On the forehand side, a late contact point and failure to use the upper-body rotation to supply power puts tremendous stress on the racket arm (figure 11.3a). At the point of impact, your racket hand and arm should be even with your front foot, using a square stance. There is about a 45-degree angle between the shoulder of your racket arm and the contact point, which provides leverage against the oncoming ball. A late contact point, which might be anywhere from your belt buckle to your back, puts your arm in a weak position. Trying to use your arm to muscle the shot rather than rotating your shoulders and hips into the shot magnifies the stress on your arm. The solution for a late contact point is to prepare earlier, begin your forward swing a bit earlier, and aim for contact in line with your front foot. As your racket moves forward, allow your hips and upper body to rotate naturally to follow your racket and generate racket speed (figure 11.3b).
