Why stretching matters

The short answer

The honest truth about stretching
Stretching has been oversold and undersold at the same time. It has been oversold as an injury preventer — the evidence that stretching before sport prevents injury is genuinely weak, and I would rather tell you that than repeat something comfortable. And it has been badly undersold as what it actually is: one of the simplest, cheapest ways to keep your body moving well for the rest of your life.
Here is what I see, week after week. People do not usually come to me because they suddenly injured themselves. They come because they have slowly, quietly stopped moving through their full range — sitting more, reaching less, turning less — and one day their back seizes up reaching into the boot of the car. The stiffness came first. The pain came later.
What does stretching actually do?
Stretching maintains and gradually improves the range of movement available at a joint. Do it regularly and two things happen: the tissues themselves adapt over time, and — just as importantly — your nervous system becomes more comfortable letting you move into that range.
That second part is the one people miss. A good deal of stiffness is protective. Your body limits movement it does not trust. Stretch regularly and gently and you teach your body that the range is safe again.
Flexibility or mobility — what’s the difference?
Flexibility is how far a joint can be moved passively — how far someone could move it for you.
Mobility is how far you can move it yourself, with control.
Mobility is the one that matters in real life. Being able to touch your toes is a party trick. Being able to get out of a chair, look over your shoulder when reversing, and get your shoes on without a fight — that is mobility, and that is what we are actually training for.
When should you stretch?
Before exercise: move, don’t hold
Use dynamic stretching — controlled movement through range. Leg swings, arm circles, gentle squats, walking lunges. You are warming tissue and waking up the nervous system. Holding long static stretches immediately before something explosive can briefly reduce power output, so keep it moving.
After exercise, or as its own session: hold
This is where static stretching earns its keep. Ease into a stretch until you feel a mild pull — not pain — and hold it for 30 seconds. Then repeat two or three times. Most people hold for about eight seconds, decide nothing is happening, and give up. Thirty seconds is the number.
A simple ten-minute daily routine
This covers the areas that seize up most in modern life. Do it most days. Ease in, breathe, and never push into sharp pain.

Hip flexors, kneeling. Kneel on one knee, tuck your tailbone under, and gently shift forward. 30 seconds each side. If you sit a lot, this one alone is worth the ten minutes.
Hamstrings, seated. Sit on the edge of a chair, straighten one leg out with the heel on the floor, and hinge forward from the hips with a flat back. 30 seconds each side.
Chest and shoulders, doorway. Forearm on a doorframe, elbow at shoulder height, and turn away gently. 30 seconds each side. Counteracts a lifetime of leaning forward.
Upper back rotation. Sit or kneel, hands behind your head, and rotate slowly to each side. Ten slow turns each way. This is mobility rather than a hold — move into it.
Calves, against a wall. Hands on the wall, one foot back, heel down, knee straight. 30 seconds each side.
Cat-cow, on all fours. Slowly arch and round your back, ten times. It is the best thing I know for a back that has been sitting all day.
That is it. Six movements, ten minutes. The value is entirely in doing it most days — not in doing it perfectly.
Where stretching is not the answer
I want to be straight with you here, because it will save you time. If something has been
painful for weeks and stretching is not shifting it, stretching is probably not the answer. Persistent pain usually needs assessing — there may be a strength deficit, a movement pattern that is loading the wrong tissue, or something else going on entirely. Stretching a tissue that is irritated can make it more irritated. Stretching is brilliant maintenance. It is rarely a cure.
Frequently asked questions
How long should I hold a stretch?
Around 30 seconds, repeated two or three times. Anything under about 15 seconds is unlikely to achieve much.
Should I stretch before exercise?
Move before exercise rather than holding stretches — dynamic movements that take your joints through their range. Save the long holds for afterwards or for a separate session.
Should stretching hurt?
No. You should feel a mild pull, never sharp or nervy pain. Pain is a signal to back off, not to push harder.
How often should I stretch?
Most days beats occasionally. Ten minutes daily will outperform an hour at the weekend every time.
Can stretching fix my back pain?
It often helps, and it rarely does harm. But if the pain has been there for weeks, get it assessed — you may be stretching something that actually needs strengthening.
