I'm 53, 5'10"/ 146 pounds and have been on a transition level estrogen HRT regimen since January 2010. I gave up pushups 15 years ago because they were hurting my wrists so I'm a little out of practice. That said, I just came in from push mowing the yard, saw the thread and dropped down on the floor to give you twenty (LOL, not claps).
I have taken to yoga for my back since I retired, can press into wheel, jump to crow, do arm balances, and 60 second hand stands. I have been scrawny for my entire life. People have always marveled at my strength and HRT has not effected it. My physical ability comes from the mind, not the muscle, years of self discipline and meditation.
