When you get your breathing right, you'll notice some incredible results. Probably just listening to this will make you breathe deeper. Brian Mackenzie is a world-renowned strength and conditioning coach. He's trained gold and olympic medalists including, as you'll hear, his wife. He's also a New York Times bestselling author, entrepreneur, and all-round good guy. He created Cross Fit Endurance which is wildly popular and has written genuine bestsellers.
