thereof.
- the device preferably further includes an ankle strap coupled to the elongated main body in proximity to the second axial end thereof which selectively joins the elongated main body to a portion of the body of the user.
- the elongated main body is preferably formed as at least two telescoping members that may be selectively extended and retracted within one another to vary the length of the elongated main body and the corresponding degree of stress placed on the user during the exercise.
- the device for performing a standing plank exercise may include a handle portion positioned perpendicularly to the elongated main body in proximity to the first axial end thereof, the handle portion being graspable by the user during the exercise.
- the exercise device of the present invention can apply a plank or other type of exercise to a person while the person is sitting.
- a primary tubular member in the form of a single elongated tube or a plurality of interconnected tubes extends from a perpendicularly disposed supporting base tubular member.
- Resilient or stretchable bands the ends of which are grasped by the user, may extend from diametrically opposite sides of the primary tubular member at different locations along the axial length thereof, and from the supporting base member.
- the band or bands may have different resistances in their elasticity, and such resistances may be denoted by different colors of the bands.
- a person using the sitting plank exerciser of the present invention may easily select a band of a particular resistance or elasticity, and may position the band at a desired location along the axial length of the primary tubular member to work different muscles in the user's body.

- the standing plank exercise device 2 formed in accordance with the present invention includes an elongated main body 4 in the form of a solid or tubular post and having a first axial end 6 and an oppositely disposed second axial end 8 .
- Padding or a cushion 10 may be wrapped around or secured to the elongated main body 4 to provide comfort for the user's body.
- the padding or cushion 10 is preferably selectively positionable on the elongated main body 4 between the first end 6 and second end 8 thereof.
- the padding or cushion 10 may be positioned approximately midway between the first end 6 and the second end 8 of the elongated main body 4 to provide comfort to the user's lower back and buttock area when the device 2 is positioned for use. Even more preferably, the cushion 10 is positioned at a pivot point or fulcrum on the elongated main body 4 during performance of standing plank exercisers, as will be realized from the further description of the device 2 and its operation.
- the padding or cushion 10 may include an adjustable clamp mechanism (not shown), for example, which engages the main body 4 to hold the cushion 10 in a desired position on the main body 4 .
- the device 2 may further include a handle portion 12 positioned in proximity to the first end 6 of the elongated main body 4 , the handle portion 12 generally being oriented perpendicularly to the axis of the elongated main body 4 .
- the handle portion 12 may be formed as a cross-member affixed perpendicularly to the elongated main body 4 in proximity to the first end 6 thereof.
- the handle portion 12 may be covered by padding or other material so that a user's hands may securely and comfortably grip the handle portion 12 during use.
- a user positions the elongated main body 4 behind him in a vertical orientation with the padding or cushion 10 against his lower back and buttock region.
- a strap such as a non-elastic or elastic band 14 , preferably forming part of the exerciser 2 , may be affixed to the exerciser 2 or just wrapped around the second end 8 of the elongated main body 4 and, in use, engages one ankle or both ankles 16 of the user. Accordingly, three contact points are created with the user's body (i.e., two contact points between the user's ankles and the elastic band 14 , and one contact point between the cushion 10 and the lower back region of the user).
- the strap or elastic band 14 that couples the user's ankles to the elongated main body 4 provides resistance to the forward directed force 18 applied to the first end 6 of the elongated main body 4 , thereby creating force across the abdominal and core musculature of the user during the exercise.
- the user can control how much force is applied to his abdominal and core musculature by varying the amount of forward directed force applied to the first end 6 of the elongated main body 4 against the bias of the elastic band 14 .
- beginners can apply less force and advanced users can apply more force to vary the degree of strain of the exercise.
- the greater the force applied to the elongated main body 4 by the user's hands the greater the force generated across the abdominal and core musculature of the user.
- the user can also increase the amount of force generated across the abdominal and core musculature by grasping the handle portion 12 and applying forward directed force thereto, which increases the moment arm of the force applied and generates a greater force across the abdominal and core musculature of the user.
- the user can also perform a number of alternative plank exercises with the device 2 formed in accordance with the present invention.
- a “superman plank” exercise can be performed by grasping the handle portion 12 and applying forward directed force thereto.
- a “side plank” exercise can be performed by positioning the plank exercise device 2 against the user's side, the cushion 10 resting against the user's hip, and drawing the upper portion 6 of the elongated main body 4 toward the user, this exercise works the side muscles of the core and abdomen.
