To improve your basketball handles at home, there are various exercises and drills you can practice. One effective method is to use a tennis ball or a small rubber ball to work on your hand-eye coordination and quick reflexes. Start by dribbling the ball with one hand, then switch to the other hand while maintaining control and speed. You can also incorporate stationary dribbling drills such as figure 8s or around-the-legs crossovers to enhance your ball handling skills. Additionally, watching instructional videos and tutorials online can provide valuable insights and tips on improving basketball handles.
