One of the key components for playing tennis is the ability to get to the ball in time to hit it. To be more precise you need to be able to get to the ball and be in position to hit it correctly. If you get there to late you will either hit the ball out ,or hit back a weak return that your opponent will easily put away.
In order to get to and hit tennis ball correctly you need to shuffle, your feet while keeping your body parallel to the net. This position will enable you to change directions in a instant and immediately be heading the opposite direction in a instant.
If you run when turning sideway to the net you will need to take least two steps to change direction and this will slow you down immensely so that you will be out of position for the next shot.
I will have some pics up on this in the future.
