What is EPOC?

EPOC stands for Excess Postexercise Oxygen Consumption, and it refers to the boost in metabolism, or calories and fat burning, that comes after a workout.

When you train, you burn calories to fuel your muscles, but when you´re done, your body keeps burning more calories and fat than normal.

This is due to the process involved in recovery: after exercise, your body must repair damaged muscle fibers, restock muscle glycogen levels, remove lactic acid from the muscles, etc. All these processes require calories, and a lot of those calories may come from bodyfat.

High Intensity Interval Training boosts EPOC much more than cardio done at one steady intensity level.
