I used to be a major gym rat. That was when I was younger and wanted to be beautiful. I did high impact aerobics, followed by weight machines. It worked. I was beautiful.
No I’m 68 and beauty is kind of beside the point. I gave up my car about a dozen years ago and bike everywhere, providing incidental exercise. My ass is beautiful but that’s it. In the article that led me here you said you did 20 push ups. I’m impressed. Seriously. I can’t do 20 push ups any more than I can fly.
