How are calories burned during exercise calculated?

Calories burned are calculated using MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities. The formula is: calories = MET x bodyweight in kg x duration in hours. MET values represent the energy cost of an activity relative to rest.

Does weightlifting burn more calories than cardio?

Per minute, vigorous cardio typically burns more calories than weightlifting. However, resistance training builds muscle mass which increases your BMR, meaning you burn more calories at rest. A combination of both is optimal for total calorie expenditure.

How accurate are calories burned calculators?

MET-based calculators are accurate within 15-20% for most people, according to research from the American College of Sports Medicine. Individual variation in metabolism, fitness level, and exercise intensity can affect actual calorie burn.
