It Works!

I am a newer CrossFit member but sometimes bike and run. I started Extreme Endurance 3 weeks leading up to a sprint triathlon. With little training I somehow pulled off 1st AG and 20th female overall. I’m a believer!

Hi Joyce,

Great job! Congratulations on your success!

Ran almost 2 minutes faster this year on the same course I ran a year ago. Thanks!

So far so good

Been taking Xendurance for a week and have noticed that I can eke out a couple extra reps on most all sets. I plan to keep taking it to see if gains continue.

Haven’t really vent anything yet

Not sure if I’m too old for this to work (41) but I haven’t felt anything yet. I was hoping to get a little extra on my mountain bike rides or morning runs…. I’m about 2 weeks in, I’ll finish the bag and keep my fingers crossed

We appreciate all feedback but can we ask if you drink a lot of coffee, or juices or eat red meat? Did you chew or swallow the tablets? If you would like more feedback please email info@xendurance.com and we will get back to you with some impute on what may help you! Thank you!
