As we really enjoy this hot summer, our training sessions in the Dojo can become quite tough sometimes. Especially when the thermometer climbs up towards 30°. But as I say, stop moaning, what shall all those Jiujitsukas say they live in countries, where it is always hot as now here just over the summer?
So as we train more or less the same way than on ordinary days, the body needs definite more liquid to drink. And here the best you can do is, just drink clear plain water. Bring a bottle of water or use the tap water in the hall. You do not need any so called energy drinks or special designed "sport drinks" They are useless and only suck your money. Cheers water!
