An exercise device for use with a downwardly biased free bar (such as a barbell) having a pair of retractable support assemblies pivotally mounted on a pair of uprights adjacent which the bar is moved during exercise. Each of the support assemblies includes a pivoted bracket which is biased to its retracted position generally flush with the upright, but which is readily pivoted to its extended position supporting the bar when contacted by the bar as the bar is moved downwardly. |
