Grip Strength and Longevity: What the Research Actually Measures

What PURE measured

The 2015 PURE study analyzed 139,691 adults across 17 countries. Researchers measured squeeze force with a dynamometer and followed health outcomes for a median of four years.

Lower handgrip strength was associated with higher all-cause and cardiovascular mortality. These were population associations, not predictions of an individual’s remaining lifespan.

What it did not show

Participants were not assigned a dead-hang training program. The authors explicitly called for further research into whether improving strength reduces mortality and cardiovascular disease. The study also reported no significant association with injury from falls or fractures.

It therefore cannot substantiate claims that this app, a longer hang, or a particular daily dose prevents falls or extends life.

Hang time is a different measurement

A dynamometer records squeeze force. A timer records how long you hold a position. Body weight, bar dimensions, foot support, technique, and fatigue all affect a hang. The results are not interchangeable.

Hang Habit tracks time and practice history. It does not measure clinical grip strength, calculate disease risk, or provide a longevity score.

Use your history for a practical question

“Am I returning to a manageable practice?” is a question your session history can help answer. “How much longer will I live?” is not.

Compare sessions with similar setups. Keep rest in your plan and avoid using a streak or record to override how you feel. If you want to understand a clinical grip measurement, discuss the test and your wider health context with a qualified professional.
