Draw a sword from your hip for better backhand
The backhand gives average players more trouble than just about any other stroke in tennis. If you were to line up 10 club players and ask them all to hit a backhand, you'd likely see 10 different strokes. Most players run into trouble on the backhand side because they start the stroke with the racquet too far from their bodies. As a result, they can only flail at the ball with their arms, and their backhands usually are weak and unpredictable. Instead, think about drawing a sword from your hip when you hit the backhand. Turn sideways, reach across your body and draw the sword in a smooth, even motion. This will not only help you keep your arm in close to your body, but also will aid in honing the proper low-to-high topspin stroking motion that will give your backhand the cutting edge.
