A weightlifting apparatus that supports a free weight barbell when
activated using two counter-weight controlled support arms that are
mechanically attached to a vertical support on a bench press system. The
vertical supports each have a slide rail that is mechanically coupled to
a locking assembly that acts to release the support arms using buttons.
The support arms are attached to independent counterweights or springs by
means of a cable. When released by a foot pedal these support arms are
elevated by the counterweights. The support arms hold the barbell and
prevent it from downward movement via the one-way locking assembly
mounted to the support arms. The support arms work independently of one
another so that a user may reset each support arm independently.
