Hitting walls make great practice partners to help develop your rally speed. Think of practicing in a mirror. Can you handle your own pace? It's all about developing consistent stroke production to enable a sustainable pace of ball exchange, or rally speed. Start at a close distance then gradually increase your distance from the wall. Begin with a goal of three successful strokes, then build from there. As you improve with practice, you will increase the duration and speed of your rallies and can reach a full court equivalent distance. Check out which local parks near you have a hitting wall (Note: Unfortunately, not all do). In the absence of a hitting wall, you can use a rebounder like the one below and set it up in your driveway or other suitable area. Brad Gilbert and Monica Seles were two of many touring pros who made use of hitting walls to improve and maintain their consistency. You're next!
