Mobility is control, not just range
Being able to reach a position passively is not the same as being able to use it. A hamstring that stretches far when you pull on it, but gives out when you lift from the floor, is flexible without being useful.
The goal is range you can control under load. That distinction changes what you practise: less time hanging in a stretch, more time moving deliberately through a position and holding the ends of it under your own power.
The positions worth keeping
You do not need every joint to move like a gymnast’s. A short list covers most of daily life.
- Getting to and from the floor without using your hands, or with as little help as you can manage.
- Overhead reach with the ribs down, so putting a case in an overhead bin does not become a lower-back movement.
- Hip extension — the ability to stand fully upright after sitting, which desk work erodes quietly.
- Ankle range over the toes, which decides how you descend stairs and absorb landings.
- Rotation through the mid-back, for reversing a car and for everything that involves turning while your feet stay put.
Balance training does reduce falls
This is the part of the guide with the strongest evidence behind it. The systematic review commissioned to inform the WHO’s 2020 activity guidelines pooled 116 randomised trials in 25,160 people aged 65 and over and found that exercise reduced the rate of falls by 23%, rated high-certainty. The reduction was not spread evenly across exercise types. Programmes built on balance and functional training cut the fall rate by 24%; multi-component programmes that combined balance, functional, and resistance work cut it by 28%; Tai Chi by 23%. Walking programmes and resistance training on their own did not produce a clear effect.
Dose mattered too. Programmes delivering three or more hours a week of balance and functional exercise showed the largest reduction in the review, around 42%. The WHO guidance built on this asks adults 65 and over for varied multicomponent activity emphasising functional balance and strength, at moderate or greater intensity, on three or more days a week.
Balance is a skill, and like any skill it responds to specific practice. It is also easy to train in the gaps of a day: stand on one leg while the kettle boils, walk heel to toe along a line, close your eyes for a few seconds while holding a stable surface within reach.
Progress by removing support, narrowing your base, adding head movement, or changing the surface. Keep a wall or a counter close enough to touch.
Where strength fits
Strength work is not a substitute for balance work, but it moves the measures mobility depends on. The Cochrane review of progressive resistance training in older adults found gait speed improved by 0.08 m/s across 24 trials, and getting out of a chair improved substantially across the trials that measured it. Both are mobility outcomes. Neither, on its own, is fall prevention.
The practical reading is that these two blocks of work are complements. Load builds the capacity to hold a position; balance practice builds the ability to find it when the ground is uneven.
Fitting it into a real week
Mobility work fails when it becomes a separate twenty-minute obligation. It succeeds when it is attached to something you already do.
Put a few minutes of range work before your strength session as a warm-up, use end-range positions as filler between sets, and practise balance while you are already standing around. Frequency does more here than duration.
When to get it looked at
Stiffness that improves as you move is usually a training problem. These are clinical questions, and working around them costs more than getting them assessed.
- Pain that is sharp, that wakes you at night, or that follows a specific injury. Get it diagnosed before you programme around it.
- A fall in the past year, or a near-fall you cannot explain. That is a reason to be assessed rather than to train harder unsupervised.
- Dizziness on standing or on turning your head. That points at blood pressure or the vestibular system rather than at your ankles.
- New numbness, pins and needles, or weakness in a limb, or a joint that gives way. See a doctor rather than a mobility routine.
- Stiffness that is worst in the morning, lasts more than an hour, and involves several joints. That pattern belongs with a clinician.
A physiotherapist is the right first stop for most of these. It is worth noting that the fall-prevention programmes behind the numbers above were delivered by health professionals or trained instructors; the review found no difference between the two, but self-directed practice was not what was tested.
What the evidence does not show
- That stretching prevents injury. Fall rate in older adults is the outcome balance and functional training has actually been tested against. Nothing in that evidence base transfers to hamstring strains, back pain, or sports injury.
- That walking is enough on its own. In the falls review, walking programmes did not show a clear effect on fall rates. Walking is worth doing for other reasons; it is not balance training.
- That resistance training alone prevents falls. Same review, same finding. It improves gait speed and chair rise. The fall-rate effect is uncertain.
- That these findings apply below 65. The trials recruited older adults, most of them at some existing risk. Balance is trainable at any age, but the 23% figure is not a number about a 35-year-old.
- That a specific mobility routine outperforms another. The trials tested programmes, not individual drills, and the review could not separate which components did the work.
