Questions people ask
What is a MET value?
A measure of how hard an activity is compared with sitting still. Calories = MET × weight in kg × hours.
How accurate is this?
It is an estimate. Fitness, technique, terrain and body composition change the real figure.
Do fitness trackers give the same result?
Often not. Trackers use heart rate and other data, and they have their own errors.
