Interval training after a resistance training workout is a sure way to attack fat stores in the body. Since glucose stores are completely depleted after resistance training, fat is available to be burned. You can perform interval training on a treadmill, exercise bike, swimming, cycling outdoors, boxing, dancing, skipping, walking up-hill or simply by running outside.

It involves repetitions of high speed or high intensity work followed by periods of rest or low activity. An example would be performing 15- to 30-second sprints with 45 to 60 seconds rest. The key to interval training is achieving an elevated heart rate of 75-85% of your maximum heart rate.
