Really simple tip: Drink more, especially around your workouts. The difference for me is always night and day when I make an effort to drink more. I’ve blogged about this before, but I fell off the gallon-a-day wagon when I started reading about the dangers of BPA and was subsequently unable to find a BPA-free gallon jug. I’ve started again in the past couple days and my overall mood and exercise endurance have improved dramatically. I think the real brilliance of Biotest supplements (I haven’t taken any, so I can’t attest to their quality or effectiveness) is that they require you to drink a crapton of water to follow their protocol appropriately. Most people I come across on a day-to-day basis are marginally dehydrated and benefit significantly from drinking more, especially around their workouts. It also helps to drink a ton with your post-workout meal. The process of breaking chemical bonds is called hydrolysis (literally, “to cut with water”), and my subjective experience tells me that I digest things much better when I drink at least a liter of water with a large carb-based meal. Drink more water. Not exciting or sexy, but effective.
