“Rather than blow off your workout because you don’t have the time or motivation for a 45- or 60-minute session, know there is good scientific evidence validating the efficacy of short workouts,” says Martin Gibala, a professor of kinesiology at McMaster University who studies interval training.

How is it possible that exercising for a fraction of the time can deliver the same results as a longer workout? In short, new research has shown that the same things…
