The whole rational being that I was refering to Barbell Hack Squat's. The subject of anything else was not brought up by me. Never explored any ratio difference concerning machines, angles, better design, etc because I did not mention Hack machines (who's ever brand/style) at all. Again, for the English challenged, it was the BARBELL HACK SQUAT that was the subject of my thought. The Pumpster again is confused or so bent on making someone else look bad that he (with ease) makes a fool of himself. Too bad, I'm sure he can be a plesant enought little chap if he really want's to be. As a act of kindness I might suggest he read "Body Building For Dummie's... 101".
If Beener get's so exhausted by a little reading than let me help him. Think of the BB Hack Squat as somewhat like a reverse Dead Lift, where the Olympic (usually) bar is resting on the floor, behind the lifter. More leg and less lower back is involved in the lift. Because the bar is more inline with the the body that the regular DL . Also the upper back and traps are involved with the exercise, similar to the regular DL. With best wishes, Good Luck.
