MET stands for metabolic equivalent and this measure is used to estimate the energy expenditure of a task. One MET is defined as the amount of oxygen consumed whilst at rest, this is 3.5ml/kg/min. So an activity that is a level 3 MET, means it takes 3 times the amount of oxygen as being at rest. We use MET values to estimate calorie expenditure in Simaktiv.
When you enter a workout, use the MET slider scale to understand what MET level your activity should be at. For workouts within the Lessons section, the description suggests MET levels for each workout.