- a “reverse plank” exercise can be performed by positioning the plank exerciser 2 in front of the user and pulling the upper end portion 6 of the main body 4 toward the user; this exercise works the lower back and upper leg muscles.
- the elongated main body 4 may also be formed so that its length may be selectively adjusted by a user. More specifically, as shown in FIGS. 2 and 3 of the drawings, the elongated main body 4 may be formed as a tubular member having at least a first telescoping member 20 and a second telescoping member 22 .
- the first telescoping member 20 preferably has an inner diameter that is greater than or equal to the outer diameter of the second telescoping member 22 so that the second telescoping member 22 may be received by and slide reciprocatingly within the first telescoping member 20 .
- a reducer 24 which effectively reduces the inner diameter of the first telescoping member 20 and may tighten against the first telescoping member 22 received thereby, preferably interconnects the first telescoping member 20 and the second telescoping member 22 and is fitted therebetween to align and center the second telescoping member 22 at least partially within the first telescoping member 20 , and preferably may be used to lock the two members 20 , 22 in place.
- the second telescoping member 22 may be selectively extended and retracted from the first telescoping member 20 to vary the overall length of the elongated main body 4 .
- the first and second telescoping members 20 , 22 may further include means for engaging one another to fix the elongated main body 4 to a desired length.
- the first telescoping member 20 may include one hole or a plurality of spaced apart holes 26 formed along at least a portion of the axial length thereof that may be aligned with one hole or a plurality of spaced apart holes 28 formed along at least a portion of the axial length of the second telescoping member 22 .
- a pin 30 or other fixation device may be inserted through the holes 26 formed in the first telescoping member 20 and through the corresponding aligned holes 28 formed in the second telescoping member 22 to engage and lock the first and second telescoping members 20 , 22 together in a desired overall length.
- the first telescoping member 20 may be formed with a plurality of detents or other protrusions (not shown) that may engage the holes or recesses or dimples (not shown) in the second telescoping member 22 once aligned.
- first and second telescoping members 20 , 22 configured so that the first telescoping member 20 is received by the second telescoping member 22 and may be selectively extendable therefrom and retractable therein.
- a user may adjust the device 2 to a variety of different lengths to provide different degrees of stress as well as provide the device 2 with the ability to be stored in a compact state.

Description
- This application is a continuation-in-part of U.S. application Ser. No. 15/982,535, filed on May 17, 2018, and entitled “Device For Performing A Standing Plank Exercise”, the disclosure of which is incorporated herein by reference and on which priority is hereby claimed.
- The present invention generally relates to exercise equipment, and more particularly relates to devices for assisting with manual body stress exercises.
- The plank exercise is a popular exercise that stresses the core muscles of the body such as the abdomen, lower back and upper legs. The plank exercise is utilized in a variety of exercise routines and is common in yoga studios and fitness classes. In fact, plank exercises are also often utilized by professional athletes.
- The plank exercise is relatively simple. As can be seen in
FIGS. 1A and 1B of the drawings, the exercise is performed by maintaining the body in a straight position, like a “plank” of wood, while the body is supported by the forearms and feet. In the traditional plank exercise illustrated byFIG. 1A , both feet of the person rest on the floor or ground, while in the modified plank exercise illustrated byFIG. 1B , one foot engages the floor or ground and the ankle of the persons other leg rests atop the supporting leg. When performing a plank exercise, fitness enthusiasts attempt to maintain the plank position for as long as possible until failure. By maintaining the challenging plank position, the core muscles are stressed and subsequently strengthened. - A traditional plank exercise is performed while lying on the floor. The degree and location of stress and strengthening that can be obtained from a traditional plank exercise is limited by the distance between the forearms and feet of the user, as well as the relative angle created between the user and the ground. Accordingly, since the distance between a user's forearms and feet is generally unchangeable, the degree and location of stress and strengthening accomplished by plank exercises is restricted. Furthermore, the conventional plank exercise places as much stress on the shoulders and arms as on the core muscles, and thus does not effectively target the core muscles.
- The present invention provides a novel apparatus that enables a user to perform a plank exercise while standing or sitting.
- It is an object of the present invention to provide a device for performing a standing plank exercise.
- It is another object of the present invention to provide a device for performing a standing plank exercise that focuses the exercise on the user's core muscles.
- It is yet another object of the present invention to provide a device for performing a standing plank exercise which is selectively adjustable in length to vary the degree of stress placed on the user during the exercise.
