Balance Is Power is an enlightening and thought-provoking read. It will make you view the world differently! Jim describes how the world we live in today has severely weakened our natural balance - we live in perfectly aligned living/working spaces, are always looking down at our phone screens, wear poorly designed athletic shoes, etc. - something I never thought about or noticed before. Jim’s insights and methods have made me realize the potentially life-and-death importance of balance, not just for athletes but for all humans. This book is great not only for anyone wanting to improve athletic performance at any level but also just for anyone wanting to feel stronger, healthier and more in control of their body.
