These Two Bodyweight Tests Are Major Longevity Markers For Women

Reported by MindBodyGreen.

Longevity research loves a dramatic reveal — the biomarker you never saw coming, the metric your doctor forgot to order. But a study published in JAMA Network Open makes a case for something almost embarrassingly low-tech: squeezing as hard as you can and standing up from a chair five times. According to MindBodyGreen, these two bodyweight tests may be among the most telling predictors of how long women live.

Researchers tracked roughly 5,500 women between ages 63 and 99 over approximately 8.4 years, measuring dominant-hand grip strength and the time it took participants to complete five unassisted chair stands. The results were striking. Women in the strongest grip category had a 33% lower risk of death than those with the weakest grip; women who completed the chair stand test fastest showed a 37% lower risk compared to the slowest group. Crucially, these associations held even after controlling for physical activity, sedentary behavior, walking speed, and inflammation — meaning strength offered a protective signal independent of whether someone was hitting their cardio goals.

What Each Test Is Actually Measuring

These aren't interchangeable metrics. Grip strength reflects overall neuromuscular function and skeletal muscle output — the kind of whole-body efficiency that prior research has tied to cardiovascular health and disability risk. The chair stand test draws on something broader: lower-body power, balance, coordination, and the ability of multiple systems to fire together under fatigue. The correlation between the two scores was notably small, which tells you each one captures something distinct about functional resilience and independence. Women in the top quartile for grip strength squeezed over 24 kilograms; for the chair stand, finishing five reps in 11 seconds or less placed women in the strongest category. No dynamometer at home? Flag difficulty with everyday tasks — opening jars, hauling groceries — as an early signal, and ask your doctor or physical therapist to formally assess you. For the chair test, sit in a firm chair with feet flat and arms crossed over your chest, stand fully and return to seated five times without using your hands, and time the whole sequence.

The point isn't to spiral over your numbers. Muscle strength is modifiable — it responds to resistance training, bodyweight work, and even the functional load of daily life. Carrying bags, climbing stairs, getting off the floor: it all counts. The research is essentially handing you a baseline and a reason to act on it, not a verdict.

Consider this your reminder that the most powerful longevity tool you have isn't a supplement stack or an expensive panel — it's building and maintaining the muscle you already have.
