I should also point out the Ed did many many sets of assistance exercises, stuff like leg press and leg curls, so his 3 sets of squats was not all he did, which some might think reading Adams post.
My guys finished their 3 sets of squats 20 minutes into the session, I'm sure Ed trained longer than that.
Instead of doing assistance work for the squat, we do more squats.
We do PPP for bench, but twice a week, with lots of assistance work, but the deadlifts will pretty much look like Ed's.
So I'm not second guessing Ed's program, I'm simply adjusting it to suit our training on the squats. I see limited benefits in leg press, extensions and curls, plus I dont have/want that equipment at PTC.
