Everyday movement and steps: Evidence-Based Supplement Guide

Movement outside workouts counts. The WHO 2020 guidelines recommend reducing time spent sitting at every age, and they say that some physical activity is better than none (PMID 33239350). The evidence was not enough to set a threshold for sitting time (PMID 33239350). Short, hard efforts on stairs can build fitness. In a study of sedentary young women, three 20-second all-out stair climbs, three days a week for six weeks, raised peak oxygen uptake by 12 percent (PMID 28009784). A version with three 60-second bouts up and down one flight of stairs raised it by 7 percent (PMID 28009784). Step counts from wearables are more dependable than their calorie numbers. A systematic review of 158 publications found that several brands counted steps accurately in laboratory settings, while no brand measured energy expenditure accurately (PMID 32897239).

1. **Break up long periods of sitting.** The WHO guidelines recommend less sitting at every age (PMID 33239350). 2. **Count any movement.** Some physical activity is better than none (PMID 33239350). 3. **Use stairs for short, hard efforts.** Brief intense stair climbing raised fitness in previously inactive young women (PMID 28009784). 4. **Take calorie estimates as rough.** No brand measured energy expenditure accurately in the review (PMID 32897239). 5. **Compare your step counts on the same device.** Accuracy varied by manufacturer and device type (PMID 32897239).

The stair climbing programmes ran three days a week for six weeks (PMID 28009784). The WHO recommendations are ongoing rather than a course with an end (PMID 33239350).

- **The stair climbing studies were small**, with 31 sedentary young women across two studies (PMID 28009784). - **The device accuracy findings come mostly from laboratory settings**, and devices are often redesigned, so newer models may differ (PMID 32897239). - **The WHO did not set a sitting time threshold**, because the evidence was not enough to quantify one (PMID 33239350). - **This guide has not been reviewed by a clinician.** `reviewStatus` above says so.

- **If you have a long-term health condition or take regular medicines, check with a clinician before adding all-out efforts.** - **Use a handrail when climbing stairs fast**, and stop if you feel unwell.