- It is a further object of the present invention to provide a device for performing a sitting plank exercise.
- It is still a further object of the present invention to provide a device for performing a sitting plank exercise that focuses the exercise on the user's core muscles.
- It is yet a further object of the present invention to provide a device for performing a sitting plank exercise which includes structure for the user to vary the degree of stress placed on the user during the exercise.
- In one form of the present invention, a device for performing a standing plank exercise includes an elongated main body having a first lateral side, a second lateral side, a first axial end and a second axial end. A support pad that supports a user's back is positioned on the elongated main body between the first axial end and second axial end thereof.
- The device preferably further includes an ankle strap coupled to the elongated main body in proximity to the second axial end thereof which selectively joins the elongated main body to a portion of the body of the user.
- The elongated main body is preferably formed as at least two telescoping members that may be selectively extended and retracted within one another to vary the length of the elongated main body and the corresponding degree of stress placed on the user during the exercise.
- In another form of the present invention, the device for performing a standing plank exercise may include a handle portion positioned perpendicularly to the elongated main body in proximity to the first axial end thereof, the handle portion being graspable by the user during the exercise.
- In yet another embodiment, the exercise device of the present invention can apply a plank or other type of exercise to a person while the person is sitting. In one form of this sitting plank exerciser, a primary tubular member in the form of a single elongated tube or a plurality of interconnected tubes extends from a perpendicularly disposed supporting base tubular member. Resilient or stretchable bands, the ends of which are grasped by the user, may extend from diametrically opposite sides of the primary tubular member at different locations along the axial length thereof, and from the supporting base member. The band or bands may have different resistances in their elasticity, and such resistances may be denoted by different colors of the bands. In this way, a person using the sitting plank exerciser of the present invention may easily select a band of a particular resistance or elasticity, and may position the band at a desired location along the axial length of the primary tubular member to work different muscles in the user's body.
- These and other objects, features and advantages of the present invention will be apparent from the following detailed description of illustrative embodiments thereof, which is to be read in connection with the accompanying drawings.

FIGS. 2 and 3 of the drawings, the standingplank exercise device 2 formed in accordance with the present invention includes an elongatedmain body 4 in the form of a solid or tubular post and having a firstaxial end 6 and an oppositely disposed secondaxial end 8. Padding or acushion 10 may be wrapped around or secured to the elongatedmain body 4 to provide comfort for the user's body. The padding or cushion 10 is preferably selectively positionable on the elongatedmain body 4 between thefirst end 6 andsecond end 8 thereof. For example, the padding or cushion 10 may be positioned approximately midway between thefirst end 6 and thesecond end 8 of the elongatedmain body 4 to provide comfort to the user's lower back and buttock area when thedevice 2 is positioned for use. Even more preferably, thecushion 10 is positioned at a pivot point or fulcrum on the elongatedmain body 4 during performance of standing plank exercisers, as will be realized from the further description of thedevice 2 and its operation. The padding or cushion 10 may include an adjustable clamp mechanism (not shown), for example, which engages themain body 4 to hold thecushion 10 in a desired position on themain body 4. - As shown in
FIGS. 2 and 3 of the drawings, thedevice 2 may further include ahandle portion 12 positioned in proximity to thefirst end 6 of the elongatedmain body 4, thehandle portion 12 generally being oriented perpendicularly to the axis of the elongatedmain body 4. - The
handle portion 12 may be formed as a cross-member affixed perpendicularly to the elongatedmain body 4 in proximity to thefirst end 6 thereof. Thehandle portion 12 may be covered by padding or other material so that a user's hands may securely and comfortably grip thehandle portion 12 during use. - As can be seen in
