A teammate of mine pulled his hamstring. He has bene doing a lot of squatting and has gotten a lot stronger. Is it possible he pulled it do to lack of recovery from the squats?
I think if the squats are done with a high bar position, narrow stance and shallow depth than the squats could definitely be a contributing factor. On the other hand, I typically recommend very deep squats to increase hamstring-glute strength in extreme ranges of motion.
