When you include the weight of the tray, I leg press less than I squat
I usually just put on 2 plates a side, go down until I feel the hamstrings stretch, then push up until just before my leverage increase and back down, keeping it right there for 20-50 reps
Heavy weight and low reps, build big legs not
My legs were at their biggest when I competed in cycling lol, they have atrophied considerably in some areas, but the tear drop muscle is much bigger.
