Every claim on this site about accuracy is backed by a named, checkable source, not a vague ‘studies show.’ This section breaks down exactly where treadmill and wearable calorie numbers come from, why they disagree with each other, and what actually moves the number on your specific workout.
- Why Treadmills Overestimate Calories — the UC San Francisco testing behind the “your console is probably wrong” claim, and what it means for your number.
- Treadmill vs. Apple Watch, Fitbit & Garmin — why your console and your wearable almost never agree, and which one to actually trust.
- The Handrail Effect — the real, peer-reviewed number for how much gripping the rails cuts your calorie burn.
- Does Gender Affect Treadmill Calorie Burn? — what actually drives the difference, and it isn’t what most people think.
- Heart Rate vs. MET-Based Calculators — two completely different methods for estimating the same thing, compared honestly.
