- the exercise device includes a seat configured to support the user in the sitting or lying position and the arm rotatably attached within a radius of 20 cm from the user's pelvis in a sagittal plane, wherein the end of the arm is configured to contact the user's thighs during use.
- the exercise device includes various resistive force generators each configured to generate a resistive force against a force exerted by the user to rotate an arm portion. Also, the exercise device according to the present disclosure includes a shaft changing portion configured to allow the user to change a direction of an arm pivot axis. The exercise device according to another embodiment of the present disclosure includes two different pivot axis provided on one arm portion.
- the exercise device includes two different arm shafts provided on one arm portion.

- Thigh and hip muscles account for more than a third of all muscles in our body. Building thigh and hip muscles may reduce the risk of diabetes, etc., may prevent obesity, and may promote health after middle age, and may also help to improve the physical fitness and sport ability of athletes.
- the present disclosure is configured to reduce a force transmitted to the knees and ankles by enabling a user to locate a foot plate or a foot pad of an exercise machine connected to a weight on his/her thigh and pull his/her legs toward the chest and push them backward in a sitting, lying, or prone position.
- the exercise machine includes a shaft changing portion configured to allow the user to change a direction of an arm shaft.
- the arm shaft may be rotatable in a direction in which the user's legs are extended.
- the arm shaft may be movable in a direction in which the user's legs are adducted and laterally rotated.
- the exercise device includes two different arm shafts on one arm so that rotations about different axes are simultaneously performed and lateral rotation and adduction are simultaneously performed.

The present application has the same inventor as the aforementioned application.
- The present disclosure relates to an exercise method and an exercise device for performing exercises suitable to strengthen thigh and hip muscles while protecting the knees and ankle joints such as a leg press machine, a total hip, a stationary bicycle, or a moving bicycle, and more particularly, to an exercise method and an exercise device for strengthening thigh and hip muscles while protecting knee and angle joints by enabling a user to locate a lower end of an arm on his/her thighs in a sitting or lying position and move his/her legs.
- To this end, the exercise device according to the present disclosure includes a seat configured to support the user in the sitting or lying position and the arm rotatably attached within a radius of 20 cm from the user's pelvis in a sagittal plane, wherein the end of the arm is configured to contact the user's thighs during use.
- The exercise device according to an embodiment of the present disclosure includes various resistive force generators each configured to generate a resistive force against a force exerted by the user to rotate an arm portion. Also, the exercise device according to the present disclosure includes a shaft changing portion configured to allow the user to change a direction of an arm pivot axis. The exercise device according to another embodiment of the present disclosure includes two different pivot axis provided on one arm portion.
- The exercise device according to another embodiment of the present disclosure includes two different arm shafts provided on one arm portion. In addition, the exercise device is applied to a bicycle so that the arm shaft of the arm portion is located on hip joints and an end of the arm is placed on the back of the thighs, and the exercise device propels the bicycle by rotating when the arm portion rotates clockwise and idling when the arm portion rotates counterclockwise to drive a rear wheel.
- Thigh and hip muscles account for more than a third of all muscles in our body. Building thigh and hip muscles may reduce the risk of diabetes, etc., may prevent obesity, and may promote health after middle age, and may also help to improve the physical fitness and sport ability of athletes.
- However, exercises for strengthening thigh and hip muscles apply a load to ankle and knee joints, and thus knee osteoarthritis and chondromalacia are common among people who do strength training. Also, it is difficult for people with weak knees and ankle joints such as elders or obese people to perform exercises for strengthening thigh and hip muscles. Accordingly, there is a demand for an exercise device for training thigh and hip muscles without adding stress to the knees and joints. In general, a user performs an exercise for strengthening thigh and hip muscles by pulling his/her legs toward the chest and pushing them outward with the pelvis as an axis, as shown in
FIG. 1 . However, existing exercise methods and exercise devices may damage the knees and ankle joints because a load is directly transmitted to the ankles and knees, and thus it is not suitable for people with weak knees and ankle joints to use the existing exercise methods and exercise devices. Accordingly, the present disclosure is configured to reduce a force transmitted to the knees and ankles by enabling a user to locate a foot plate or a foot pad of an exercise machine connected to a weight on his/her thigh and pull his/her legs toward the chest and push them backward in a sitting, lying, or prone position. - When the exercise device according to an embodiment of the present disclosure is used, the user's thigh and hip muscles are all involved in lateral rotation and adduction as well as extension of the hip joints. Accordingly, the exercise machine according to an embodiment of the present disclosure includes a shaft changing portion configured to allow the user to change a direction of an arm shaft. The arm shaft may be rotatable in a direction in which the user's legs are extended. Also, the arm shaft may be movable in a direction in which the user's legs are adducted and laterally rotated. The exercise device according to another embodiment of the present disclosure includes two different arm shafts on one arm so that rotations about different axes are simultaneously performed and lateral rotation and adduction are simultaneously performed.
- In addition, the exercise device according to another embodiment of the present invention includes a bicycle frame. In an existing bicycle, since a hip joint motion range is limited to a rotation diameter of a crank arm to which a pedal is attached, as shown in
FIG. 2 , the user's lower body is repeatedly moved only in a small space. Accordingly, when the exercise device is implemented as a bicycle an arm pivot axis of an arm is fixed to the user's hip joints, the exercise machine includes a propelling device for propelling the bicycle by rotating when the arm rotates clockwise and idling when the arm rotates counterclockwise to drive a rear wheel. - In general, a user performs an exercise for strengthening thigh and hip muscles by pulling the legs toward the chest and pushing them outward with the pelvis as an axis, as shown in
FIG. 1 . Also, in a general bicycle, since a high hip motion range is limited to a rotation radius of a crank connected to a bicycle pedal, as shown inFIG. 2 , the user's exercise is repeatedly performed only in a relatively small space when compared to the high hip motion range, and thus exercise efficiency in utilization of thigh and hip muscles is limited. - According to the present disclosure, an exercise method and an exercise device for strengthening thigh and hip muscles reduce a load applied to the legs by enabling a user to have a sitting, lying, or prone position during an exercise activity. Also, the exercise method and the exercise device minimize a load transmitted to the knees and ankle joints by enabling the user to move his/her legs after locating lower ends of arm portions on his/her thigh instead of the ankles or soles. The exercise method and the exercise device improve the exercise effect of strengthening thigh and hip muscles by increasing a hip joint motion range and a rotation axis.
