At O2 Collective, our mission is simple: to help you breathe better so you can live better.

With more than 20 years of experience in performance, breathwork, and human optimization, we’ve seen firsthand how intentional breathing can be a game-changer—whether in managing stress, enhancing focus, or supporting long-term well-being.

We believe that breathing isn’t just a function; it’s a skill—one that, when refined, can positively shift your mind, body, and life.

Through practical techniques rooted in science and experience, we’re here to guide you in integrating breathwork seamlessly into your daily routine and professional practice.

Wherever you are on your journey, we’re honored to be part of it.

One breath at a time, let’s reshape the way you breathe, move, and thrive.

Here to support,

Meet the CapnoTrainerGO

Your breathing patterns reveal more than you think.

The CapnoTrainerGO is a powerful tool that measures your exhaled CO₂ in real time, giving you immediate insight into how your breathing is affecting your body, mind, and performance. It’s a simple, non-invasive way to track and retrain your breathing—based not on guesswork, but on real data.

Whether you’re a wellness practitioner or just breath-curious, this device can help you or your clients understand and transform dysfunctional breathing habits at the source.
