Forehand Volley Techniques and Tactics
Forehand Volley Tip #1
The most common reason why many tennis players hit a long forehand (outside balls) volley shots is because they tend to pivot their elbow or wrist when they hit the ball. If you do this, you have to execute the shot accurately to avoid error. Remember to keep your elbow and wrist firm when you execute your forehand volleys. You also have to punch out from your shoulder when you hit the ball.
Forehand Volley Tip #2
It is ideal to hit the forehand volleys when the ball is at net level or higher. To do this, you have to move forward to meet the ball.
Forehand Volley Tip #3
For better results, you have to keep your racket head above your wrist when you hit the ball.
Forehand Volley Tip #4
Always remember that in a backspin forehand volley, the ball floats farther than in a flat volley. Thus, you have to hit your ball lower and apply lesser power.
Forehand Volley Tip #5
To hit a proper forehand volley, the magnitude of the downward angle in your racket swing must be of equal proportion to the magnitude of the upward angle of your racket swing.
Forehand Volley Tip #6
Always move forward and meet the ball in front of you when you make contact. Avoid hitting the ball back or else it can cause a lot of errors.
Forehand Volley Tip #7
When you are moving forward to hit the ball (as mentioned above at contact), you have to make sure to that you keep moving when you are about to make contact with the ball.
Forehand Volley Tip #8
If you are about to hit a return from your opponent’s heavy topspin shot, you have to remember that the ball has the tendency to jump off from your racket face. Thus, you need to compensate this by hitting the ball a bit lower.
Forehand Volley Tip #9
If you are going to hit a forehand volley below the net, remember that it is ideal to hit hard and deep than on a high ball. Add backspin in your shot and for best results, hit a drop shot or angle forehand volley shot.
Forehand Volley Tip #10
To hit a backspin forehand volley, you have to tilt your racket face upward or do the downward chop.

Justine Henin reveals the secrets of use of non-dominant hand in one-handed backhand groundstrokes in her own words “if you do not use it, it’s really tough; if you use it, you feel perfect”. Understanding this perfect feeling will help you master one-handed backhand groundstroke technique. The important roles of non-dominant hand in one-handed backhand groundstrokes are:
1) Keep body in good balance.
2) Facilitate to use shoulder muscles other than forearm (it’s natural for our symmetric two hands/arms to do the same motion).
3) Prevent torso from overturning to lose control and consistency.
4) Act as a brake to stop body further turning so that arm and racquet continue to accelerate to reach max speed (whipping motion).
