Abstract
The exercise apparatus comprises a frame and a carriage. A resistance system resists movement of the carriage with respect to the frame and the longitudinally headward direction. The resistance system allows the resistance to be changed at the head end portion of the frame and further does not require elastic members to travel with the carriage when they are not use. The rebound system that adjusts the range of motion of the carriage comprises two flexible members attached to the carriage and the frame and a resistance member is attached to a central portion of the flexible members and resists lateral seperation of the central portions of the flexible members.
