@joeorsini I'm in similar situation at 70. If you can't lift 10 pounds, lift 5, 2.5 or even just your body weight. Anything helps stave off sarcopenia. I ride indoor bike as well. Not using the muscles will result in atrophy pretty quickly for folks in our condition. It becomes a vicious cycle. Also make sure you are getting enough protein in your diet. The new RDA's are a good place to start.
