Though HIIT short for high intensity interval training has been around for a long time, it is only recently that researchers have identified the underlying physiological changes that take place with this type of training. Not only does HIIT appear to be superior for improving cardio-respiratory fitness, it is also an effective strategy for burning calories, promoting weight loss, and improving insulin sensitivity. And the best part is that most HIIT workouts take a fraction of the time required by more traditional steady-state, moderate-intensity workouts. In fact, in "The One Minute Workout," researcher Martin Gibala claims that exercisers can meet and even exceed the benefits of a 50-minute moderate intensity workout in as little as 10 minutes.
The workouts below are adapted from "The One Minute Workout" and provided here for my client's convenience. They range in time from approximately 10 minutes to 30 minutes, but they all share a common theme: short bursts of intense activity. And while the effectiveness of these specific protocols have been studied and verified through research, it's possible that other variations yield similar benefits.
