Appreciate the comments from cubsfan, bluegold on lifting/exercising. It is inspirational. Another to add - incorporate meditation and/or breathing along with yoga. Exercise your brain and maintain flexibility. I am not in the 50s but in much better shape now -- I do P90x, Insanity, weightlifting, cardio, 15 minutes of meditation and 2 days of yoga. These activities along with time with family/friends and reading round out my top three. Hoping I am not a couch potato in my 70s.
