I wanted to encourage anyone over 50. A couple of years ago, I gained several pounds of muscle but was not lifting on a regular basis. What I was doing was hiking for 45 minutes daily with a weighted vest. My doctor said there was some research supporting that as an outcome. I’ve kept that in my cardio routine a few times a week. If you decide to do this, start with no more than 10% of your body weight and work up from there.
