High-intensity interval training (HIIT) workouts are the latest fitness craze and are touted as the fastest way to get lean. But new research from the University of Sydney's Charles Perkins Centre suggests such workouts don’t burn fat, and endurance exercise is the best way to shed pounds.
The study, led by exercise physiologists Shelley Keating and Nathan Johnson, M.D., found regular continuous aerobic exercise yields better fat loss results than HIIT workouts for overweight people.
"A growing number of people are substituting HIIT for regular aerobic workouts in their exercise routine, but high-intensity interval training is not a fast track to quick fat loss if you're overweight," said Keating. "High-intensity burst training does deliver important benefits like increased fitness, but it doesn't have a 'fat furnace' effect if you carry weight around the middle."
For the study, the researchers compared the effects of HIIT and continuous aerobic exercise on body fat levels among overweight adults. The results, published in the Journal of Obesity, suggest HIIT workouts can be useful for people who are time-pressed, but in the long run, you’re better off going with conventional aerobics exercises if you’re trying to lose weight.
