How can I practice playing tennis?

I'm sorry Rosey, but you are wrong. it is actually bad for your footwork. Firstly I would go and find a good tennis club with a good coach who knows alot about good techniques and you will feel that you will progress quickly. Try to take quicker shorter steps to help you keep balance and not big hard steps and dont forget to keep light on your feet.It is actually good to practise your vollying against your brick wall but try to go out and find a local club and play compitition on the weekends.
