I am 57 years old, dealing with Diabetes, trying to completely understand that. 5 years ago, I was working out 4-5 days a week, getting strong and then I hurt my Achilles tendon. 7 months later, when it no longer hurt and I could stretch it some, I had already lost 45lbs. Lost tons of muscle but my feet, Achilles, knees felt way better. I know have zero interest putting all that muscle/weight back on.
My goals now are to be more active every day. This year I have skied/snowboarded 10 days (1 day last year). I have been riding the MC at the track once a week (it had been 30 years since I had been on a real track). Golfing a bit more, walking the dog a couple days of week.................my goals are to mix it up, have fun, and just be active. Keep moving!
