I’m not a powerlifter and I don’t normally do box squats, so apologies if this is a really dumb question
One of my students (age 16, front row in rugby union) can squat to a good depth with a straight back, but he is leaning so far forward (like he is doing a good morning) that I have to come in each time to help him get back up (this is with very light weight)
As soon as I get him to do a box squat, he has absolutely no problems in staying upright.
So my question is, where is he weak? Or what else could be the cause of this
