What Systematic recommends
Where to start
- A pull-up bar or other secure bar to hang from and the floor or a stable box/platform high enough to let your feet control how much body weight is placed through your hands, arms, and shoulders.
- Step onto the floor position or stable box/platform beneath the bar. Place your hands just outside shoulder width. Use full palm contact on the bar. Wrap your thumbs around the bar. Lower yourself down under control while keeping your feet and legs involved enough to regulate how much body weight your upper body is supporting.
- Hold for 30 seconds. Use approximately 50% assistance from your feet and legs. Rest for 30 seconds. Repeat for 3 total rounds. Maintain an even grip through both palms. Allow the elbows to straighten. Allow the shoulder blades to elevate and soften. Keep the amount of loading controlled through the feet throughout the hold. Breathe fully and smoothly for the duration of the hold.
- Stop and reassess if you feel pain or discomfort, if you are unable to control the amount of body weight through your feet and legs, or if you can no longer maintain a comfortable grip and controlled hanging position.
Condensed from the published Development Pathway (The Dead Hang: Floor-Supported Decompression Hang). This is a starting point, not a training program or medical advice.
What the test asks you to do
You hang from a bar in a standardized passive position and hold your own body weight through your grip for as long as you can. Systematic records time until grip support is lost, a foot contacts the floor or support, the participant steps down or ends the attempt, or an assessment safety-stop criterion occurs. It is Test 08, the last test in the assessment.
The time captures more than your hands. Your wrists, elbows, shoulder girdle and the muscles that hold your posture all have to coordinate to keep you supported overhead, and grip failure and that upper-body stabilization are linked rather than separate.
How it differs from a grip-strength test
A grip dynamometer asks how hard your hand can squeeze at one moment. The Dead Hang asks how long you can keep holding your own weight. The two are related capacities, not interchangeable ones: the connection is real but directional, and one is not a stand-in measurement for the other.
What the research shows and what it does not
The foundational study here is Leong and colleagues' PURE study, which measured handgrip strength with a dynamometer and linked it to health outcomes. It did not use dead hangs and gives no dead hang norms. Systematic deliberately extends that grip-strength research by timing how long you can support your own body weight from a standardized bar.
The direct dead-hang study cited here, Exel and colleagues (2026), followed what happens as a hang approaches failure. As fatigue sets in, the work shifts from the fingers and forearms toward the joints and muscles closer to the trunk, and the muscles start working more closely together.
That study involved 11 recreational advanced-to-elite male climbers, so it explains the mechanism but is not a norm for the general population. Neither Leong nor Exel supplies Systematic's standards.
How Systematic scores it
Your hang time is scored against Systematic standards for your age and sex. The result is a physical baseline. It is not a diagnosis and it does not predict disease or lifespan.

The evidence
Each cited source is labeled according to how it supports the particular claim on this page. Direct test evidence, underlying-capacity findings and population reference values are distinguished from Systematic-defined protocols and standards. Historical development notes are retained internally rather than presented as public evidence. A study of an underlying capacity is never presented as validation of the Systematic test itself.

Underlying-capacity evidence
Leong et al. (2015). Prognostic value of grip strength: findings from the Prospective Urban Rural Epidemiology (PURE) study. The Lancet.
What it found. PURE measured handgrip strength with a dynamometer, not with dead hangs, and showed that grip strength is relevant to health outcomes.
What it does not show. It does not provide dead-hang norms and does not supply thresholds used for Systematic standards.
-
Direct test evidence
Exel et al. (2026). Upper‐Body Neuromechanical Coordination Strategies During Fatiguing Sustained Dead Hangs in Climbers. European Journal of Sport Science.
What it found. In a small sample of climbers, coordination shifted from the fingers and forearms toward the joints and muscles closer to the trunk as a dead hang approached failure.
What it does not show. It studied 11 recreational advanced-to-elite male climbers hanging from a wooden edge rather than a bar, so it is not a general-population norm and does not supply Systematic standards.
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.
