ADJUSTABLE RESISTANCE EXERCISE DEVICE |
摘要 |
A resistance exercise device enables resistance training by using one or more retractable cables that provide resistance to the user when the user pulls on the cable(s). The resistance exercise device provides a retraction force to retract the cable(s), which is independent of a resistance force applied to the cable(s). The resistance exercise device may thus allow adjustment of the resistance force without affecting the retraction force.
