How to Use the Cardio Calorie Efficiency Calculator
Calories burned during cardio is calculated as MET × body weight (kg) × duration (hours). MET (Metabolic Equivalent of Task) represents exercise intensity relative to rest. HIIT (MET 12) and jump rope (MET 11) are over 3× more efficient than walking (MET 3.5).
When time is limited, HIIT or running offers the best calorie-per-minute return. For joint-friendly options, swimming or cycling is ideal. Heavier individuals burn more calories for the same exercise. Long-term consistency matters more than short-term intensity spikes.
Frequently Asked Questions
HIIT and jump rope lead in calorie efficiency (MET 10–12). Running (MET 8–11) is next, with cycling and swimming as lower-impact alternatives.
MET (Metabolic Equivalent) measures intensity relative to rest. Calories = MET × weight × hours. A MET of 1 equals your resting metabolic rate.
HIIT is most efficient per minute, but the best cardio is what you can sustain consistently. If you have joint issues, swimming or cycling is a great choice.
