Speaking of legs and STS... I have a squat rack, and am by no means some super body builder chic. My legs are the strongest part of me and I enjoy lifting quite heavy with legs though. Would there be any use for a leg sled machine or hack squat/leg press with STS? I am assuming that since the DVDs will not show one, plenty can be accomplished without one, just by using the squat rack and barbell. Mostly, I need somebody to talk me out of one I think
