leg press hits the qauds differently...i feel it in the top part of my quad...i feel squats throughout the whole leg..and leg extentions at the bottom...i like to hit it all...i love press after squats and squat deads...man i like to destroy the muscle...but thats me...your split looks great man...plus i like to do some heavy and something lighter...so if i do squats at around 8 reps per set...then i like to do squat deads for only a few reps...there isnt one and only way to workout...people are different...haha there are to many workout racists in this forum..haha
