What Is Cadence (SPM)?
What 100 SPM Can—and Cannot—Tell You
Steps per minute describes walking pace. Around 100 SPM is a practical starting estimate of moderate intensity for many adults, not a personal aerobic threshold or a guaranteed health outcome.
Tudor-Locke et al. (2018, PMID 29858160) proposed about 100 SPM as an easy-to-use estimate of absolutely defined moderate intensity (3 METs) in generally healthy adults. It is a population-level, laboratory-derived estimate; personal effort varies with age, fitness, terrain, and health. Total and brisk steps are complementary measures, not substitutes.

Calculate your target steps per minute (SPM) based on your height and speed:
Total Steps and Brisk Steps
These are not competing targets; they summarize movement volume and walking pace from different angles:
| Physiological Metric | Conventional 10,000 Slow Steps | ONK Brisk 3,000 Steps (100+ SPM) |
|---|---|---|
| Average Cadence (SPM) | Lower-pace example | 100+ SPM (practical moderate-intensity marker) |
| Heart Rate & Training Zone | Heart-rate response varies | Not equivalent to Zone 2 |
| Metabolic Equivalent (MET) | Depends on speed and the individual | May indicate roughly moderate intensity |
| Dimension Summarized | Daily movement volume | Walking pace and duration |
| Required Duration | Can accumulate throughout the day | Varies with personal goals |
| Health Outcome | Associated with total movement volume | Considered alongside pace and duration |
Clinical Cadence Gateways (Tudor-Locke Model)
In biomechanical literature, step rates are categorized into four distinct physiological zones:
< 80 SPM: Incidental Strolling
Intermittent indoor shuffling. Does not raise core body temperature or stimulate cardiovascular adaptations.
100–119 SPM: Brisk Walking
The clinical gateway to moderate intensity (3 METs). Drives cardiac output, nitric oxide vasodilation, and GLUT4 glucose uptake.
120–130+ SPM: Vigorous Cardio
This cadence may approach vigorous intensity for some adults. Perceived effort and heart-rate response vary by person.
Questions on Walking Cadence & SPM
Not at all. 100 SPM equates to roughly 4.5–5 km/h (2.8–3.1 mph). It feels like walking with a purposeful, rhythmic stride as if you have a train to catch.
ONK continuously samples accelerometer feeds on iPhone and Apple Watch to filter out sporadic indoor shuffling, counting only sustained rhythmic aerobic steps above your personalized gate.
Yes. Increasing step frequency rather than overstriding shortens the braking lever arm, substantially reducing impact shocks on knee joints and hips.
