TweetI used to do them a lot and I noticed great strength gains in my regular squats from performing box squats. The only probelm I had with the movement is that it would sometimes put some strain on my groin.

Tweeti used to but they really hurt my knees

TweetThey almost destroyed my back. This was back in HS, but when I got away from them my back problems went away. I think they make you stay too upright and not get you upper body down into position. I have a long torso so it's better for me to roll the bar down my back to about mid traps and then squat and that's too hard with a box.

TweetI do them alot. With good form, they're awesome but too many times people don't sit back far enough and place too much stress on the knees or sit back too far/don't keep their body tight and in position and end up falling the last couple of inches onto the box. I generally go a couple of inches below parallel alternating between close stance and wide and once in a while I'll go a couple of inches above parallel against bands just to overload.

Tweeti've done them a couple times. its very important to sit all the way back and explode up using your hips/quads. takes a bit to get used to, i like em though.

TweetI do them in my rotation (so once every three weeks). If I go too wide they bother my hips.SC1
