A client complains to you that their arms dont seem to be hypertrophy with training they explain to you they complete the following program unfailingly?

Answer 1

I think I understand the question-

Sometimes certain muscle groups in our body are resistive to hypertrophy. This can be attributed to genetics, or also hitting plateaus or resistance points in training. It could also be diet.

Of course eat plenty of protein and try changing routine- more weight, less reps. Also lots of stretching.
