>>76340243>I can run for 25 minutes and burn that manyYour app is lying to you. Fitness watches, apps, exercise equipment, ect all grossly overestimate how many calories you burn. The only reliable way to gauge caloric burn is via CO2 analysis. 400 calories is what you can expect to burn after running for an hour, not 25 minutes.
Take whatever your app tells you you burned and cut it in half, that'll usually be pretty close to what you actually burned.
