Workout Calorie Calculator

How to Use This Workout Calorie Calculator

Exercise calorie burn depends on your body weight, exercise intensity, and duration. Heavier individuals burn more calories for the same workout. Heart rate is the most accurate real-time indicator of intensity. Most fitness trackers overestimate calorie burn by 20–30%, so treat estimates as approximations. Enter your measurements above for an instant result based on established health guidelines.
