Training the non-dominant side is important for all tennis players, including those who are 10 and under. In fact, it is especially important for young players to develop their non-dominant side as they are still in the process of developing their coordination, balance, and motor skills. Training the non-dominate side can dramatically improve balance and coordination, promote body symmetry, reduce risks of injury, enhance cognitive skills, boost confidence, and more.
Here are some specific benefits of adding some training to the non-dominant side for young tennis players:
Promotes Balanced Development
Young players who train their non-dominant side can promote the balanced development of their bodies. Tennis requires players to use their entire body, and training both sides can help to ensure that each side is developed equally. This can improve the player’s overall physical ability and help to prevent injuries caused by muscle imbalances.
Develops Motor Skills
Training the non-dominant side can help young players to develop their motor skills, including enhanced hand-eye coordination, timing, and footwork. These skills are essential for success in tennis, and by developing both sides of their body, young players can become more well-rounded and adaptable on the court.
Increases Confidence
As with older players, developing the non-dominant side can help to boost confidence in young players. By being able to hit a wider variety of shots and feeling more in control on the court, young players can feel more confident and motivated to continue practicing and improving their game.

Enhances Cognitive Development
Training the non-dominant side can also have cognitive benefits for young players. By challenging their brains to learn new skills and movements, young players can develop their cognitive function and improve their problem-solving skills. When they spend time on performing new skills on their non-dominant side, they are stimulating their brain to create new neural pathways and connections. This can lead to improvements in memory, attention, and a positive approach to problem-solving skills, which can benefit the player both on and off the court.
Overall, training the non-dominant side is just as important for young tennis players as it is for older players. By promoting balanced development, developing motor skills, increasing confidence, and enhancing cognitive development, young players who train their non-dominant side can have a significant advantage for success in tennis and beyond.
