Do you carry a water bottle? Ok, when was the last time you finished the whole thing? If this isn't working for you, buy a big one liter bottle and finish it today. The single most effective way to instant performance enhancement at your next workout is to drink water. Barring you haven't eaten fast food for lunch, I promise you will feel better at your next workout "if" you are adequately hydrated.
The chances are - if you're doubled over like GRANT (above) - you may be dehydrated!
