Skeptical at first but now a believer

I was skeptical that this worked, and certainly to what extent. Last year I was able to run 10 miles plus multiple times a week. I have had a really did great time getting even to 6. After about two weeks of Xendurance I am able to hit 6-7 no problem. I don’t feel tired or gassed. My heart rates still goes up. My knees certainly still hurt too lol.
I’m hoping to keep the success going forward and be back to long runs.

Thank you for sharing your experience with Extreme Endurance. We are so glad to hear that you are now a believer in our product. It's always great to hear success stories from our customers!

It works-seriously!

I’d been taking the recommended amount for a few months and noticing small increases in my fitness and endurance while biking and running. But the real testament was my ability to keep up with the front pack in a one-day, 150 mile, 10,000 feet of climbing ride around Mt. Rainier. Amazing!

Thank you for choosing Extreme Endurance! We are thrilled to hear that you have noticed improvements in your fitness and endurance while using our product. Congratulations on your impressive ride around Mt. Rainier! Keep up the great work and we hope Extreme Endurance continues to support you on your fitness journey.

More Than What I Expected

I started taking Extreme Endurance about three weeks before my marathon in Bandera, Texas. I felt strong from beginning to end. What really won me over is the marathon had 3,000 feet of elevation. I have never run a marathon with more than 500 feet of climbing before. In addition, I placed first in my age category. I will have to say Extreme Endurance played a huge role.

I am sold on the product and will continue to use in the future.

Thank you for sharing your positive experience with Extreme Endurance! We are thrilled to hear that our product exceeded your expectations and helped you perform at your best during your marathon. Congratulations on placing first in your age category - that is truly impressive! We are honored to have played a role in your success and we look forward to continuing to support your fitness journey.

Your race at your pace.

I started taking Extreme Endurance about a month ago after finishing a half marathon in nearly 3 hours. Initially, I was pretty skeptical but figured I had nothing to lose. I’ve been running for over a decade as a way to stay fit after retiring from the Navy. After knee surgery last year, I just wanted to get back into the rhythm of running. Following that almost 3-hour half marathon on 9/14/2014, I set a goal to complete a sub-2-hour half marathon before my 60th birthday in December.

The very next week, I began my journey with Extreme Endurance. I also decided to run without music, focusing instead on my breathing. On 10/6/2024, I ran a half marathon in 2 hours and 20 minutes, and on 10/19/2024, I improved to 2 hours and 15 minutes. I’ve noticed I’m not out of breath during runs, and my recovery after intense runs is faster. I even set my personal best times for both the 5K and 10K this past weekend. I’m well on my way to breaking the sub-2-hour barrier before I turn 60 in December. I’m living proof that Extreme Endurance works.

Thank you for taking the time to share your success with Extreme Endurance! We are thrilled to hear that our product has helped you achieve your running goals and improve your overall performance. Your dedication and hard work are truly inspiring, and we are honored to be a part of your fitness journey. Keep up the great work, and we wish you all the best in breaking that sub-2-hour barrier before your 60th birthday! Remember, your race, your pace. We wish you continued success in your future races. 💪 Keep pushing to the extreme!
