Abstract

Exercise apparatus for strengthening the legs and hips of a user. A weight carrying pivot arm rides up and down a pivotable mast when the user squats and rises, causing the resistance of the apparatus to increase as the user approaches a standing position. An optional toe plate may be added to allow exercise of ankle and foot structures.
