Why 10,000 Steps on a Hill Burns Far More Than 10,000 Steps on Flat Ground: Gradient and Calorie Reality

Walking uphill burns substantially more calories per step than flat walking — but most step-to-calorie calculators don't account for this. A 70 kg person walking brisk on flat ground burns ~315 kcal/hour; the same person hiking uphill at 10% grade burns ~525 kcal/hour for the same steps. Here's the physics of vertical work, how MET values capture gradient, why GPS devices estimate terrain calories better than accelerometers alone, and the descending asymmetry (downhill costs fewer calories but isn't free).

How Step Counters Actually Work — and Why Your Phone and Smartwatch Never Quite Agree

A smartphone in your pocket and a fitness tracker on your wrist can disagree by 10-20% on the same walk — and neither is necessarily "wrong." Here's how accelerometer-based step counting actually works, why wrist-worn and hip-worn devices have different error patterns, what validation studies show about accuracy, and why trend-tracking matters more than absolute numbers.

Walking Pace and Longevity: Why How Fast You Walk Predicts Health Better Than Step Count

Brisk walkers have 35% lower all-cause mortality and 54% lower cardiovascular mortality than slow walkers — independently of total walking volume. Here's what "brisk" means in measurable terms, the dose-response curve from pace improvements, and why gait speed predicts health in ways step count doesn't.

The 10,000 Steps Myth: What the Research Actually Says About Daily Walking

The 10,000-step target came from a 1964 Japanese pedometer marketing campaign. Here's what the research actually shows about optimal step count, how steps translate to calories, and why step intensity matters as much as step count.
