Keeping fit after 50 is definitely a challenge. Been going to the gym almost daily and changed my eating habits. I've lost 57 pounds since July 2019. Feeling better than I have in years and now I'm just working on maintaining.
I have not exercised since Highschool. Last December I found out I was Diabetic. Spent 4 days in PCU. Scared me - went on strict diet and started exercising. Tuesday I turned 50. Have put on 15 lbs of lean muscle and my blood sugar is in normal range almost every day.
