Try 1-2 sets all-out of 20 rep breathing squats. Do not compromise depth, squat as deeply as you can without orthopedic pain, don't worry about the ego. Follow these up with stiff-legged deadlifts on a slightly elevated surface for ~10-12 rep sets.
IF you give 100%, I can guarantee that you won't want to do it more than twice in a week. Forget doing legs every workout, if you can do any bodypart every workout, how hard do you think you've worked it?
Diet will be just as or more important than the program itself. You must have a surplus of quality calories to grow. I know, as I have avg genetics and years of squatting helped me add 50 SOLID pounds of bodyweight over the course of 8-10 yrs, with a 405x23 A2G squat and 640 max squat below parallel at 215# bwt. Good luck, can't say it'll be fun though!
