got my breath back

I am currently training for my 7th Ironman which is coming up in November. Prior to taking this and post "covid" time I was having issues with catching my breath. Whichever discipline I was training in I was finding myself gasping for air, just looking to maintain a steady breathing pattern which I had never had a problem with before.
Since starting Xendurance I havent had issues with catching my breath, my runs have improved to where they should be, I feel great on the bike, and my breathing during swimming is consistent. I also have been feeling better and recovering faster during my weight training sessions. Def worth the purchase.

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!

Fastest 5k I've run in years!

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.
