Selecting a tennis court with a safe playing surface is another important step in starting your tennis program. Because your knees, hips and feet will take a pounding, surfaces that have some give-such as cushioned surfaces or even grass surfaces-are a better option than those made of concrete. Once you’ve selected an appropriate court, check it for trash, sand or other foreign objects. These unwelcome articles make it easy for you to lose your footing when practicing or playing.
