Personal Coach: Tennis

I've played tennis since I was big enough to swing a racket―I started banging a ball against the basement wall when I was three years old. Almost four decades later, I'm still playing―and loving―the game. It's a sport that gives me the level of fitness, good health, and challenge I value.

I've coached some of the world's best players, including Andre Agassi, but I believe you don't have to be a great athlete to play tennis. With a little instruction, practice, and patience, you can master the basics. Sneakers, a racket, and a can of balls are all it takes to get started. Many communities have beautiful public courts where you can play with a friend. Joining a private tennis club is another option. Either way, you'll have fun and get in great shape. And the friends you'll make are special because tennis is a social game. Singles, doubles, mixed doubles, parent and child, husband and wife, and leagues and tournaments offer recreational opportunities that can last a lifetime.

Busy schedule? Tennis is time-efficient, too. Even now, I'll grab a racket and hit against the wall at my tennis court for 30 minutes for a quick, fun workout. In fact, it's more than fun. In my opinion, hitting the ball correctly is a thing of beauty.
