Re: Training Quads and Hamstrings seperate
If you can do them at your gym I'd try hamstring raises or glute-ham raises, in addition to some form of deadlift (doesn't necessarily have to be SLDLs) and leg curls. But you don't actally have to do more than two exercises, or even more than one, so long as you get in the weekly volume you need (you can also just train more often).
I'm currently training hamstrings on back day, I do trap bar dedlifts and just do a few sets of leg curls to finish them off. I do this 3x in two weeks and in between they get worked again somewhat when I squat for quads.
