Similar to how a car’s engine remains warm after being turned off, once a workout is over and you’re back in your daily routine, your body’s metabolism can continue to burn more calories then when at complete rest. This physiological effect is called excess post-exercise oxygen consumption, or EPOC.

What is EPOC and why does it happen?

EPOC refers to the elevation in metabolism (rate that calories are burned) after an exercise session ends. The increased metabolism is linked to increased consumption of oxygen, which is required to help the body restore and return to its pre-exercise state.

Is the EPOC effect real?

Unlike most fitness myths, EPOC is in fact a real effect that contributes to caloric expenditure. However, this doesn’t perfectly translate to fat loss… although it can help. The amount of fat you burn ultimate depends on a few factors, like how much fat you have to start with and your metabolism rate.
