Did you say taking notes? Good lord man, MONSTER DELUSIONS. Before you start griping, I was taught more or less perfect form by my best friend who is a physical therapy assistant, and TRUST me your form is terrible. Forced reps on leg extensions?! Followed by SMITH MACHINE squats? Have you and your knees always hated each other, or what? I hate to knock a brother, but you put a video out there, expect some criticism.
I 'd love to hear from you what the fook is wrong with leg extension with some forced reps, then going to smith machine squats.

Although I agree his form is not the best, to say the least - hey! the guy himself admmited that, but if it works for him and he's injury free, more power to him - I can't say what's wrong with these 2 exercises. Forced reps on leg extensions works wonders, they are truly friers on the thighs.
Re smith squats, EVERY bodybuilder on earth regularly does it / does it from time to time. That's nothing wrong with that exercise. Although I prefer free squats, smith machine squats give a nice change of pace with a lot of muscle stimmulation. Even Ronnie Coleman does it from time to time - whatch that DVD he filmed with Tony Doherty following the '05 O, in Australia.
