I'm trying to build up my legs because they are very lacking but I'm not sure how many sets to do for the entire thigh. Right now I'm doing:
Squat 5 sets
Extensions 4 sets
Leg curls 4 sets
Leg press or Hack squat 4 sets
Do I have the right amount of sets here for such a large muscle group? It seems backwards that I do the same amount of sets for thighs that I do for chest(15-18 sets) and I'm only doing 13 sets for the whole front of my thigh. If this isn't right, could you reccomend some other exercises that I could add in?
