ABSTRACT:
The present invention relates to a progressive accommodating resistance exercise device including a retractable cable, resistance means for providing a resistance force opposing extension of the cable such that the resistance force is a function of the speed of cable extension for all resistance forces having a magnitude greater than the fixed cable retraction force, and adjustment means for varying the relationship between the resistance force and the speed of cable extension for all resistance forces greater in magnitude that the fixed cable retraction force. Means are also disclosed for minimizing the likelihood of joint hyperextension during use.
