Balance and mobility: moving freely for life

Getting up off the floor, standing on one leg and walking briskly all depend on muscles, joints, eyes, inner ear and brain working together. These simple tests predict lifespan surprisingly well, and they're all trainable.

01
The basics

What balance is made of

Your brain keeps you upright by mixing three streams of information: what your eyes see, what your inner ear senses about head movement, and what sensors in your feet, joints and muscles report about your position. It then fires the right muscles, fast.

All of these fade slowly with age and inactivity, and leg power (strength produced quickly) fades fastest. You often don't notice until you trip and can't catch yourself.

Falls are the leading cause of injury death in adults over 65. But balance responds quickly to practice, often within weeks.

The sit-to-rise test

Sit down on the floor and stand up again without support. Start at 10 and lose a point for each hand, knee or forearm you use.

Stand Sit (5 points) Rise (5 points) −1 for each hand, knee or forearm used · −½ for losing balance

How it works

How your body keeps you upright

1

Eyes

Tell you where the horizon and obstacles are.

2

Inner ear

Fluid-filled canals sense tilt and head movement.

3

Feet & joints

Pressure and stretch sensors report your exact position.

4

Brain → muscles

Combines it all and triggers quick corrections in your ankles, hips and trunk.

03
Measure it

Three tests you can do at home

  • One-leg stand: stand barefoot on one leg, other foot resting behind the standing calf, arms by your sides, eyes forward. Can you hold it for 10 seconds? Have someone nearby or stand next to a wall.
  • Sit-to-rise test: lower yourself to sit cross-legged on the floor, then stand up. Start from 10 points (5 for sitting, 5 for rising) and lose 1 point for each hand, forearm, knee or side of leg you use for support, and half a point for losing balance.
  • Walking speed: time yourself walking 4 metres at your normal pace from a moving start. Divide 4 by the seconds to get metres per second.

What the newest research adds

New large trials show that simple, regular strength and balance classes cut falls by about a third, even in rural villages. But not every gentle exercise works: a yoga trial built on held poses actually led to more falls, so the type of training matters.

The new studies, in order

Every study added to this page since January 2025. Green rings are the strongest evidence: large trials or meta-analyses.

A year of balance and strength exercise led by village doctors cut the share of people who fell from 38.3% to 29.7%, a 33% drop. Falls causing injury fell from 21.6% to 15.2%.

Oliveira et al. (SAGE)

700 adults aged 60+, 12 months

Online Iyengar yoga led to about 33% more falls than seated relaxation, though not more injurious falls. People who were already active or felt their balance was good were most at risk, so held poses are no substitute for proper balance training.

Pettersson et al. (Safe Step)

1,628 adults aged 70+, 12 months

A self-guided app of home balance and strength videos cut the chance of falling at least once from 59.6% to 53%. The total number of falls did not drop significantly, so apps help a little but are not a full answer.

What this changes for you

Pick training that actually challenges balance and strength: standing on one leg, stepping, heel-to-toe walking, sit-to-stands, ideally in a class. Gentle held poses alone may not protect you, and could even add falls if you're already active.

Take action

How to improve it

A few minutes a day is enough. Make it a little harder as it gets easy.

  1. 1

    Daily one-leg stands

    While brushing your teeth: 30 seconds each leg. Then try with eyes closed, or on a cushion.

  2. 2

    Practise the floor

    Get down to the floor and back up a few times a day, using as little support as you can.

  3. 3

    Strengthen legs and hips

    Squats, step-ups, lunges and calf raises twice a week.

  4. 4

    Train power

    Stand up from a chair quickly, climb stairs briskly. Speed of muscle response prevents falls.

  5. 5

    Try tai chi or dance

    Both train balance, coordination and confidence.

  6. 6

    Check the basics

    Eyesight, foot pain, medicines that cause dizziness, and trip hazards at home.

Myth or fact

Common myths, checked

✕ MythFalls are just bad luck.

✓ FactMost falls have causes you can change: weak legs, poor balance, eyesight, medicines and home hazards.

✕ MythBalance can't be trained after a certain age.

✓ FactOlder adults improve balance quickly with practice, often in a few weeks.

✕ MythWalking is enough to keep balance.

✓ FactWalking helps, but balance needs specific challenge, like standing on one leg or changing direction.

Questions

Frequently asked

What's a good one-leg time?

Under 50, most people can hold 30 seconds or more with eyes open. Over 70, 10 seconds is a reasonable goal.

Is the sit-to-rise test safe?

Do it on a soft surface with something sturdy nearby. Skip it if you have bad knee or hip pain or have been told not to kneel.

Why does walking speed matter?

It's a summary of your heart, lungs, muscles, joints and brain all working together.

True

Not being able to stand on one leg for 10 seconds in midlife is linked to higher death risk.

Araujo 2022 (BJSM) found people aged 51–75 who failed the test had about 84% higher risk of death over 7 years.

Card № 02True or myth?

Tai chi reduces falls in older adults.

True

Tai chi reduces falls in older adults.

Several trials and meta-analyses show tai chi cuts falls by roughly 20–40%.

Card № 03True or myth?

Balance gets worse with age and nothing can be done.

Myth

Balance gets worse with age and nothing can be done.

Balance training works at any age. Falls drop by about a quarter in exercise trials (Sherrington, Cochrane 2019).

Card № 04True or myth?

The sit-to-rise test (getting down to the floor and up without using hands) predicts survival.

True

The sit-to-rise test (getting down to the floor and up without using hands) predicts survival.

Brito 2014: each point on the 10-point test was linked to about 21% lower risk of death.

Card № 05True or myth?

Stretching every day prevents injury.

Partly true

Stretching every day prevents injury.

Static stretching before exercise does little to prevent injury. A dynamic warm-up and strength work do more.

Card № 06True or myth?

Strong legs and hips are key to good balance.

True

Strong legs and hips are key to good balance.

Balance depends on the strength to correct a wobble, not only on the inner ear and nerves.

Card № 07True or myth?

Closing your eyes makes no difference to balance.

Myth

Closing your eyes makes no difference to balance.

Vision does a lot of the work. Eyes-closed balance drops much faster with age, which is why it's a useful test.

Card № 08True or myth?

Falls are the leading cause of injury death in adults over 65.

True

Falls are the leading cause of injury death in adults over 65.

In many countries falls top the list, which is why balance training counts as a longevity habit.

Card № 09True or myth?

Flexibility is only for yoga fans.

Partly true

Flexibility is only for yoga fans.

You don't need splits, but enough range in hips, ankles and shoulders keeps everyday movements and balance easy.

Card № 10True or myth?

Practising balance on one leg while brushing your teeth is a real training method.

True

Practising balance on one leg while brushing your teeth is a real training method.

Small daily doses add up; progression (eyes closed, soft surface) keeps it challenging.
