Tennis, soccer, volleyball? Or maybe some jump rope and a quick jog? If there's anything celebrities need to know how to do well, it's staying in shape. And that's why you see Brit Brit playing tennis, Paris riding her bike, Matthew or Lindsay out running and TomKat hitting the ball around. To look good you need to feel good, so why not have some fun in the process? No sense in hanging around the weight room all day!
