Ryan McCahey, founder and head coach of Rebirth

The founder

Rebirth is my story first.

I'm Ryan. I was never the one into fitness. For a long time I was on the wrong path, dealing with my mental health, and I hit rock bottom before I started looking for a way out.

Bit by bit I found things that helped me manage my life better: training, breathwork, the right habits and the right people. They changed the whole direction of my life. That was my own rebirth. Now I get to help other people change theirs.

I believe that no matter where you're starting from, with the right habits, the right environment and the right people around you, you can have your own rebirth and change your life. That's what Rebirth is about.

Breathwork with Ryan

Alongside the gym, I run breathwork as its own thing. It isn't part of a Rebirth membership. It's what helped me find my way back, and now I teach it to anyone who wants it.

I'm an Advanced Oxygen Advantage Instructor and a Yoga Lab-trained breathwork and meditation teacher. Sessions are practical and evidence-led, with no wild claims.
