Thanks for the replies. The trainer that I talked to has been extremely helpful. This was the only bit of advice that I disagreed w/ him on. I wanted to run it by other ppl to get their opinions.
Whenever I go heavy on squats, my first set is good, but I get winded pretty easily. I'll rest until I'm ready for my next set (around 5 minutes). The second set is when I feel my form starts breaking down. I usually fail to get my targeted # of reps. For my third and final set, I take it down to a weight where I can achieve my target reps with good form.
Bignate, how do I check my adductors for flexibility?
Citruscide, how wide should my stance be? I've widened my stance, but if I widen it too much, it gets really uncomfortable and I feel off-balance.
Tarheel, I have always thought about doing box squats, but nobody at my gym does them, so I can't ask anyone if I'm doing them correctly. Plus the only thing I could think of to use as a box is a bench, but I don't think it gives me good depth since I'm short (5'5").
