Are you serious? That's the EASIEST part of the rep. The hardest part is when your ass hits the floor and you pause at the bottom and drive up past parallel. THAT'S the hardest part and it's how all squats should be done for bodybuilding purposes.
Big J,
I agree with you that when your upper leg makes an acute angle with your lower leg, the squat is most difficult. You are at a mechanical disadvantage certainly. But do you need to do that to make your upper legs grow? If you do reps as in the video, without locking out, or not locking out very long, you build up a tremendous amount of lactate in your quads. Does that make your muscles grow?
I had Per Tesch's book, target Training some years ago, and I recall that some of the MRI pictures showed much different effected muscles than you'd think when doing particular arm or leg movements. So the question I have is: Do you really have to go that deep in a squat to make it work for leg development?
I have attached a pic of Tom Platz and Fred Hatfield in about the deepest squat position you can get (no ass on the floor though:)). Fred was strong as hell, but his legs were nothing like Platz's.
