Hold a beach ball for stronger volleysTo hit consistent, effective volleys, you've got to meet the ball well out in front of your body with a smooth, compact stroke. Unfortunately, many club players make the mistake of keeping their elbows too close to their sides when assuming a volleying position. That brings the racquet in close and forces you to hit the shot from a cramped position. As a result, you lose a good deal of power and control. You can remedy the problem by imagining that you have a large beach ball tucked under your arms whenever you assume your volleying position. That will automatically bring your elbows forward and up, keeping your racquet in front of your body. It will allow you to meet the ball early and eliminate that weak, cramped volleying motion. You'll be making waves in no time.
hmmm. still no recommendation.
