Hello everyone, I am just a beginner. I am so tired to run around the court to collect the ball while I am practicing with my friend. That's why he advises me to buy a training ball which is tied with a 4 meter long rubber band on a weight. He says that would improve my hitting skill. Is here anyone might give me an idea about this product which is useful for a beginner or not. Thank you for help. Jermaine T.
