I split my leg workouts into two days. Day 1 is Quads and Calves. Day 2 is Hamstrings
For Day 1 I do the following: Squats (most important), Power Clean, Leg Press, Leg Extensions, and some basic Calves exercise.
Day 2: Lying Leg curl, sitting leg curl, and good mornings.
I do 3 sets of about 6-8 repetitions. That's it.
