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:
You're closer to the net.
You're hitting the ball at the right height.
You're taking time away from your opponent.
By cutting off the ball earlier, you actually don't have to move as far.
