Brian Mackenzie is a world-renowned breath coach, professional tinkerer, writer and founder of Power Speed Endurance. I'm grateful to call him a friend and am excited share this deep dive on all things mind, body and breath.

“Breathing is the physiological intercept to our mental state. So, if things are going haywire, I can turn back to my breathing and control the physiological reactions that are happening in my mind. If I can take a step back and do that, I'm actually fixing the entire system.” – Brian Mackenzie
