Abstract: A device for adjustably suspending a pair of gymnastic rings or handles is described. The device has a power spring to automatically retract a pair of straps attached to the rings onto a spool. There is a lock mechanism that holds the pair of straps and rings in place at a desired height. A release cord is attached to the lock mechanism to allow for the release of the lock mechanism from below. A strap retrieval cord may optionally be attached to a strap to allow retrieval of the pair of straps from below.

Abstract: 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.
