How This Calculator Works

Each exercise has a calorie-per-rep multiplier based on average MET (Metabolic Equivalent of Task) values. This reflects typical energy use for bodyweight or resistance movements.

Formula: Calories Burned = Reps × Multiplier × Weight (kg)

The calculator updates estimates in real time as you change your weight or units. Actual calorie burn may vary based on intensity, rest time, and form. Use this as a guide to help with workout planning and energy tracking.