FIGS. 4-7 of the drawings, to utilize thedevice 2, a user positions the elongatedmain body 4 behind him in a vertical orientation with the padding or cushion 10 against his lower back and buttock region. A strap, such as a non-elastic orelastic band 14, preferably forming part of theexerciser 2, may be affixed to theexerciser 2 or just wrapped around thesecond end 8 of the elongatedmain body 4 and, in use, engages one ankle or bothankles 16 of the user. Accordingly, three contact points are created with the user's body (i.e., two contact points between the user's ankles and theelastic band 14, and one contact point between thecushion 10 and the lower back region of the user). The user then outstretches his arms towards thefirst end 6 of the elongatedmain body 4 and grasps either the elongatedmain body 4 with his hands, as shown inFIG. 4 , or thehandle portion 12, as shown inFIG. 5 . To perform the standing plank exercise, the user holds the elongatedmain body 4 from behind and exerts a forward directed force (the forward directed force is shown by the arrow andcorresponding reference number 18 inFIG. 5 of the drawings). The strap orelastic band 14 that couples the user's ankles to the elongatedmain body 4 provides resistance to the forward directedforce 18 applied to thefirst end 6 of the elongatedmain body 4, thereby creating force across the abdominal and core musculature of the user during the exercise. - The user can control how much force is applied to his abdominal and core musculature by varying the amount of forward directed force applied to the
first end 6 of the elongatedmain body 4 against the bias of theelastic band 14. For example, beginners can apply less force and advanced users can apply more force to vary the degree of strain of the exercise. The greater the force applied to the elongatedmain body 4 by the user's hands, the greater the force generated across the abdominal and core musculature of the user. Furthermore, the user can also increase the amount of force generated across the abdominal and core musculature by grasping thehandle portion 12 and applying forward directed force thereto, which increases the moment arm of the force applied and generates a greater force across the abdominal and core musculature of the user. - The user can also perform a number of alternative plank exercises with the
device 2 formed in accordance with the present invention. For example, as shown inFIG. 5 of the drawings, a “superman plank” exercise can be performed by grasping thehandle portion 12 and applying forward directed force thereto. Additionally, as shown inFIG. 6 of the drawings, a “side plank” exercise can be performed by positioning theplank exercise device 2 against the user's side, thecushion 10 resting against the user's hip, and drawing theupper portion 6 of the elongatedmain body 4 toward the user, this exercise works the side muscles of the core and abdomen. Furthermore, as shown inFIG. 7 of the drawings, a “reverse plank” exercise can be performed by positioning theplank exerciser 2 in front of the user and pulling theupper end portion 6 of themain body 4 toward the user; this exercise works the lower back and upper leg muscles. - The elongated
main body 4 may also be formed so that its length may be selectively adjusted by a user. More specifically, as shown inFIGS. 2 and 3 of the drawings, the elongatedmain body 4 may be formed as a tubular member having at least afirst telescoping member 20 and asecond telescoping member 22. Thefirst telescoping member 20 preferably has an inner diameter that is greater than or equal to the outer diameter of thesecond telescoping member 22 so that thesecond telescoping member 22 may be received by and slide reciprocatingly within thefirst telescoping member 20. Areducer 24, which effectively reduces the inner diameter of thefirst telescoping member 20 and may tighten against thefirst telescoping member 22 received thereby, preferably interconnects thefirst telescoping member 20 and thesecond telescoping member 22 and is fitted therebetween to align and center thesecond telescoping member 22 at least partially within thefirst telescoping member 20, and preferably may be used to lock the twomembers second telescoping member 22 may be selectively extended and retracted from thefirst telescoping member 20 to vary the overall length of the elongatedmain body 4. - The first and
second telescoping members main body 4 to a desired length. For example, as shown inFIG. 2 of the drawings, thefirst telescoping member 20 may include one hole or a plurality of spaced apart holes 26 formed along at least a portion of the axial length thereof that may be aligned with one hole or a plurality of spaced apart holes 28 formed along at least a portion of the axial length of thesecond telescoping member 22. Once the elongatedmain body 4 has been adjusted to a desired length (i.e., by selectively extending or retracting thesecond telescoping member 22 from the first telescoping member 20), apin 30 or other fixation device may be inserted through theholes 26 formed in thefirst telescoping member 20 and through the corresponding alignedholes 28 formed in thesecond telescoping member 22 to engage and lock the first andsecond telescoping members first telescoping member 20 may be formed with a plurality of detents or other protrusions (not shown) that may engage the holes or recesses or dimples (not shown) in thesecond telescoping member 22 once aligned. Of course, it is envisioned to be within the scope of the present invention to use other means to lock thetelescoping members second telescoping members first telescoping member 20 is received by thesecond telescoping member 22 and may be selectively extendable therefrom and retractable therein. During use, a user may adjust thedevice 2 to a variety of different lengths to provide different degrees of stress as well as provide thedevice 2 with the ability to be stored in a compact state. -
