A good physical condition is one of the requirements in playing ping pong and to become successful in it. While ping pong is not as physically strenuous as some activities, it does require you to be quick on your feet and  with your paddle. To help you improve your speed and keep you healthier all around, a typical exercise program with a daily activity will surely help you. If you are not playing, use that time to watch your opponents. Take a good look at how they play and what openings you can exploit in their game. Studying how they serve, how they return a serve and what are their strong and weak points will give you the winning edge, no matter how highly ranked they are.
