I actually love high volume so i split up hams and quads. I do about 20+ sets for hams and quads. Calves are done 2-3 times a week for me. For quads i will do leg ext, squat( either smith or free weight), hack squats, then a machine squat, then finish with leg ext again. For hams i do lying leg curls, seated leg curls, single legs curls, lunges, then finish with deads. And the reps go anywhere for 25 sometimes all the way down to 6-8. high volume wont kill you.
