During intense training, don't just "hit the wall" with muscle burn and pain - blast through it with Extreme Endurance, a revolutionary athletic performance formula. It's clinically proven to reduce lactic acid by 15% and increase aerobic threshold by double digits.
Extreme Endurance is a revolutionary athletic performance formula created by athletes for athletes. This formula has a Published, Gold-Standard, third party, double-blind, placebo-controlled, crossover study backing up claims of 15% reduction in lactic acid and a double digit increase in aerobic threshold. Many companies make claims on individual ingredients but Extreme Endurance has a published study on the formula itself. Each batch of Extreme Endurance is tested to ensure that it is not contaminated with banned substances to provide additional reassurance for elite athletes.
Extreme Endurance is able to safely buffer the hydrogen ions (H+) acid in lactic acid with powerful buffers. In addition, Extreme Endurance adds second generation ingredients to its formula to address other biochemical changes that occur to an athlete's body during intense exercise, such as tissue damage, oxidative stress, suppression of the immune system and harmful inflammation. These added ingredients are:
Papain, a protease enzyme derived from Papaya, which is a powerful anti-inflammatory that helps repair and rebuild muscle tissue and relieves muscle soreness.
Catechins are added and are one of the most powerful antioxidants to help fight oxidative stress during exercise.
Electrolytes complete this revolutionary formula to assist athletes with the ability to quickly recover and restore balance and maintain the competitive edge.

I've used Xendurance for a couple of years now on my run up to Challenge Roth Ironman and recently 2014 London Marathon. I've also done a couple of events in between without it to experiment and there is no doubt that it aids recovery and reduces stiffness in my muscles. I will not do another endurance event and its build up without it. Its a must in my training plan. I can go out and ride for 6 hours on a Saturday knowing that I'll be able to do a half marathon or longer on Sunday. Fitting training in during the week and getting up for work is always a challenge but with Xendurance I don't have the same fatigue at work so its not a bother.
When I first heard of this product on the IM Talk podcast I wrote to John and Bevan and asked what were they up to. But I decided to give it a try myself and was very surprised that what in essence seemed to be the ingredients of an anti-acid tablet could make a difference. I've actually spoken to the Xendurance team in the US and put this question to them, the secret seems to be that the acid lowering ingredients pass through the stomach and into the lower intestine so the acid reducing ingredients get into the blood stream. Science aside, the stuff works and you'll soon find that you can train harder and more consistently when you eliminate the DOMS from harder sessions. I've tried all the xendurance products, this is the one I never let run out of stock!
Started using Xendurance at the start of the year and noticed the difference in the first week. Did a 5k before taking them and then again the following week after starting on them. Less leg pain and less overall fatigue. I have continued now for 3 months and loving the consistency I can apply to the training as day after pain and fatigue is reduced. Can't wait for race season. Bonus that they have 10% off here.
