Quick one for you, I, like many people, used to get a really painful racquet hand through gripping tightly for the length of the game, so.....

Top Tip:

Buy an extra grip and wind it around the old grip, so you have one on top of the other. This increases the circumference of the grip, which means you are exerting your muscles and tendons through less distance, which means you use less energy.... its easier on your hand

Worked for me, although it might only work with people with big hands...

I was talking about squash last night with a friend and he came up with another tip for stopping cramping racquet hands.......

Top Tip:

Wear a sweatband on the wrist of your racquet hand, this will stop the sweat from your arm running onto the handle and making it slippery. When its slippery, you have to grip harder and that increases your chance of painful cramps

The headband is optional, it looks good on some looks very dodgy on others!!
