Calorie burn calculators whether here or on other sites, use an algorithm to determine calories expended based on the MET (metabolic equivalent of task) of the activity and your data (weight, time, etc), therefore they are just estimates. Anything outside a laboratory setting, even a heart rate monitor, offer estimates of calories expended. Calorie burn is achieve by an increase in oxygen consumption in relation to large muscle activation which in turn leads to an increase need for oxygen and nutrients to the working muscles.
I hope this helps!

I'm pretty sure on no planet EVER, would a person burn 150 more calories doing Turbo Jam in a 40 minute workout vs. 40 minutes of Insanity. If you have done both of these workouts, you would for sure know what I'm talking about. Just wondering the reason the calorie-burn counts are so skewed in the tracker???? Thanks!
