Abstract

A device which promotes concentric muscle development by automatically rendering assistance to a weightlifter who is experiencing muscle fatigue. The device contains a motor driven cable which can be connected to either a barbell or dumbbells. The device does not affect the weightlifter when not activated, and is activated when the weightlifter lifts the weight slower than a pre-programmed velocity limit. In addition the device functions as a safety apparatus in that it slows the downward travel of a weight which has exceeded a pre-programmed velocity limit.
