Can You Get Up Off the Floor? Two Free Tests That Predict How Long You'll Live

There's a quiet revolution happening in longevity medicine right now, and it mostly involves very expensive things. Elaborate blood panels. Full-body scans. Membership programs with price tags that make your eyes water. Wearables that assign you a "biological age" and invite you to feel anxious about it.

Here's the thing: some of the most predictive measures of long-term health cost almost nothing. Two of them take less than five minutes combined. And naturopathic doctors have been paying attention to exactly this kind of functional health marker for a long time.

Let's talk about the sitting-rising test and handgrip strength — two deceptively simple assessments with a surprisingly powerful story behind them.

The Sitting-Rising Test: Can You Get Up Without Help?

The premise sounds almost too simple. Start standing. Lower yourself to the floor without using furniture or walls for support. Then get back up.

That's it. That's the test.

Each phase — sitting down and rising up — is scored out of five, for a total possible score of ten. Points are deducted for every time you use a hand, knee, forearm, or the side of your leg for support, and for noticeable wobbling along the way.

What the research found was striking. In a study of over 2,000 adults followed for more than six years, each 1-point increase in score was associated with a 21% improvement in survival. People in the lowest-scoring group were more than five times as likely to die during the follow-up period compared to those in the highest group. A larger follow-up study confirmed the findings — and found that the lowest scorers had six times the rate of cardiovascular death compared to the highest scorers.

Why does getting off the floor predict survival? Because it isn't really about the floor. The test draws on muscular strength, flexibility, balance, and coordination all at once — a snapshot of how your body actually functions, not just one isolated variable. And that functional capacity turns out to matter enormously over time.

Handgrip Strength: The Vital Sign You've Never Had Checked

The other test requires a small handheld device called a dynamometer. You squeeze it as hard as you can for six seconds, a few times per hand. That's it.

Handgrip strength has been studied in populations totalling millions of people across dozens of countries, and the pattern is remarkably consistent: the stronger your grip, the lower your risk of dying from virtually any cause. One landmark study of nearly 140,000 people across 17 countries found that every five-kilogram drop in grip strength was associated with a 16% increase in all-cause mortality and a 17% increase in cardiovascular mortality. Grip strength proved a stronger predictor of death than blood pressure.

Grip strength declines gradually starting in your 40s, which is exactly why it matters to pay attention before the decline becomes significant.

What Actually Helps

The good news is that muscle strength is one of the most responsive targets in the body. It improves with training at any age.

• Resistance training is the most effective intervention — even moderate programs produce meaningful, measurable gains in grip strength and overall function

• Frequency matters more than intensity for most people starting out; consistency beats heroic single sessions

• Protein intake supports muscle maintenance and works synergistically with exercise

• Moderate-to-vigorous movement throughout the week — not just formal workouts — shows a clear dose-response relationship with strength improvement

You don't need a longevity clinic to start. You need a reason to get off the couch and, occasionally, all the way down to the floor.

These two tests won't tell you everything. But they'll tell you something real, something actionable, and something your body already knows. Functional strength is one of the most durable investments you can make in your future self — and it turns out the returns are measurable in years.
