Abstract
Abstract An exercise device which includes a pair of side frames extending substantially vertical in parallel position and held in relatively fixed position by cross members. An extension projects from one end of each side frame and a padded horizontally disposed bar is adjustably fixed between said extensions and is adapted to engage the front of the leg of an exerciser at approximately the height of his ankle. A padded leg support member adapted to engage the back of an exerciser''s leg at about his calf extends between the side frames above the bar and is vertically movable on the side frames to accommodate movements of the exerciser.

A device for exercising and strengthening the leg muscles by specific structural support means which allow the exerciser to move successively from standing position to modified squat position where his legs from ankle to knee are substantially vettical and from knee to hip are inclined downward, said structure comprising, a pair of horixontal elements for engaging the floor or the like, a pair of vertical elements extending upward from said horizontal elements, one vertical element being rigidly attached to each horizontal elements, a pair of sloping elements, each said element extending from one end rigidly fixed to one vertical element near the top thereof to another end rigidly fixed to near one end of its attached horizontal elements, said elements forming two separate and generally triangularshaped frame elements, said frame elements being locked together to stand upright in vertical, substantially parallel planes by cross pieces extending between the two frames and being attached to each frame, means projecting from each vertical elements for mounting an ankle bar means; ankle bar means for engaging the front of the leg of the exerciser at about the ankle mounted to said projecting means, a cross bar means mounted horizontally to slide up and down on the two vertical elements during the squatting exercise for preventing binding and pinching of the exerciser''s skin during its stretching and contraction, said cross bar means comprising a bar extending between the vertical elements with its opposite ends including means loosely circumscribing said vertical elements, the horizontal spacing of the ankle bar and the cross bar means being about the diameter of the exerciser''s leg whereby the exerciser''s leg is held substantially vertical from ankle to knee during the exercise, the vertical spacing of the ankle bar and the cross bar means being about the distance from the exerciser''s ankle to his calf, said last named distance being adjustable due to the loose sliding fit of the cross bar means on the vertical elements.
