It is to be understood that the phraseology and terminology used in the following description are used for the purpose of description and element, and should not be regarded as limiting. Additionally, in the following description, it is understood that terms such as top, bottom, side, front, back, inner, outer, and the like, are words of convenience and are not to be construed as limiting terms. FIG. 1 is added to show a general side view of hip joint range of motion and FIG. 2 is added to show a radius of the previous bicycle swing arm.

[0035] The invention is described herein. The embodiments of the present invention are designed to provide an upper leg and hip exercise machine that avoids force on user's knee and ankle joint by placing movement arm assembly on the user's upper leg during exercise performance. In addition, user's body is in sitting or lying position throughout the exercise motion to decrease stress on the resting joint of the leg.

[0036] Further the embodiments of the present invention is designed to provide more effective upper leg and hip exercise device by placing the movement arm axis aligned with the hip joint or by providing diverse movement axes by placing two different axes in a single movement arm. In addition, it provide a combination of said device with bicycle which moves forward when the arm rotates clockwise and idles when it moves counterclockwise. In this manner the bicycle moves forward with axis pivotally attached near the hip joint while the movement arm assembly is placed on the back of the use's knees.

[0037] An embodiment of the present invention include a user support 20, and at least one movement arm 32 pivotally attached to the frame near with the user's hip joint, and at least one member 56 pivotally attached to be placed on the back or front of user's upper leg, and an exercise arm axle 44. A user torso support 26, and at least one foot plate 61, and at least one knee support 63, and handles positioned forward of the torso support 20 is preferable.

[0038] FIGS. 4 and 7, show practical example of the invention include. The main frame is a fixed frame structure and includes a horizontal side strut 18, 19; a horizontal cross strut 14; a support upright 15; a vertical exercise arm support member 12, and a horizontal connecting strut 15. The main frame 10 also includes support feet 61 at the support upright 15. The main frame 10 includes a torso support 26 on the support upright 15 which a torso support pad is mounted to support the user's upper torso during performance of the exercise. The torso support is designed to be placed in front of the user's chest in a practical example of the invention shown in FIG. 4, 6, 7. However the torso support is designed to be placed on back of the user in a practical example of the invention shown in FIG. 11, 12, 13. The exercise device preferably comprises torso incline angle adjustment assembly 27 and movement arm length adjustment 52. The main frame 10 supports the seat of the user and provides a fixed structure to which moving assemblies are connected (FIG. 3, 6, 8). Otherwise the main frame supports the moving assemblies and the weight stack while the user's weight is supported by the seat (FIG. 4, 7). In the case of bicycle, the frame is a bicycle frame.

[0039] A practical example of the invention include a resistance exercise device as depicted in FIGS. 3,4,6,7,8,9,10, which in the case of the embodiment depicted in FIGS. 3,6,7,8 is a selectorized weight stack assembly 71. However, that the source of resistance may include, without limitation, a weight stack, weight plates mounted on pegs (FIG. 4,10), or other types of resistance such as hydraulic, pneumatic, electromagnetic, friction, springs, elastically bending rods, elastic bands (FIG. 9), or the like. The selectorized weight stack assembly 71 is connected to the main frame 10 at the ends of connecting strut and weight stack support strut. One skilled in the art will recognize the methods of providing resistance, and these alternative methods are within the scope of the present invention.

[0040] The present invention, as depicted in FIGS. 3-25, further includes an exercise arm assembly 56. The exercise arm assembly includes at least one assembly pivotally attached on the rear end of the rotating exercise arm 32 to be placed on the user's back or front of the thigh wherein said has a pad support and pivot bracket. In a practical example of the present invention, the rotating exercise arm 32 has a pivot sleeve 36 and a pull pin that allows a user to adjust the position and orientation of the exercise arm assembly in the exercise starting position (FIG. 4), and includes selectorized movement arm angle adjustment assembly 34 which is connected between the movement arm 100 and frame 10 (FIG. 11,15,16). The opposite, front end of the rotating exercise arm has a counterweight 49 that balances the exercise arm assembly, so that it's position and orientation may be more easily adjusted. A safety pin (50) is located to prevent arm from rotating over the user's range of motion (FIG. 4).

[0041] In a practical example of the present invention, the exercise arm 32 preferably comprises a knee pad mounted on the end of the movement arm and configured for engagement by a respective knee of the user's leg (not shown).
