A Tip From Vinay Karia: TENNIS GROUNDSTROKES:
In order to hit great strokes you have to realize that you need to lift the ball up and over the net. As a coach, this is by far the most important thing to realize for almost every player I work with.
What do I mean by lifting the ball? It means a movement with the entire arm from low to high. It doesn’t matter if you are hitting a forehand, one-handed backhand or a two-handed backhand; the physics involved are the same. Almost all recreational players swing too horizontal on a rather straight line and not enough low to high. This results in many balls hit land in the net and it is probably the #1 mistake I see made on a tennis court.
The reason most players practice a swing which is too horizontal, is that they see their target through the net. Looking through the net you are actually in-line with your target on a downward sloping line, and people swing just that way. I am certain that people would miss a lot less if you couldn`t look through the net. Sometimes on television or in a drawing you can see these great animations where they show the flight path of the ball. Those lines always have a nice arc on it. In order to get that kind of flight path you need to lift the ball.
So next time you go out on the court, try lifting the ball more and feel free to exaggerate that movement in the beginning.
