I have been in this boat several times, and the battle does not get any easier as I get older. At 43 it is much harder to lose the fat then it was just ten years ago. This time I started at my highest weight ever of 220 on my 5'9" frame. I felt like a slug, what made matters worse was that in April I had my gallbladder removed and under doctors orders, could not lift anything over ten pounds. I started by walking on the treadmill at the gym since that was all I was approved to do. Since them I have gotten my weight down to 202, but I'll tell you the first hill ride I did just about killed me just a month ago. This last weekend I took my mountain bike for a road ride on 14 miles in just less then a hour and felt like I could go for another hour. So, don't give up, everyone has been there too.
