A couple weeks ago I began to get frustrated at the halted progress my legs were (or weren't) making even though I was squatting heavy and increasing the volume of sets to 8 and trying all sorts of different things and just not feeling like anything was working. Well, a couple of weeks ago I started doing something different.
I began doing 5 sets of 20 reps with 135 (Not increasing the weight as I have done in the past). Within each set, I've been changing my stance after 10 reps, so for the first 10 reps I stand with my feet wide and toes slightly pointed outward, and for the latter 10 reps of my set I bring my feet closer together (0 degrees, shoulder width). I figure "with such light weight, why not front squat?" So, I have been doing this for a few weeks and my legs are not only getting more massive but I am seeing more definition, and doing extra straight leg deadlifts (because front squats seem to leave something lacking for me in the hamstring area) my deadlift has gotten stronger. Definitely a valuable tool.
