Ok me and my coach just started working....again. We started bout 2 years ago and it was really busy so we decided to stop. Its $20 an hour and well ill just get to the point. He just want everything to be picture perfect. Hes making me switch my groundstrokes from open stance to closed and i dont feel comfortable because i feel unprepared for the next shot and also it feels as if im gonna trip. Hes a really good perfectionate coach but in a way is it right to develop you own individual strokes instead of being uniform. They work just as good as the open stance. He wants me to hop step and all of that and no offense no tennis player is thinking about that while playing. Their just trying to reach the tennis ball. What should i do?????
