Patrick’s book, The Oxygen Advantage® is a godsend for anyone wishing to improve their performance in a way that doesn’t involve hours of strenuous workouts, drills, and endless miles of running. I’ve been doing nose breathing for the past ten years and it has totally revolutionized my running and seriously dropped my effort levels… at every speed! It’s simple to incorporate into your training and your daily life. and the results are astounding. I now recommend it in all of my running classes and training programs. Every runner or athlete should have this book. If you’re not breathing right, you’re working too hard.
