Did you know that you can accomplish the same thing in half the time by upping the intensity of your workouts? For years, you’ve heard about things like “fat burning zone” and moderate intensity for 45-60 minutes, right?
As it turns out, when you do high intensity workouts for 20 minutes or less, you put your body under such a high load/stress that it burns as much or more energy to recover than it would going at a moderate pace for an hour or more! Check out the results of a study done on this subject by McMaster University here…
Try this: Speed sit ups. Get a partner and hold their feet. Take turns sprinting in sit up intervals. Go as possible in each interval, and make the switch between partners FAST – 15 sec, 30, 45, 60, 45, 30, 15.
