Torch 350 Calories in 20 Minutes

Shredding Tactics

You can continue to reap fat-burning effects from your cardio workouts long after they’re over by opting for submaximal intervals, where you work at 80 percent of your all-out maximum effort for one minute, interspersed with one minute of 40 percent effort. Swedish researchers report in the journal Medicine & Science in Sports & Exercise that this type of program burns more fat during the three hours following the session than if you were to train for an hour at a moderate intensity.


To take advantage of this, use the following workout on your choice of cardio equipment (treadmill, elliptical, stationary bike, etc.) to burn major calories during — nearly 350 in 20 minutes — and plenty of fat afterward.
