Abstract:

An exercising device for a barbell which increases the weight of the barbell during a first eccentric movement and decreases the total weight of the barbell during concentric movement. The exercising device includes a vertically elongated stand having a flat base at its lower end and a hook at its upper end. The hook is pivotal between a first position in which the hook extends around and attaches the stand to end of the barbell, and a second position in which the hook pivots away from the barbell and detaches the stand from the barbell. A weight urges the hook towards its second position so that the hook automatically moves to its second position when the base engages the ground surface. Weights are selectively added to the base to increase the overall weight of the barbell during eccentric movement as desired.
