Hi everyone, I am trying to gain muscle mass particularly in my legs and butt area so am doing sets of squats, lunges, and other exercises for these areas. The trouble is I don't know if I am working on my glutes effectively as I even after performing the exercises to exhaustion I will feel muscle fatique in my legs the next day but not in the glutes. Are there any tips on how to properly isolate this area as when doing squats, lunges, etc I can only really feel the burn in my quads. Any advice is much appreciated.
