After taking a 30 year break, I have recently taken up tennis again at the age of 55. Problem is, as the years passed, I have slowly added some extra weight. So, in addition to being 30 years older, I am also 30 pounds heavier. When I was younger, it was not very difficult to shed a few pounds when I needed to. Just cut back on the calories and ramp up the workouts for a few weeks, and the pounds melted away. Much to my dismay, I have discovered that is not the case anymore. Every extra ounce hangs on like grim death. I know I have to work harder, but I have also discovered that I take longer to recover, which makes it very difficult to add any extra workouts. I am currently playing tennis four times a week - two group lessons followed by some short doubles matches orchestrated by the instructor, and two "friendly" singles matches with a buddy of mine. I am also doing a full-body weight training session twice a week followed by some cardio intervals. Still, after several months, I have lost very little weight, and I am still moving around the court like a wounded water buffalo. Any advice on how to get out of this rut would be greatly appreciated.
