Can You Stand on One Leg for 10 Seconds? Here's Why It Matters

Take your shoes off, lift one foot 12 inches off the floor, cross your arms, and see how long you last before you wobble, grab something, or put your foot back down. If you can't hold it for 10 seconds, that's not just an annoying party trick you've lost — it's a number worth paying attention to. A study published in the British Journal of Sports Medicine followed 1,702 people aged 51 to 75 for a median of seven years. Everyone took the same simple test: stand on one leg, unsupported, for 10 seconds. The people who couldn't do it had an 84% higher risk of dying from any cause during the follow-up period than those who passed. Put in plain numbers, 17.5% of the people who failed the test died during the study, compared to just 4.6% of those who passed — even after researchers adjusted for age, weight, and existing health conditions. That's a striking gap for a test that takes less time than it takes to read this paragraph. ## Why Balance Says More About You Than You'd Think Balance isn't one single thing your body does — it's the coordination of your inner ear, your eyesight, the nerves in your feet and ankles, and the strength in your hips, core, and legs, all reporting to your brain in real time. When any one of those systems starts to decline, your balance is often the first place it shows up, long before you'd notice it anywhere else. That's part of why researchers like this test as a screening tool. It doesn't diagnose a specific disease. It's more like a smoke detector — a quick signal that something in the underlying system needs attention, whether that's muscle mass, nerve function, or cardiovascular health. This fits a pattern I've written about before. Grip strength turns out to be a similarly simple, similarly powerful signal, as I covered in Your Handshake Might Predict Your Lifespan Better Than Your Cholesterol. And walking pace tells a related story, which I broke down in Your Walking Speed Might Predict How Long You'll Live. None of these tests cause anything on their own — they're mirrors, not verdicts. But together they paint a picture doctors are increasingly paying attention to: how your body performs simple physical tasks predicts a lot more than we used to assume. ## How to Actually Do the Test Safely Don't do this for the first time alone in the middle of your kitchen with nothing nearby. Here's a safer setup:

• Stand next to a counter, sturdy chair, or wall you can grab instantly if needed.
• Take your shoes off, or wear flat shoes with good grip.
• Lift one foot about 12 inches off the ground, arms crossed or by your sides.
• Look straight ahead at a fixed point, not down at your feet.
• Time yourself (or have someone else time you) until your raised foot touches down or you reach for support.
• Repeat on the other leg — the two sides often aren't equal, and that gap is useful information too.

If you're under 10 seconds on either leg, that's not a diagnosis and it's not something to panic about. It's information. Mention it at your next checkup, and treat it as a reason to start working on balance specifically, not just general fitness. ## The Good News: This One Is Trainable Unlike some of the numbers doctors track, balance responds fast to practice. You don't need a gym membership or special equipment — you need consistency. A few ways to build it into a day you're already living:

• Stand on one leg while brushing your teeth or waiting for the coffee maker — two minutes a day, split between both legs.
• Try tai chi or a water aerobics class. Both are specifically built around controlled shifts in balance, and the water removes the risk of a hard fall while you practice.
• Work on hip and ankle strength, not just legs in general — these are the muscles that make micro-adjustments every time you sway.
• If you've had joint pain limiting movement, pair balance work with joint-friendly activity like what I laid out in Gentle Ways to Stay Active and Protect Your Joints in Your Golden Years.

Balance training isn't glamorous. Nobody posts their one-leg-stand progress on social media. But it's one of the few areas of aging where a few minutes a day at home produces a measurable, retestable result — you can literally time yourself monthly and watch the number move. ## The Real Value Isn't the Number, It's the Feedback Loop The reason this test is worth doing isn't that failing it means something is inevitably wrong. It's that it gives you a concrete, repeatable number tied to something that actually matters — your risk of a fall, and by extension, your independence. Grip strength and walking speed are useful too, but you can't easily train them in your kitchen while the coffee brews. Balance, you can. **Do this today:** time yourself standing on one leg, right now, near something sturdy to grab. Write the number down. Then pick one habit from the list above and do it for two minutes daily for the next month — and retest yourself to see if the number moved.
