Calories burned = (MET x 3.5 x weight(kg) / 200) x duration(minutes)
Inputs
Nutrition
Calculate your daily calorie needs based on the Mifflin-St Jeor equation. Get personalized BMR, TDEE, and target calories for weight loss, maintenance, or gain.
Formula
BMR (Male) = 10×weight + 6.25×height − 5×age + 5. BMR (Female) = 10×weight + 6.25×height − 5×age − 161. TDEE = BMR × Activity Factor.
