ABSTRACT:
An aerobic exercise device featuring a vertically movable seat counter-balanced mainly by a spring. As a user, supported by the seat, executes a squatting exercise the seat will urge the user toward an initial position. The seat moves vertically along an upright column having a pulley at its top. A cable connects the seat to a spring at the back side of the column via the pulley. Handles are suspended from arms at the top of the column to help a user support his or her weight.
