Go for it, Scott! When I was losing down to 115, I was always so tired and weak and my skin just hung from me horribly. When I learned I have osteoporosis, it Got my attention, and I decided I was not going to just waste away. It helps that my daughter and SIL are bodybuilders so they are coaching me, but what really helps is a friend of mine who is my workout buddy. We encourage and motivate each other especially on days when either of us is just 'too tired.' I have never liked to exercise and hate to sweat. Since my DS, I don't sweat anymore and somehow my daily weight lifting is not a dreaded time of day. I actually look forward to it most days. My energy, posture, and muscle tone have improved markedly. I don't do cardio as I don't want to burn calories and really have very little fat left, so am focusing on building lean muscle. Never in my life did I think I would be saying these things. I look at it as Part 2 of my body renovation. Just wish I hadn't waited till I was 63. Guess it's better late than never, right?
