Dr. Martin Gibala is a muscle physiologist, professor, and kinesiology department chair at McMaster University in Hamilton, Ontario, Canada. He is best known for pioneering research on the health benefits of high-intensity interval training (HIIT) and his profound understanding of HIIT's physiological mechanisms. He is a co-author of the book "The One-Minute Workout."
