Abstract: This is an automatic locking exercise device that incorporates a one-way locking mechanism. The device includes a frame, which supports a track, preferably a pair of linear bearing rods one on each side. A guide member, or linear bearing runs on each bearing rod and is attached to a handle or bar that is grasped by a user. A one-way lock is used to provide movement of the bar along the track in an upward direction but opposes movement down. In the preferred embodiment, rotating the bar actuates a lock release. This disengages the one-way lock and enables the bar to move freely up and down along the track. If the user ever drops the weight the one-way lock automatically engages and catches the weight. Explosive power training can also be performed on the device in that the user can safely throw the weight, knowing that the weight will be automatically caught at its highest point without risk of injuring someone.
