Abstract

A weight lifting station including a pair of guide posts for guiding a barbell assembly in a vertical direction. The barbell assembly includes a weight bar, a sleeve telescoped over the weight bar and stops attached to the sleeve with catch pins to restrain the stops in any one of three conditions of orientation. In one condition, the catch pins lock the stops in engagement with apertures in the posts thereby preventing vertical movement of the bar from a selected vertical position. In another condition, the catch pins lock the stops in a position disengaged and remote from the apertures permitting the barbell assembly to slide vertically on the guide posts. In the third condition, a user may manually rotate the sleeve, throughout a small range limited by the catch pins from a position where the stops are fully engaged with the apertures to a position where the stops are withdrawn from the apertures therby providing the user with a self spotting capability.
