You must position your body in whats called the open stance to get optimium results from your shotmaking.If you turn your body sideways to the ball, you are lessing many aspects of good shotmaking. Swinging across your body, not leveraging your legs, bad balance, bad recovery after your short.There are so many reasons not to line up this way with your feet and body position.
The right stance, open stance allows you to recover quickly, have great balnce and use your legs well for power through your shot.(i forgot to mention when you hit open stance you basically face the net and hit the ball instead of facing to the rightif you are righty and lefty if you are a lefty on the forehand)
These are just a few of the reasons that you need to use open stance to optimize your shotmaking potential!
I will be discussing this more in my first book, Tennis Skills mastery!
