Exercises need to be on the one hand hard enough to evoke a change at cellular level and easy enough to tap tap into the Parasympathetic nervous system. So how does exercise help?

In essence the nervous system builds the muscle instead of relying on the oestrogen. Different types of exercise stimulate this. HIIT (High Intensity Interval Training). Sprint interval training. HIRT (High Intensity Resistance Training).
