It's not just about moving faster, it's about moving smarter. Martina Navratilova explains why she's a huge proponent of v-tennis, which is moving toward the ball in a "v" shape. With v-tennis, you can cut off the ball when it bounces instead of waiting for it to come to you.

Here are the key advantages of v-tennis:

1

You're closer to the net.

2

You're hitting the ball at the right height. 

3

You're taking time away from your opponent.

4

By cutting off the ball earlier, you actually don't have to move as far.
