Tennis ball machines are used to improve your game but they don't do it by themselves. In order for the tennis ball machine to work in improving your game, you have to practice with it. You'll need to be committed to practicing with the machine and relearning the skills that you'll need if you want the machine to help you improve your game. The tennis ball machine is used to help you learn how to hit a variety of shots. Footwork: Having the machine throw some balls at your feet may seem easy but after a while, you'll notice that it's not as easy as it looks, and learning the skill of footwork will be required. Shots judgment: Being able to learn how hard or soft a shot has to be is another thing that can be practiced using the ball machine.  Serves & Returns: A good thing about practicing with the tennis ball machine is that it can help improve your serves and returns. The aiming aspect of these shots will have you start learning how to aim in certain ways like getting low on your feet while aiming for where your opponent's feet are placed as they position themselves to return your serve. Focus: Having this tool also helps out with another skill that's very important during a match, which is keeping your focus on what's happening. Keeping yourself focused can help out a lot of ways because it means you're not worried about things like the score or even how tired you are so long as you're aware anytime an opponent gets close enough to hit one at you or when you're on offense and need to get ready for a return. Timing: A tennis ball machine also gives players a way to work on timing so they can get ready for an opponent's return or in case they need to hit one on their own too. Different Angles: Using the tennis ball machine is also very good for learning how to hit from different spots on the court.
