"Where do my hands go?" and "How do I hold the racquet to return a serve?" are questions beginners often ask. So, that's why this racquet comes with a teaching grip plus some visual aids on the frame. We wanted to help kids put their hands in the right places on the handle and have the right attitude when they step out on the court. Cool, isn't it?MANOEUVRABILITY: Did you stop playing tennis when you were little because you found it too hard? Happily, things have now changed.
