An apparatus for use in exercising selected lower body muscles and joints of a user\s body. The apparatus is adjustable to accommodate users of various sizes and dimensions. The machine comprises a frame including a base and support members fixed to said base, a resistance mechanism providing an adjustable resistance force to a fixed location on the support members, and a movable portion for transferring the adjustable resistance force to user elements. The movable portion includes adjustable elements for positioning the movable portions with respect to the base and the support members, and for adapting the apparatus for exercises requiring forces in either clockwise or counterclockwise rotational movements to permit exercise of selected muscles and joints by movement of the resistance mechanism. A bench surface is supported on the frame in a manner to be positioned in an “in use”or a “storage”position.
