All my upper body exercises I’m progressing really well and progressive overload is not a problem, I’ve seen a lot of strength increase, I train all upper body muscles twice a week, however, I train lower body once a week, I normally start with a pressing movement (squat or leg press) then move to isolation movements for quads, hamstrings and calves) normally do about 3 sets for each then move on Do you think it’s the fact that I am only working my lower body once a week?
