Our last blog was about which burned the most calories, cardio exercise or strength training. Well if you're looking for the most effective calorie burner try HIIT (High-Intensity Interval Training) which provides similar benefits to cardio but in less time.
HIIT training involves short bursts of very intense exercise alternated with low-intensity recovery periods and normally lasts for approx 10 - 30 minutes.
There has been specific research undertaken to show directly the compared effects of cardio, strength training and HIIT workouts. One particular study compared the calories burned during 30 minutes of HIIT/weight training/ running and biking. The results were that the HIIT workout burned 25–30% more calories than the other forms of exercise.
Overall the largest potential benefit of HIIT is that you can spend less time exercising, since rest periods are included between the intense periods of activity, but still burn a similar amount of calories to cardio/strength training.
If you're new to HIIT then it's best to get some professional guidance on how to use it safely and effectively.
