How long should you be able to dead hang? There is no norm

We searched PubMed on 12 October 2026 for "dead hang", "bar hang", "straight arm hang", "passive hang" and "hang time" (search record). The hits were climbing studies in small groups of trained climbers, a method for scoliosis X-rays, and police fitness tests. None gave population norms. None measured mortality, falls or independence.

A usable norm would need three things: one defined protocol, a sample of ordinary adults tested by age and sex, and ideally an outcome followed over time. None of the hits had even the first two for a straight-arm hang in adults.

That is absence of evidence in one database, not proof that nothing exists anywhere. Military and police standards were not searched in full. If a validated adult norm turns up, this page will change.

The closest tests that do have norms are youth tests with bent arms. The HELENA study published percentiles for the bent-arm hang in 3,428 European adolescents aged 12.5–17.5. That is a different position, a different age group and a different purpose.

One small study shows what a hang measures. In 60 college women, flexed-arm hang time correlated with one-rep maximum per kilogram of body weight (strongest r = 0.72), but not with absolute strength or with endurance. A hang tests how strong you are for your size. Two people with the same grip will hang for different times if one is heavier.

Popular articles on hang time and longevity tend to cite one paper: a narrative review of grip strength by Bohannon (2019) (source check). The coaching page whose bands Longstanding uses lists only grip studies (Dodds 2014, Leong 2015, Bohannon 2019) and says itself that its hang bands are not medically validated percentiles.

The grip evidence is real. Across 42 cohorts, each 5 kg of lower grip went with about 16% higher mortality (Wu 2017). But a grip test is a few seconds of maximal squeeze. A hang also depends on body mass, shoulder tolerance and grip endurance, so the grip findings cannot be carried over to hang time.

And even the grip evidence is observational. In PURE, 139,691 adults across 17 countries, weaker grip went with higher mortality and predicted it more strongly than blood pressure did, but nobody was assigned to get stronger (Leong 2015). If grip itself is not proven to add years, a hang test borrowing its results has even less to stand on.

A percentile needs a measured population: you test many people of a given age and sex and see where each result falls. A coaching band is someone’s judgment of what counts as weak, fair or strong.

Bands can still be useful for setting a training goal. They cannot tell you how you compare with other people your age, and they cannot tell you anything about your health. When a hang figure is presented as "normal for your age", ask what population it was measured in. For the dead hang, the answer so far is none.

Without a norm, the honest use of a hang is as your own trend over time. That only works if the conditions are the same each time, so fix them:

• The same bar, overhand grip, hands shoulder-width, thumbs around the bar.
• No straps and no chalk.
• Start from a full hang, stepping off a box, feet off the ground, arms straight.
• Hold your shoulders the same way every time.
• Stop the clock when either hand leaves the bar or a foot touches down.

Remember the body-weight effect. Because hang time tracks strength relative to body weight, losing or gaining weight will move it even if your grip has not changed. Note your weight with each result.

Expect some noise. Take more than one attempt with a few minutes of rest and keep the best, as the app does with three attempts and three minutes between them. A change of a few seconds from one quarter to the next may be a bad day. A change that holds over two or three quarters is a trend.

The dead hang carries the "estimated" label everywhere it appears in the app. Its band comes from coaching ranges, and the app reduces those ranges by 20% per decade after 45, which is our own assumption and is stated on the test page. The calculator shows the same estimate, with the same label.

The app does not say the dead hang predicts how long you live. It keeps the test because hanging on is a practical ability, the movement behind catching a rail after a slip, and because a quarterly trend in your own hang time is informative even without a norm.

Your line for the hang, the result you need today to still manage the goal you chose for 85, is built on the same estimated band. So the line is an estimate too. The trend in your own results is the part you can trust most.

Stop if your shoulder hurts. This is not medical advice.
