High-intensity interval training (HIIT) describes any workout that alternates between intense bursts of activity and fixed periods of less-intense activity or even complete rest. Just 2 weeks of high-intensity intervals improves your aerobic capacity as much as 6 to 8 weeks of endurance training.
“Some studies state that HIIT burns 9x more fat than traditional cardiovascular exercise. HIIT burns a lot of calories during the workout, but where it differs from traditional cardiovascular exercise it that your metabolism stays elevated for more than 24 hours afterwards!”
