A new quarter is coming up at school and I'm getting my friend to join me in the gym.
I took him there today for the first time, to show him around and teach him some lifts.
One of the major difficulties I encountered was that he does not have the flexibility to squat at all. He can only bodyweight squat to where his knee is at a ~100 degree angle. If he tries to go any lower he gets off his heels into a strange stance...
Are there any methods or stretches that he can do to gain the flexibility to squat properly?
