If you’re curious about your life expectancy, you could invest in expensive full-body scans or complex blood tests that estimate your “biological age.” But research suggests there’s a much simpler approach: a handful of quick, low-tech fitness tests that offer surprisingly accurate clues about how long—and how well—you might live.
“These assessments take only a few minutes and require almost no equipment,” says Dr. Jonathan Myers, clinical professor at Stanford University and health researcher. “What they measure—strength, balance, endurance—are key functional abilities strongly tied to longevity.”
Here are five evidence-backed movement tests you can try at home, why they matter, and how to improve your performance.
1. The One-Leg Balance Test
The challenge is straightforward: stand on one leg, with the other lifted off the floor, and see how long you can hold your balance.
In a long-term study of nearly 2,000 older adults, those unable to balance on one leg for at least 10 seconds had a significantly higher risk of death during the study period. Balance time tends to decline steeply with age—especially after 50—unless you deliberately practice it.
Why it matters
Balancing on one leg forces the brain, muscles, and sensory systems to work in unison. “If you can hold for 30 seconds, you’re doing well,” says Dr. Kenton Kaufman of the Mayo Clinic. “And if that’s easy, try it with your eyes closed.” Strong balance reduces fall risk, which is one of the leading causes of disability and mortality in older adults.
How to improve
Practice daily—while brushing your teeth, folding laundry, or waiting for your coffee to brew. To build balance-supporting muscles, stand on one leg while holding a chair for stability, then slowly extend your other leg to the side or back.
2. The Dead Hang
Grab a pull-up bar with both hands and simply hang for as long as you can. This is a modified grip strength test—one of the most reliable predictors of health and longevity.
Why it matters
Grip strength reflects overall muscular strength, which is linked to stronger bones, fewer falls, and longer life. “It’s not just about opening jars or carrying groceries,” says Dr. Deborah Kado, co-director of Stanford’s Longevity Center. “Grip strength is a proxy for how resilient your body is.”
Benchmarks
- Ages 20–40: 75–90 seconds is excellent (especially for men)
- Ages 40–60: 60–75 seconds
- Age 60+: 45 seconds
How to improve
Since grip strength mirrors total-body strength, a full resistance program is best. Start with dumbbell rows and deadlifts, and add direct grip work like squeezing a stress ball or using resistance bands.
3. The Sit-and-Rise Test
From a cross-legged seated position on the floor, try standing up without using your hands, arms, or knees for support. You begin with a score of 10 and lose one point each time you use an extra limb for help; wobbling costs half a point.
Why it matters
Getting up from the floor demands both strength and balance—two critical factors for independence as you age. In large studies, higher scores on this test strongly correlated with longer life expectancy.
How to improve
Strengthen the lower body with squats, lunges, and glute bridges. Progress to single-leg moves like curtsy lunges to further challenge balance and control.
4. The Chair Stand Test
This is a simpler alternative to the sit-and-rise: sit in a chair, cross your arms over your chest, and stand up repeatedly without using your hands. Two versions are common:
- 5-Times Sit-to-Stand Test: How quickly can you stand and sit five times?
- 30-Second Sit-to-Stand Test: How many can you complete in half a minute?
Why it matters
Performance reflects lower-body strength, endurance, and coordination—all of which help prevent falls. Faster times and higher counts are also linked with better heart and lung function.
Benchmarks
- Under 40: complete 5 reps in under 10 seconds
- Add 1 second per decade after age 40
- For the 30-second test: ~33–35 reps is strong under age 35; 12+ reps is good at 60+
How to improve
Double down on lower-body work: squats, step-ups, and lunges. Complement with side-lying moves like clamshells and fire hydrants to strengthen stabilizers.
5. Walking Speed
It may sound too simple, but your natural walking pace is one of the strongest independent predictors of survival.
Measure yours by timing how long it takes to walk six meters and dividing distance by seconds. Speeds slower than 1 meter per second are associated with shorter lifespans in older adults. Other research shows even 15 minutes of brisk walking per day can lower mortality risk by nearly 20%.
Why it matters
Walking speed integrates cardiovascular health, muscular strength, and nervous system function. Plus, moving quickly helps you safely navigate real-world challenges—like crossing a street before the light changes.
How to improve
Incorporate more walking into your day. Gradually increase pace, add hills, or mix in short jogs to build endurance and efficiency.
The Bottom Line
These tests aren’t crystal balls, nor do they capture every factor that influences longevity—like cognition, social connection, or genetics. And temporary conditions (fatigue, soreness, illness) can skew results.
Still, because they’re simple and widely studied, they provide valuable snapshots of your physical resilience. Stronger balance, grip, endurance, and speed aren’t just numbers on a stopwatch—they’re markers of a body better equipped to live longer, healthier, and more independently.
