ABSTRACT:
An accessory for weightlifting equipment that serves as a mechanical training partner for the weightlifter. The accessory is an electrically-powered, mechanically-driven device that provides a positive assist to enable the lifter to keep lifting even after muscle fatigue or failure. The accessory also provides a negative assist by applying more force as the weight is lowered. Both positive and negative assists are under full control of the lifter using foot or hand controls. The accessory also acts as a safety device which can control the weight if the lifter has problems or feels injured during a positive lift.
