Some may think tennis is a simple game. The players on either side of the net just hit a ball back and forth, right? Well, for those who actually know how to play tennis, they understand a lot more goes into the game than simply swatting a ball covered with felt.

Groundstrokes, drop shots and serve placement. Footwork for hammering the ball from the back line, familiarity with charging the net and fine-tuning for first-serve accuracy.
