A stretching routine: full body, for flexibility, and how much is enough

This is a routine for being more flexible: reaching your toes, sitting cross-legged on the floor without your knees up by your ears, turning to look behind you without your whole body coming along. It works the whole body, it needs only a floor, a wall and a doorway, and it's built on the dose the research supports.

It isn't the two other routines people often mean. Getting ready to lift is a warm-up, which moves more than it holds. And if your goal is narrower, enough range for your squat, hinge and overhead press, the mobility routine for lifters is aimed at exactly those joints. If a stretch causes pain rather than a pull, or a joint has been hurt before, check with a doctor or a physical therapist before you start.

What a stretching routine does, and doesn't

The one job the evidence agrees on is range of motion. A 2024 meta-analysis of 77 studies found that stretching programs of at least two weeks increased range of motion with a moderate effect compared with not stretching. Static holds and PNF stretching (a hold combined with a brief muscle contraction) did better than ballistic or dynamic stretching.¹ A 2025 consensus statement from an international panel of stretching researchers recommends stretching for that purpose, both for a single session and over the long term, while noting that alternatives exist.²

The same panel was just as clear about what they don't recommend it for. Not as a primary way to gain strength or muscle, not to speed up recovery after exercise, not to change posture, and not, in general, to prevent injuries.² That last one surprises people, so it's worth saying plainly: a stretching routine is for flexibility. Any other reason to do it is outside what this evidence covers.

How long to hold a stretch, and how often

Three sources, and they don't line up perfectly:

• The guideline floor. The American College of Sports Medicine's position stand recommends a series of flexibility exercises for each of the major muscle-tendon groups, a total of 60 seconds per exercise, on two or more days a week.³ Two 30-second holds count as 60 seconds.
• More days, more minutes. A 2018 review of 23 studies found that the time spent stretching per week mattered more than the time in any one session, that gains came once weekly stretching reached at least five minutes, and that more days a week was linked with more range. Its suggestion: static stretching on at least five days a week, for at least five minutes a week.⁴
• Or maybe not. The 2024 meta-analysis, with more than three times as many studies, found that neither the amount, the intensity nor the frequency of stretching played a significant role in how much range people gained.¹

So the honest reading is a floor you can trust and a ceiling nobody has pinned down. Start at the guideline: 60 seconds a stretch, two or three days a week. If you want more range sooner, add days before you add minutes per session, since that's what the 2018 review found mattered, and nothing in the larger analysis says it costs you. The intensity finding is the easy part: a gentle-to-moderate pull is enough, so there's nothing to gain by forcing it.

The routine: full body, about fifteen minutes

Hold each stretch for two rounds of 30 seconds a side, breathing slowly, at the point where you feel a clear pull but no pain. Go into each one gradually and come out the same way; no bouncing.

Done in full, that's about fifteen minutes. On a short day, keep the three areas you feel tightest in and do just those: six minutes, and still inside the guideline for those muscles.³

For beginners: the first week, one round of 30 seconds, then add the second. How far you reach on day one is only the starting point.

For men: in the 2024 meta-analysis, both sexes gained range, though women gained more than men (an effect of 1.55 against 0.88).¹ If you're the stiff one in the room, the routine works the same way. It may just take longer to see.

When to stretch

• At a separate time from lifting. An evening in front of the television, a rest day, or right after a session. The few minutes after a workout are the cool-down page's subject, and stretching there is fine.
• Not as the warm-up for lifting. Long static holds right before heavy sets are the part of this routine that doesn't belong there; the warm-up guide has the numbers and the dynamic alternative.
• Every day, if you like it. Daily is more than the guideline asks for and in line with the 2018 review's five days a week.⁴ It's the same fifteen minutes; doing it more often is a choice, not a requirement.

Stretching routine or mobility routine?

If you lift, there's one more option worth knowing about: in a 2023 meta-analysis of 55 studies, resistance training increased range of motion, and in the studies that compared them, by about as much as stretching.⁵ A full-range lifting program already does part of this routine's job. Foam rolling is the other alternative people ask about: in a 2024 meta-analysis, rolling programs added range about as well as stretching overall, though stretching did better in programs of four weeks or less.⁶

Common questions

How long should you hold a stretch?

About 30 seconds, twice, for 60 seconds in total per stretch: that matches the guideline.³ The consensus panel's recommendation for long-term range runs higher, two or three sets a day of 30 to 120 seconds per muscle, to build up as much weekly time as possible.²

Does stretching prevent injuries?

Not as a general rule, according to the 2025 consensus panel, which didn't recommend it for injury prevention.² If you're working back from an injury, the plan for that comes from a doctor or a physical therapist.

Will stretching fix my posture?

The same panel didn't recommend stretching to promote changes in posture.² If posture comes with pain, see a doctor or a physical therapist.

Is it better in the morning or at night?

None of the reviews on this page compared times of day. Pick the slot you'll keep, since the weeks of repetition are where the range comes from.

If you want it built into a plan

Fifteen minutes of stretching is easy to plan and easy to drop the first busy week. If you're starting out and want flexibility, strength and cardio in one plan that fits your week, that's what I build in coaching: the workouts sit in the Trainerize app, and every week we get on a call, look at what happened, and I set up the next week. Coaching for beginners explains how it works, and you can apply here. Or start smaller: do the three stretches for your tightest areas tonight, and again two more nights this week.
