The Wall Sit: the standards by age and sex
Systematic-defined standard (never a published clinical cut-off) Scoring version healthspan_v2_2026_08. Red, yellow and green are Systematic standards, not published clinical cut-offs.
| Cohort | Red · Priority capacity | Yellow · Functional target | Green · Exceptional capacity |
|---|---|---|---|
| Female, 18–34 | 0–49 seconds | 50–159 seconds | 160+ seconds |
| Female, 35–55 | 0–39 seconds | 40–134 seconds | 135+ seconds |
| Female, 56+ | 0–29 seconds | 30–99 seconds | 100+ seconds |
| Male, 18–34 | 0–44 seconds | 45–149 seconds | 150+ seconds |
| Male, 35–55 | 0–34 seconds | 35–119 seconds | 120+ seconds |
| Male, 56+ | 0–24 seconds | 25–89 seconds | 90+ seconds |

What Systematic recommends
Where to start
- Sit on the far side of the chair or stable surface. Place the lead foot directly underneath the lead knee and maintain full tripod-foot contact through the working foot.
- Align the pelvis and thorax so the pelvic bowl and thoracic bowl are stacked, lean or bow forward until you begin to load the working foot and elevate your hips approximately 2 inches off the chair.
- Hold the hover for approximately 5 seconds or 2 breath cycles, lower back down under control until you make contact with the chair and reset on the chair for approximately 5 seconds before repeating.
Condensed from the published Development Pathway (The Wall Sit: Seated Hover and Staggered Rise). This is a starting point, not a training program or medical advice.
How to read the table
Find the row for your sex and age. Your time falls into one of three bands: red is a priority capacity, yellow is the functional target and green is exceptional capacity. Each cohort has its own bands, and they are the same standards that score every Systematic assessment.
The hold is an exact 90-degree position. The hold is timed until the first protocol stop criterion or voluntary termination, and the actual elapsed time is recorded without an arbitrary cap.
The number you see during the test
While you test you see one neutral number: the functional anchor for your own cohort. It sits inside the yellow band, which like red and green is a Systematic standard. It is a reference point, not a band boundary, and it comes from the same cohort standards as the table.
Why there are six cohorts
Systematic scores the Wall Sit with six age and sex cohorts rather than one figure for everybody, so you are compared with standards set for people of your own age and sex.
The Systematic Healthspan Assessment is a physical baseline. It is not a diagnosis, and it does not estimate a biological age, a disease risk or a lifespan.
