ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an exercise apparatus and more particularly the present invention which is directed to an exercise apparatus for the conditioning of the three groups of muscles, the hamstring muscle, the quadriceps muscle and the maximus gluteus muscle.
2. Description of the Prior Art
Many devices exist for exercising various parts of the body for commercial and home use. Some of these devices are:
U.S. Pat. No. 5,575,741 to Robert Fan.
This exercise apparatus simulates horse riding type and rowing type exercise.
U.S. Pat. No. 4,526,013 to W. R. Dofel.
This exercise device provides a mechanical resistance assembly which employs a resistant strap which is stretched by use of a pulley system pulled by the user.
U.S. Pat. No. 5,094,450 to Steams.
This exercise machine provides for abdominal exercising. This machine also allows a chest pod to rotate, which is resisted by either a viscous fluid resistance or stacked weights.
U.S. Pat. No. 5,112,287 to Brewer.
This exercise apparatus employs a resistance that is experienced by a person exerting a force to pull or push the body engaging members. The resistance can be varied.
SUMMARY OF THE INVENTION
It is the object of the present invention to provide an exercise apparatus useful in connection with the performance of exercising at least three groups of muscles.
It is another object of the present invention to exercise the maximus gluteus muscle in addition to two leg muscles.
It is yet another object of the present invention to provide an exercise apparatus that can be efficient and economically manufactured.
Briefly, in accordance with the present invention, there is provided an exercise apparatus that sits on a floor surface and has an rectangular backrest. Two semi-circular members attached to the backrest also sit on a floor surface. Pivotally attached to the backrest is a brace that has a roller resting on the floor surface on the other end. The brace has a sliding member that is fit over the brace and the sliding member is adjusted by push pins. The sliding member adjusts the tension in the tensioning members. Two handlebars are attached to the lower end of the backrest of the exercise equipment When a person exercising pushes back on the backrest, the backrest rotates and lifts the person exercising off the floor surface. The person exercising pushes back as far as desired and then relaxes and the person exercising will return to sit on the floor surface. This movement is repeated until a complete workout is obtained in the three previously mentioned muscle groups. It is noted that a person exercising must hold their feet flat on the floor. A person exercising must also have non-slip shoes such as gym shoes to provide the ability to push back on the backrest of the exercise equipment.
These and other objects, features and advantages of the present invention will become more readily apparent upon detail consideration of the following Description of the Preferred Embodiment with reference to the accompanying drawings.
