Hi Reddit! I'm Martin Gibala, PhD, professor and chair of the kinesiology department at McMaster University in Hamilton, Ontario. I conduct research on the physiological and health benefits of interval training and how this time-efficient exercise method compares to traditional endurance training. In my decades of study in this field, I've conducted extensive research on the science of ultralow-volume exercise and time-efficient workouts. Inspired by my own struggle to fit regular exercise into a busy schedule, I set out to find the most effective protocols that take up the smallest amount of time, while still offering the benefits of a traditional session at the gym. It became clear that short, intense bursts of exercise are the most potent form of workout available. One of my recent studies, published in PLOS One, found that sedentary people derived the benefits of 50 minutes of traditional continuous exercise with a 10-minute interval workout that involved just one minute of hard exercise. Study participants who trained three times per week for twelve weeks experience the same improvements in key markers of health and fitness, despite a five-fold lower exercise volume and time commitment in the interval group. My new book, The One-Minute Workout, distills complex science into practical tips and strategies that people can incorporate in their everyday lives. It includes twelve interval workouts, all based on scientific studies, that can be applied to a wide range of individuals and starting fitness levels. From elderly and deconditioned people who are just beginning an exercise regimen to athletes and weekend warriors, there is an interval training protocol that can boost health and performance in a time-efficient manner. Ask me anything about the science of exercise and in particular how to incorporate time-efficient training strategies into your day. Signing out for now! Thank you so much for having me and for all your great questions.
