Tennis

So a common injury in tennis is tennis elbow. I've had it myself. It's absolutely the worst when you're trying to compete, but a great way to prevent it is to make sure you have good technique in your serving. You want to make sure when you come up on your snap that you're not using just your arm. It's a body motion. Get a good coach to practice that and make sure that you aren't ruining your game by serving improperly. Also make sure that you warm up your shoulder before you serve as it's really quick and easy to hurt your shoulder if you go out, come out of the gate serving hard. And then slowly build up from mostly second serves and your matches up to your hard first serves.
