Calories Burned Calculator
Estimate calories burned during specific exercises based on body weight and duration
What This Calculator Does
This calculator estimates how many calories you burn during specific exercises based on MET (Metabolic Equivalent of Task) values, your body weight, and exercise duration. MET values represent the energy cost of physical activities as multiples of your resting metabolic rate. Higher MET values indicate more intense activities that burn more calories per minute.
The Formula
Example Calculations
Example: 30 minutes of push-ups
A 170 lb (77.1 kg) person doing push-ups for 30 minutes. Calories = 8.0 x 77.1 x 3.5 / 200 x 30 = 324 calories burned.
Example: 20 minutes of burpees
A 150 lb (68 kg) person doing burpees for 20 minutes. Calories = 10.0 x 68 x 3.5 / 200 x 20 = 238 calories burned.

How to Use Your Results
Calorie burn estimates help you understand the energy cost of your workouts, but they are approximations. Actual burn varies based on intensity, fitness level, and individual metabolism. Use these numbers for general planning rather than precise tracking. Pair with Fitnit AI-powered exercise tracking for more accurate workout data based on your actual reps and form.
