Hi all, winter is coming and unfortunately this means the end of tennis season in Belgium. I will be spending much less time on the court, only 1h/week to 2h/week. Playing tennis indoor is quite expensive in winter unfortunately. But of course, we do not need to be on the tennis court to improve ourselves. Many things can also be done off court, so I was wondering what you do to improve when you are not able to go on court so much.
