So your suggesting aerobis exercise on an empty stomach. Without rubbishing your coments, i found this statement on a website and its not the only one which makes this claim.
Intervals help you burn extra calories because they work your muscles harder than steady, moderately paced aerobic exercise. And because they work both aerobic and anaerobic systems, intervals do a better job of helping you retain muscle while losing fat. The more carbohydrates burned by your muscles to fuel the higher intensity exercise, the more fat burned after the exercise to repair, replenish and rebuild these muscles. |
