I agree somewhere in an hour before your workout. Training takes place more vigorously and, judging from the heart rate monitor, calories expended more. Once it is taken directly before a workout, and the heart nearly broke through the ears and not jump right somewhere in the brain racing. )) Losing weight is, the control jeans dumped on the go, and the rest of the pants hang on the hips. But this, I think, still more merit fiznarguzki and diet. Yes, during the actual workout drink only water, without there energy supplements.
