How to use this calculator

  1. Enter your current workout or body metrics.
  2. Adjust the intensity, frequency, or nutrition target to match your goal.
  3. Click Calculate and review the score, status, and recommendation.

What the result means

The result estimates active calories from exercise. Higher weekly calories support fat loss, but results should be interpreted with food intake, recovery, and consistency.

Calories burned = MET × body weight in kg × workout duration in hours.

MET values are estimates. Strength training, running, cycling, and swimming can produce different calorie burns at the same duration.

Example calculation

A 70 kg person running at 8 MET for 30 minutes burns 8 × 70 × 0.5 = 280 kcal per session.

Tips for better results

  • Increase duration gradually before raising intensity.
  • Use the same MET value each week for consistent tracking.
  • Combine workout calories with a moderate calorie deficit.
