Once again, research has dictated change in our industry. Gone are the days of climbing on a treadmill and walking at a pace that is comfortable for an extended period of time, with the expectation of intense weight loss or incredible conditioning. Research shows us that the lack of intensity limits the results you get. In order to reach the fat loss goals that most people are trying to achieve, they need high intensity interval training or tabata workouts. These workouts traditionally consist of a five-minute warm-up; a fifteen-minute active work/active recovery cycle, and a five-minute cool down. The active work/recovery portion is designed to spike your heart rate for a short burst (the "active work" portion), let it come down to a moderate rate (the "active recovery" portion), and then spike it again. Though these workouts are short, they typically double the output of calories burned and extend caloric burn for the next 24 to 48 hours. You will benefit from an elevated metabolic rate because your body will continue to burn fat efficiently.
