I am sometimes not able to sleep at all, all night long. I just lay in bed and just don't get over that "step" of actual sleep. I just lay there with my eyes closed but I still voluntarily think about stuff etc... and it's so tiring and annoying and really depressing.
He just plants way too much in front off that low box. The length of the drop "should" be the same as the box height... that ensures a 45 degree plant and will prevent overreaching (too long) or underreaching (too short).
Where I'm getting at is that we underrate too much the importance of the vertical back that occurs in the high bar, front and overhead squat (where the overhead squat is the most restrictive of them all in terms of perfect form).
