First Claim
1. In a system employing a frame of the power rack type which may be used with a barbell that includes an assembly of weight plates on a weight lifting bar and which is of the type having:
- a plurality of uprights held in generally rectangular plan-relation as first and second pairs of uprights and each upright having vertically a generally uniform series of holes transversely therethrough, respective holes of the first pair of uprights being in horizontal alignment and respective holes of the second pair of uprights being in horizontal alignment, a first support rod mounted in a respective hole in at least one upright of said first pair of uprights, and a second support rod mounted in a hole in at least one upright of said second pair of uprights, the improvement comprising;
means adapting said system for use as a safety system in performace by a user of guided leg presses, guided bench-presses, guided standing-presses and the like, said means adapting including;
a slider system, means for holding said slider system between an upright of the first pair of uprights and an upright of the second pair of uprights, said slider system having means for adjustably securing said barbell in a horizontal position transverse to said first support rod and said second support rod with said barbell extending over and across said first support rod and said second support rod, said means holding the slider system permitting sliding of the slider system a distance upwardly from said first and second support rods, said means for holding the slider system including;
first and second guide shafts, means for fixing said first and second guide shafts in parallel-spaced relation between an upright of said first pair of uprights and an upright of said second pair of uprights, said frame having a forward portion and a rearward portion, said first and second guide shafts being adjacent to said rearward portion, the slider system further including a respective slider sleeve on said first and second guide shafts, a cross member joining the slider sleeves, and said means for adjustably securing comprising a respective flange extending in a fore-and-aft plane along the length of each slider sleeve.

Abstract
A system for weight lifting exercises provides the user with a guided leg press/multi-press that has a safety mechanism which is adjustably limitable to prevent a barbell, an assembly of weight plates on a weight lifting bar, from falling below a chosen height. A series of holes in uprights provide a range of adjustment for barbell support rods during guided bench-press and standing-press use on a slide assembly permit a plurality of barbells to be received at one time, thereby increasing the weight-load capacity of the slider system. A part of the system serves as a chin-up bar. Numerous exercises using the system may be performed. A supported barbell includes a pivotal foot-plate with angle limiting provision. A slider assembly may include a two-piece apertured flange for locking a barbell in place during an exercise.
