Steps

Step count is the most accessible activity metric: nearly every phone and wearable counts it, and it captures the incidental daily movement that structured workouts miss — a big chunk of non-exercise activity thermogenesis and total daily energy expenditure.

What it's good for:

• A trend and a floor. Watching weekly average steps prevents the common trap of "I trained hard, so I sat all day," which can erase a calorie deficit (see kpis-fat-loss).
• A low-friction, motivating target. The familiar 10,000 steps/day figure is a marketing-era round number, not a clinical threshold; benefits accrue well below it, with meaningful health gains seen around ~7,000–8,000 steps/day in observational research, and more steps generally better up to a point.

Limits:

• It's a count, not an intensity — 10,000 gentle steps ≠ a hard cardio session. Pair with active-minutes or HR for intensity.
• Accuracy varies: wrist devices miscount when pushing a cart/stroller, lifting, or cycling, and can over- or under-count; treat absolute totals as approximate.
• Step targets are individual; a deconditioned or older person's meaningful target differs from an athlete's.

For most general-health and fat-loss users, steps are best used as a daily-movement floor that keeps NEAT up, tracked as a weekly average alongside structured training.

• Steps capture incidental movement / NEAT that workouts miss.
• "10,000/day" is a round marketing number, not a clinical cutoff.
• Health benefits seen around ~7,000–8,000/day; more generally better to a point.
• A count, not an intensity — pair with active minutes or HR.
• Wrist counts err during pushing/lifting/cycling; totals are approximate.

• neat — steps are the main trackable slice of NEAT.
• active-minutes — adds the intensity dimension steps lack.
• calories-burned — steps feed device energy estimates.
• kpis-fat-loss — a movement floor protects the deficit.
• neat — habit/behavior side of staying active.
