How often should I string my racket?
Just because your strings haven't broken it doesn't mean you shouldn't get your racket freshly strung.
JFC-TENNIS suggests that you first determine how many times per week you play tennis...
The number of times you play per week should equal the number of times you have your racket re-strung each year.
For example, if you generally play three times a week then you should have your racket re-strung three times per year.
