Just wondering Eric, what sort of education do you have? You seem to have your anatomy and kinematics of the body down pat so I'm assuming you do something related. Physiotherapist? If you don't mind me asking that is. I tried some of those squat tips as I have some of the same problems of rounding out a little bit at the bottom. They work!

BTW, Marv don't be insulted by his criticisms, I dont' think I've seen an occaision where he hasn't had at least a page of writing on any vid posted. lol You're doing awesome man.
