Focus: How short, vigorous exercise compares with longer moderate exercise for fitness and metabolic health
Dr. Martin Gibala is an exercise physiologist and professor at McMaster University who has spent much of his career studying high-intensity interval training. Emphasizes time-efficient exercise: how short, vigorous efforts compare with longer moderate sessions for fitness and metabolic health. Draws primarily from his own lab's training studies, many of them small proof-of-concept trials, and is open about that limit; he is also the author of a book on brief interval workouts.
