About This Calories Burned Calculator
Calories burned during exercise depend mainly on body weight, activity intensity, and duration. MET values are a standard way to estimate exercise energy expenditure.
This calories burned calculator estimates calories for common activities such as running, cycling, walking, strength training, swimming, and rowing.
Exercise calorie estimates are useful for planning, but they are not exact. Wearables, machines, and formulas can all overestimate or underestimate real expenditure.