FIGS. 8A-13 of the drawings illustrate another version of theplank exerciser 40 formed in accordance with the present invention, thisplank exerciser 40 being structured to allow a person to perform exercises while safely sitting in achair 42. Reference should initially be had toFIGS. 8A-8C of the drawings, which show the structure of a preferred form of the sittingplank exerciser 40 of the present invention. - With reference to
FIGS. 8A-8C , it will be seen that the sittingplank exerciser 40 of the present invention includes aprimary member 44 and a supportingbase member 46 affixed to theprimary member 44. Theprimary member 44 is preferably formed as an elongated, one-piece, hollow tube, as shown inFIG. 8A of the drawings, or as multiple, hollow tubular components joined together, as shown inFIGS. 8B and 8C . - The
primary tubular member 44, either formed in one section or multiple sections, has a first or topaxial end 48 and a second or bottomaxial end 50 situated axially opposite to the firstaxial end 48. Preferably, the first and second axial ends 48, 50 are open to define openings for receiving other parts of the sittingplank exerciser 40. - The supporting
base member 46 is also preferably formed as a generally tubular, hollow, elongated or T-shaped member that is affixed to the bottomaxial end 50 of theprimary tubular member 44. More specifically, the supportingbase member 46 includes a firsttubular component 52 and a secondtubular component 54 situated midway on the axial length of the firsttubular component 52 and extending perpendicularly therefrom. This secondtubular component 54 of the supportingbase member 46 is preferably received by the opening formed in the second or bottomaxial end 50 of theprimary tubular member 44 such that the longitudinal axis of the firsttubular component 52 of the supportingbase member 46 extends in a perpendicular direction to the longitudinal axis of theprimary tubular member 44. Alternatively, the secondtubular component 54 of the supportingbase member 46 may be formed with an axial open end defining an opening therein into which is received the second or bottomaxial end 50 of theprimary tubular member 44 to join theprimary tubular member 44 and the supportingbase member 46 together. The supportingbase member 46 may be permanently joined to theprimary tubular member 44 by using an adhesive or bonding agent, or may be integrally formed with theprimary tubular member 44, or may be removably affixed to theprimary tubular member 44 so that the sittingplank exerciser 40 of the present invention may be conveniently disassembled for storage when not in use. - A grasping
piece 56, also preferably formed as a T-shaped, hollow tubular member, is affixed to the first or topaxial end 48 of the elongated,primary tubular member 44. Like the supportingbase member 46, the graspingpiece 56 preferably includes a firsttubular component 58 and a secondtubular component 60 situated midway on the axial length of the firsttubular component 58 and extending perpendicularly therefrom. This secondtubular component 60 of the graspingpiece 56 is preferably received by the opening formed in the first or topaxial end 48 of theprimary tubular member 44 such that the longitudinal axis of the firsttubular component 58 of the graspingpiece 56 extends in a perpendicular direction to the longitudinal axis of theprimary tubular member 44. Alternatively, the secondtubular component 60 of the graspingpiece 56 may have an axial end in which is formed an opening that receives the first or topaxial end 48 of theprimary tubular member 44 to join the graspingpiece 56 and theprimary tubular member 44 together. The graspingpiece 56 may be permanently joined to theprimary tubular member 44 at the first or topaxial end 48 thereof by using an adhesive or bonding agent, or may be integrally formed with theprimary tubular member 44, or may be removably affixed to theprimary tubular member 44 so that the sittingplank exerciser 40 of the present invention may be disassembled for storage. - As may be seen from
FIG. 8A of the drawings, theprimary tubular member 44 may include a plurality ofopenings 62 a, 62 b formed through the thickness of its sidewall, adjacent openings being periodically spaced from each other along at least a portion of the longitudinal length thereof. More specifically, there are a first pair of alignedopenings 62 a formed through the sidewall thickness of theprimary tubular member 44 and situated diametrically opposite one another, and at least a second pair of aligned openings 62 b formed through the sidewall thickness and situated diametrically opposite one another. Theseopenings 62 a, 62 b are provided to allowelastic bands 64, the free ends of which may be grasped by the user and used when performing an exercise, to pass diametrically through theprimary tubular member 44, that is, through the first pair ofopenings 62 a and/or the second pair of openings 62 b. Additionally, the firsttubular component 52 of the supportingbase member 46 may have opposite open axial ends defining openings in communication with the bore of the firsttubular component 52 through which yet anotherelastic band 64 extends and outwardly of the opposite axial ends thereof which, as with the otherelastic bands 64, may be grasped at its free ends by a user performing exercises with the sittingplank exerciser 40 of the present invention. Furthermore, the firsttubular component 58 of the graspingpiece 56 may include opposite open axial ends defining openings which communicate with the bore of the firsttubular component 58 of the graspingpiece 56 through which a furtherelastic band 64 may extend and outwardly of the opposite axial ends thereof, thisband 64 also being graspable at its free ends by a user of the sittingplank exerciser 40 of the present invention. - Any one of the
