Massive calorie burning phenomenon EPOC stands for Excess Post-exercise Oxygen Consumption. It’s when one works out at a high enough intensity the body goes into a metabolic deficit. The process of making up for this metabolic deficit equals calorie burning. And depending on the level of intensity, it can take your body up to 48 hours after your workout to make up for this deficit. One of the best ways to trigger the EPOC effect is to do cardio interval workouts, not long steady-state cardio. Interval cardio means doing short bursts of super intense cardio followed by a rest period of lower intensity cardio, repeated a number of times. For example, walk for 15 seconds then sprint for 15 seconds, and repeat several times. Or running up a set of stairs and walking down. Metabolic resistance training is another great way to trigger EPOC. It’s going to feel like cardio, but we are using our muscles to get the job done. For example, the classic Mountain Climber Exercise. It can yield a much more appealing physique!
