Are you frustrated by lack of progress despite working hard with high intensity and strength training? You just can't get past that point where your legs start giving out on you.

Did you know that your breathing muscles are in competition with your legs for oxygen? So the more you breathe, the less power is available to keep you moving.

After taking this course, athletes feel like they're 'firing on all cylinders'; able to go further for longer. Your capacity to get oxygen around the body is boosted and you'll feel mentally ready for whatever your A race has to throw at you.

Once your breathing is effective (see Breathe Easy course), you can harness the power of breathing, music and visualisation to excel in your sport

Who is this course for?

This course is designed for those who have either completed Breathe Easy or attended an Oxygen Advantage workshop or masterclass.

Successful athlete looks confident

Hi, I’m Rebecca - breathing specialist for sport

I was a competive freediver for several years, setting 5 UK records swimming on one breath. Much of my training was in carbon dioxide tolerance and in becoming as efficient as possible in thought, breath and movement.

So I know breathing, and not breathing!

In this advanced course, I share with you the Oxygen Advantage exercises plus training I've learnt over the years that have helped me be a better athlete (also in running and triathlon) and human being.

A key focus on this course is pre-race preparation. I had an hour-long routine which I honed to perfection so that I started my events in the best possible mental state. Here I help you craft a routine of your own.
