Abstract

A resistance apparatus for use in performing squat exercises, in which a belt-type device is worn by a person for providing a resistance connection between the person's legs. The resistance apparatus includes a chain, which is connectable at one end to a connection arrangement associated with the belt-type device. The other end of the chain is connected to a stack of weights or any other satisfactory resistance-providing device, with the chain being trained around a series of pulleys. A tracking arrangement provides front-to-rear movement of the chain at a point below the connection of the chain to the belt-type device for maintaining the resistance directly below the person's center of gravity as the person moves in a front-to-rear direction during performance of a squat exercise.
