How many sets are good for squatting? Usually I do about 4 sets, but lately, when I'm finished, I don't really feel like my legs got a really good pump. (I can still walk easily ya know) My last two sets are very close to failure, so it's not like I'm only doing a little bit of weight. I get really good pumps from leg press, but I want squat to be my main leg building exercise. How many sets do you guys usually do?
