I will be 77 in three weeks. I walk a mile twice a day every day. It seems to help a lot with the fatigue. I did physical therapy for 4 months after having my knee replaced. I’ve had noticeable muscle building, even though I’ve been on Lupron for eight years and my testosterone is extremely low. I started going to the gym three times a week and having a personal trainer work with me once a week, I do exercises the whole time and really don’t take breaks for more than a minute or two in the hour I am there. I’ve had noticeable muscle building occurring, I am able to lift more weight, And do exercises with higher weights with my arms and my legs.

You can rebuild your muscles even with low testosterone and in the late 70’s. You just have to be determined to ignore your fatigue, and it seems to reduce with exercise. You should see how much sweat I have when I’m doing these exercises just dripping off my forehead. Low Testosterone sure brings up the sweat when you’re exercising a lot, bring a towel.
