Mark Sisson, New York Times best-selling author and former endurance athlete, covers the benefits of flexibility on a number of levels. He discusses how to train our metabolism to run more efficiently. As we develop this "metabolic flexibility" – a reliance on fats and ketones for energy – we will likely reduce hunger pangs, burn body fat and increase our energy in the process. He also reminds us of the need to develop flexibility in other aspects of our lives. The ability to "roll with the punches" is needed now more than ever.
