Tennis can be a frustrating sport, so if you are a newcomer, don’t expect too much from your performance too soon.
There are plenty of rackets to choose from, with the standard particularly good, even at the lower end of the scale. Rackets for beginners and junior-sized rackets are relatively inexpensive, but don’t just go for the cheapest — choose one that matches your body and grip size. Ask for advice from the sales assistant.
Don’t assume that once a string has broken the racket is no good and should be thrown away. If it is a good one, it may be worth having it re-strung and having the tension adjusted to suit your play.
