When I was in my 20s and 30s I was very confident about my physical ability and strength, but when I became seriously ill, I started getting weaker and seeker..,upper body always less strength but that is typical for most women..as I learned in my self defense training. So legs are suppose to be our torte but I was the weakest in my class even in my lower body. Everything has gone down down down even with my joining a gym for years and working out 3 times a week. No matter what I did, or do, I just can't gain muscle but keep losing to where mt arms and legs look like sticks. Nearly 20 yrs ago my dr even tried adding testosterone to my bioidentical hormones....it jumped started my libido but no help with muscles and I started getting male pattern baldness so stopped that! I just think it is noteworthy that even when I use excersize machines and was using weights, my stamina and muscle just continues to decrease. I wonder if anyone else has noticed this. It discouraging that it doesn't improve, but I keep trying to excersize because they say if you don't use it, you lose it. I can understand being weaker now since I've been in bed with various illnesses for two years, but puzzling that excersize doesn't rebuild for me, and I eat a diet relatively high in protein.
