I agree with Valdez. There is nothing worse than seeing some delb throw 500 on the bar and then proceed to do quarter squats with it. I go ATF. It is the only way to get huge, thick quads. (And a large ass, I might add)

Anyone ever heard of "Breathing Squats"? Demon introduced me to them last week. You basically pick a weight you know you can only do about 10 times on a good day. Then, you do 20 reps with it. You can take as long as you need, the only rule is you can't rack it. I did 365 for my 20 and I felt it for days!
