Hand Cramping.

[Homer55]

When im rock climing my hard tends to cramp and i cant grip properly (not ideal when im 20' in the air). How can i stop this happening.. is there a sport drink that could help or some exercise.. ive been using something called a gripmaster which is helping my grip but not helping the cramps. Any suggestions?

you can try an isotonic or hypotonic sports drink, like lucozade.
