Universal exercise apparatus for performing hamstring flex and other exercises

Abstract

The exercise apparatus includes a table having a longitudinal dimension; a set of rails disposed longitudinally on opposite sides of the table; a set of posts on opposite sides of the table adjustably supported on the rails for longitudinal movement along the rails and for vertical movement extending above the rails; mechanisms for securing the posts in a fixed position on the rails. A rotary hydraulic actuator is supported on one of the posts for providing a predetermined constant resistance to rotary motion about its axis in a given direction. A bearing is supported on the post on the opposite side of the table from and axially aligned with the rotary hydraulic actuator. The apparatus has a pair of parallel arms that are adjustable in length respectfully coupled to the bearing and the rotary hydraulic actuator; and a cross bar coupled between the arms at a distance from the common axis of the bearing and the rotary hydraulic actuator for enabling a person to exercise his muscles by contacting the cross bar and forcing the cross bar to move against the predetermined constant resistance provided by the rotary hydraulic actuator. Adjustable valves are attached to the rotary hydraulic actuator for adjusting the predetermined constant resistance to movement in each given direction of rotary motion.
