Abstract
Abstract The invention is an aerial gymnastic exerciser having a pair of handles depending from cords threaded through compound pulley systems located between upper and lower supports with a body harness depending from the lower support. Increase or decrease in resistance to operation of the exerciser by an operator suspended in the harness and pulling on the handles is achieved by a plurality of removable weights depending from one end of cords passing upward and over part of the pulley systems and back downward with the other ends secured to the handles. Other modifications for resistance can be by either removable weights secured to the lower support, or by removable clothespin type springs with respective ends of each removably secured to the upper and lower supports or by use of both the removable weights and springs. Resistance can also be adjusted by how much the pulley systems are compounded.
