I was wondering, whats the difference between an olympic squat rack used to train professional olympic lifters, and other racks like body solid, powertec, or the efs rack? I including a picture of the olympic squat rack, could you still bench in it? Im just wondering because in the pic the bar is on the outside, and I want to be safe because I have dropped the bar quite a few times. Also is this a better option then getting other racks? I like how its small, but Im not sure if its as good. This rack is going for pretty cheap in craigslist so Im just wondering, im kind of cheap.