elastic bands 64 may be selectively grasped by a user of the sittingplank exerciser 40 of the present invention to perform exercises when the person is in a sitting position. Eachband 64 may have a different elasticity or resistance, andsuch bands 64 may have different colors to signify the different resistances which they provide. The user of the sittingplank exerciser 40 of the present invention may select anelastic band 64 providing a particular resistance, and may easily interchange thebands 64 through theopenings 62 a, 62 b formed in theprimary tubular member 44, the graspingpiece 56 and the supportingbase member 46 before or during an exercise regime. - An alternative embodiment of the sitting
plank exerciser 40 of the present invention is shown inFIGS. 8B and 8C of the drawings. Here, and as stated previously, theprimary tubular member 44 may be formed of several cooperating components or sections. More specifically, and in one preferred form of theexerciser 40 of the present invention, theprimary tubular member 44 includes a lowerfirst tubular section 66 and an upper secondtubular section 68 situated co-axially with the lowerfirst tubular section 66, the twotubular sections tubular section 70 interposed between the first andsecond sections - Even more specifically, the
first section 66 of theprimary tubular member 44 includes a first openaxial end 72 which receives or mates with the secondtubular component 54 of the supportingbase member 46, and an opposite second openaxial end 74. Thesecond section 68 of theprimary tubular member 44 includes a first openaxial end 76 which receives or mates with the secondtubular component 60 of the graspingpiece 56, and an opposite second openaxial end 78. - The four-way, mid-positioned,
tubular section 70 includes a firsttubular component 80 and a pair of opposite secondtubular components 82 which extend perpendicularly to the longitudinal axis of the firsttubular component 80. Each of the first and secondtubular components mid-positioned section 70 preferably includes opposite open axial ends that define openings. The secondaxial end 74 of thefirst section 66 of theprimary tubular member 44 receives or mates with the axial end of one of thesecond components 82 of the pair of secondtubular components 82 of the four-way,mid-positioned section 70, and the secondaxial end 78 of thesecond section 68 of theprimary tubular member 44 receives or mates with the axial end of the othersecond component 82 of the pair of secondtubular components 82 of the four-way,mid-positioned section 70. - The first
tubular component 80 of the four-way section 70 includes a bore extending axially therethrough to receive anelastic band 64 that extends outwardly from each open axial end thereof and which is graspable at its free ends by a user of the sittingplank exerciser 40 of the present invention. Similarly, just like the embodiment of the sittingplank exerciser 40 shown inFIG. 8A , theexerciser 40 shown inFIGS. 8B and 8C preferably includes anelastic band 64 that extends through the bore of the firsttubular component 58 of the graspingpiece 56 and out of the open axial ends of thefirst component 58 thereof, and anelastic band 64 that extends through the bore of the firsttubular component 52 of the supportingbase member 46 and extends outwardly from the open axial ends of thefirst component 52 thereof. Again, like the first embodiment of the sittingplank exerciser 40 shown inFIG. 8A of the drawings, the components of theexerciser 40 shown inFIGS. 8B and 8C , including the supportingbase member 46, the firsttubular section 66, the four-way,mid-positioned section 70, the secondtubular section 68 and the graspingpiece 56, may be permanently joined together by using an adhesive or bonding agent, or may be integrally formed together, or may be removably affixed to their adjoining components so that the sittingplank exerciser 40 of the present invention shown inFIGS. 8B and 8C may be conveniently disassembled for storage when not in use. Furthermore, theelastic bands 64 used in the sittingplank exerciser 40 shown inFIGS. 8B and 8C preferably offer different resistances and are color-coded to differentiate one from the other, and may be easily interchanged by the user by passing thebands 64 through the open axial ends of the firsttubular components piece 56 and the supportingbase member 46, and through the four-way,mid-positioned section 70 of theprimary tubular member 44. - Reference should now be had to
FIGS. 9-13 of the drawings, which illustrate different ways in which the sittingplank exerciser 40, either the embodiment shown inFIG. 8A or the embodiment shown inFIGS. 8B and 8C , may be used by a person sitting in achair 42. - More specifically,
FIG. 9 illustrates use of the sittingplank exerciser 40 in which the exerciser simulates the standard plank exercise performed by a person, such as shown inFIGS. 1A and 1B .
