Abstract
The present invention relates to a resistance type exercise device that uses frictional forces between members to provide resistance for a variety of different exercises. In operation, when a pull cord is withdrawn from the exercise device, a cord wheel converts the translational movement to rotational motion. A brake lever contacting a brake drum fixedly attached to the cord wheel provides a friction resistive force to the rotational motion. A recoil cord causes the recoil cord 900 to stretch and wrap around a bearing lug, placing the recoil cord in tension. The potential energy stored in the tensioned recoil cord is used to rewind the cord wheel and restore the pull cord back to its at rest position.
