If you play tennis, you may be familiar with the different racket customizing choices you have -- common choices include string type, gauge and tension. Not so common is an inexpensive device called a shock absorber or vibration dampener. These devices have no impact on your performance, but some players can't play without one. It's a personal choice, and if you do use a dampener, its placement must comply with the rules of the International Tennis Federation.
Exercises for Tennis. Exercises that increase your rotational power increase swing speed and enable you to blast ground strokes and serves past your opponents. Use medicine ball drills for rotational power. Most are sport-specific, mimicking movements of the tennis swing. They include overhead slams and rotational throws with a closed or open stance -- an open stance mimics the open stance used for serves and returns. Moving medicine ball catches and throws allow you to mimic forehand and backhand swing motions.
