if i do sldl (with straight legs, as advised by bryan) with somewhat low weights, focusing on hamstrings, can i deadlift in the same workout? can i consider the sldl sets a warmup for the deadlift? bear in mind that i don't squat. i chose the leg press as my main quad developer because i can't go parallel in the squat without involving my lower back too much in the movement. that fact that i can move some serious poundage in the leg press doesn't help either, because i have to put plenty of weight on the bar to have the squat work my legs.
