Finally, the solution to the #1 reason we don't exercise: time. Everyone has one minute.

A decade ago, Martin Gibala was a young researcher in the field of exercise physiology-with little time to exercise. That critical point in his career launched a passion for high-intensity interval training (HIIT), allowing him to stay in shape with just a few minutes of hard effort. It also prompted Gibala to conduct experiments that helped launch the exploding science of ultralow-volume exercise. Now that he's the worldwide guru of the science of time-efficient workouts, Gibala's first book answers the ultimate question: How low can you go?

Gibala's fascinating quest for the answer makes exercise experts of us all. His work demonstrates that very short, intense bursts of exercise may be the most potent form of workout available. Gibala busts myths (“it's only for really fit people”), explains astonishing science (“intensity trumps duration”), lays out time-saving life hacks (“exercise snackin
