What Is EPOC or Excess Post-Exercise Oxygen Consumption? Definition of EPOC EPOC, or Excess Post-Exercise Oxygen Consumption is a measure of increased oxygen consumption after exercise or strenuous activity.  EPOC is also accompanied by a post-exercise increase in energy or fuel consumption  (also characterized as an increase in metabolism.)  EPOC is also known as “oxygen debt” or “oxygen deficit.”  In bodybuilding and fitness training circles it may also be called “exercise afterburn.” Understanding Excess Post-Exercise Oxygen Consumption (EPOC) EPOC occurs after both aerobic (cardiovascular) exercise and anaerobic exercise like weight training.  Following cardiovascular exercise or weight training, the body continues to require oxygen at a level that exceeds oxygen requirements when the exercise began
