What you'll walk away with

The CO₂ science most coaches were never taught

Understand oxygen delivery and CO₂ tolerance — the mechanisms that directly govern performance under physical and mental stress. This is the missing layer in most coaching education.

Protocols that hold at high intensity

Standard breathing cues collapse when training gets hard. Learn structured approaches that build real, measurable CO₂ tolerance so performance breathing becomes automatic — not something athletes have to think about.

A measurable baseline for every client

Our breathing assessments give you an objective before-and-after metric. Trackable progress changes what your client conversations look like — and what you can charge for results.

A clear pathway to specialist certification

See exactly how OA certification fits your coaching model, what 1.9 NASM/AFAA CEUs means for your recertification, and how instructors are using it to open doors to specialist positioning, higher rates, and B2B work with clubs and academies.

FAQ

Who is this Masterclass for?

Built for coaches who take athlete outcomes seriously

Body — fitness coaches & PTs

You programme everything meticulously. Breathing is the one variable without a rigorous framework — until this.

Mind — sports & S&C coaches

Your athletes train at intensity. You've noticed breathing is a limiter but haven't had tools to address it systematically.

Sport — endurance coaches

You work in marginal gains. Breathing efficiency is the most under-optimised variable in most endurance programmes.

What experience do I need?

No prior breathwork training is required. The Masterclass is designed for professionals who understand the basics of working with clients but are new to teaching breathing techniques. We’ll build your knowledge from the ground up.

Will I be able to use these techniques right away?

Yes. The Masterclass focuses on practical, ready-to-use protocols. You’ll learn clear assessment methods and specific breathing techniques you can begin incorporating into your client work immediately after the training.
