ABSTRACT:
A device for assisting a lifter during exercise with a weighted bar including a pair of upwardly-mounted brackets for enclosing respective end portions of the bar. The brackets include a lower portion defining a narrow channel which centers the bar when the bar is lowered and further include an upper outwardly flared portion permitting natural movement by the lifter when raising the bar. A resilient lift assembly mounted in the channel provides a dynamic lift-restoring force to the bar in response to downward movement of the bar thereagainst for development of explosive muscle power of the lifter. The brackets include a ramp surface inclined toward the channel for self-spotting by the lifter.
