Extreme Endurance
I'm always skeptical when it comes to promoting supplements, because I know that these products are usually heavily hyped, poorly supported by scientific research, and manufactured under less-than-ideal circumstances. It's kind of like bathtub gin - you never know what you're going to get, but you assume that it is what the label says. Sadly, that's not always the case.
But with Extreme Endurance, I think I've found a product that is WADA and IOC approved, and actually does what it claims. The product is basically an alkalizer - it keeps the body's PH neutralized when lactic acid generation outpaces the body's ability to process it and recycle it in to fuel. It also saves the muscles from damage to some extent. My own anecdotal evidence is that it works, and in a race or rally, it's worth about 8 minutes of extra effort. Those 8 minutes can be the difference between finishing strong, or finishing with the rest of the pack. In training, it will help you recover more quickly, thus enabling you to either raise your functional threshold wattage, or perform more anaerobic intervals than you might have been able to do otherwise.
Sample packets are available if you want to try them out, and just click on the link to purchase your own. Don't forget to use "coach" when you get to the promotion code part.
