"Fatigue and a lack of energy are among the top wellness issues facing Americans. There's no two ways about it: we're exhausted and depleted and desperate for practical, long lasting solutions. Most people don't realize that the main reason we're so exhausted is that we're living in a way that's counter to our biological rhythms-our chronobiology-and our innate physical needs. In Energize! renowned sleep doctor Michael Breus and founding instructor of SoulCycle Stacey Griffith team up to help readers get back on track. Using the core principles of chronobiology and fitness, they offer a simple, personalized program of small, daily movements, sleeping and eating on schedule, and mood hacks that will give readers incredible energy, promote happiness, and fight off fatigue for good. Their program boils down to living the way nature and your DNA programmed you to live. With fascinating science, quizzes so that readers can identify their chronotype (Lion, Wolf, Bear, or Dolphin) and their body type (ecto, endo, or mesomorphic), and easily implemented advice, Energize! will have you feeling happier and healthier in no time"-- Provided by publisher.
