Elliptical calorie burn averages 5–12 kcal per minute — roughly 150–360 kcal in 30 minutes — based on your weight, resistance, cadence, and effort.

On an elliptical, a 30-minute workout burns about 180–450 calories; weight, speed, resistance, and incline swing the total.

Workout calorie burn varies by size and intensity; most people expend about 150–450 calories in 30 minutes from light to vigorous exercise.

On a treadmill, a 70-kg person burns about 80–280 kcal in 20 minutes, depending on speed, incline, and whether rails are used.
