Well, of course the obvious bigger body exercises like squats, (maybe more close stance or oly HB) also front squats hits the quads more along with leg pressing and onto more iso work like extensions. I have heard hack squats, but they make my knee caps feel like they are going to shoot thru the wall into the women's locker room. I never do those or extensions personally. Most pulling, like deads or their kin ie: RDL's SLDL's, GM's, pulll throughs, GHR's, leg curls, hit the hamstrings and glutes.
Eating enough will add size too, as the bigger compound exercises to develop the legs, can take quite a bit out of the body, so more healthy food may be needed.
