Is stretching or strengthening better for neck and back pain?

Is stretching or strengthening better for neck and back pain? For neck pain from desk work, strengthening has the stronger evidence: programmes that build strength in the neck, shoulders and upper back, or combine strengthening with stretching, have done better than stretching on its own. For the lower back the picture is more mixed, and the type of exercise seems to matter less than doing some at all. For most people who sit all day, the honest answer is both, and strength is the part a stretching routine leaves out.

Neck pain: strengthening has the edge

The broadest summary is the Cochrane review of exercise for neck pain, which pooled 27 trials with 2,485 people analysed. For neck pain that had lasted a long time, it found:

• moderate-quality evidence that strength training for the neck, the shoulder blade area and the arms improved pain;
• a beneficial effect, from small to large, for programmes that combined strengthening and stretching for the neck, shoulders and shoulder blades;
• low-quality evidence that stretching on its own may not change pain or function in the short term.

The authors found no high-quality evidence for any type of exercise, so some uncertainty remains. But their conclusion was direct: strengthening and endurance exercises for the neck, shoulders and upper back may help, while stretching alone may not be expected to (Gross et al., 2015).

A year-long trial in office workers

One of the clearest comparisons ran for a full year. 180 women office workers aged 25 to 53 with long-term neck pain were split into three groups. One did high-intensity strength training for the neck with an elastic band, one did lighter endurance training, and both also exercised the shoulders and arms. The third group was the comparison. Everyone, including that group, was advised to do aerobic exercise and stretching three times a week.

After twelve months, pain and disability had fallen more in both training groups than in the comparison group. Neck strength in the strength group rose by as much as 110%. And it was not only strength: only the strength group improved its range of movement in bending the neck forward, backward and to the side, compared with the group that had been advised to stretch. The authors concluded that stretching and aerobic exercise alone were a much less effective form of training than strength training (Ylinen et al., 2003).

Targeted works better than general

A smaller trial asked whether any exercise would do. 48 women in repetitive jobs such as computer work, all with chronic pain in the upper trapezius, were assigned to ten weeks of strength training for that muscle, to cycling with relaxed shoulders, or to no exercise. Worst pain fell by about 79% with the targeted strength training. Cycling brought only a small, short-lived drop (Andersen et al., 2008).

Reviews limited to office workers point the same way, with caveats. One found eight trials, mostly of strengthening, and a clinically meaningful drop in pain compared with no exercise; it found too few stretching trials to judge (Louw et al., 2017). A later review of eight trials rated the evidence for strengthening as low certainty, because every included trial had a high risk of bias (Jones et al., 2024).

Where stretching fits for the neck

Stretching is not useless. In a trial of 96 office workers, four weeks of neck and shoulder stretching reduced pain by 1.4 points more on a 10-point scale than an ergonomics brochure alone (Tunwattanapong et al., 2016). So stretching beats doing nothing extra. What it has not done is match strengthening, and the programmes with the best support use both. We go through the stretching trials in more detail in Do stretches help neck pain?

Lower back pain: a more mixed picture

For long-term non-specific low back pain, the basic message is that exercise helps. A Cochrane review of 249 trials found moderate-certainty evidence that exercise reduced pain by about 15 points on a 0 to 100 scale compared with no treatment, usual care or placebo (Hayden et al., 2021).

Which kind of exercise is less clear, and stretching is where the analyses disagree.

• A network analysis of 217 trials with 20,969 people found that Pilates, McKenzie therapy and functional restoration were more effective than other types of exercise. Flexibility exercises showed a clinically important effect on day-to-day function, though not on pain. The authors’ advice was to encourage people to do the exercise they enjoy, so that they keep doing it (Hayden et al., 2021, network analysis).
• Another network analysis of 89 studies ranked Pilates highest for pain, and resistance training and stabilisation or motor control exercise highest for function. Stretching did not differ from no treatment for either pain or function. The authors rated the evidence as low quality (Owen et al., 2020).
• In a trial of 228 adults with chronic low back pain, twelve weekly yoga classes improved function and symptoms more than a self-care book, but yoga was no better than conventional stretching classes at any point (Sherman et al., 2011).

So for the lower back, stretching may help some people, and a stretching class can hold its own against yoga. But Pilates, which builds strength and control, was among the most effective types for pain in both network analyses, and resistance training ranked well for function in one. If those interest you, see Does Pilates help back pain? and Is yoga good for back pain?

How much strengthening does it take?

Less than you might fear.

• In a trial of 198 adults working at least 30 hours a week with frequent neck and shoulder pain, training with an elastic band for 2 minutes a day, five days a week, for ten weeks reduced pain by 1.4 points on a 10-point scale compared with a group given general health information. Twelve minutes a day reduced it by 1.9 (Andersen et al., 2011). There is more on that trial in Is two minutes of exercise enough?
• In a trial of 447 office workers, one hour a week of neck and shoulder strength training reduced neck pain whether it was done as one long session, three medium ones or nine short ones (Andersen et al., 2012).
• The NHS recommends strengthening activities that work all the major muscle groups, including the back, shoulders and arms, on at least two days a week. Its examples range from lifting weights to yoga, Pilates and carrying heavy shopping (NHS).

What this means if you sit at a desk all day

You do not have to choose. A workable split for most desk workers looks like this:

• Stretching and mobility for the working day. Short, regular sessions break up long sits and keep the neck, shoulders and upper back, the thoracic spine, moving. Pages such as neck stretches and upper back stretches explain individual exercises, and How often should you stretch? covers how often.
• Strengthening at least twice a week. For the neck and shoulders, that is where the trial evidence is strongest. For the lower back, exercises that ask your muscles to hold and control your trunk, such as the bird dog and the glute bridge, are one place to start.

If your pain has lasted months or keeps returning, a physiotherapist can examine you and pick the right exercises and load for what they find. If cost is a worry, see how much physiotherapy costs. There is more on each area in neck pain from desk work and lower back pain from sitting.

Where Bavelu fits

It is fair to say this plainly, since the evidence above favours strength. Bavelu is built around stretching and mobility. Its sessions include a few bodyweight exercises that ask muscles to work, such as the bird dog and the glute bridge, but there are no weights or bands, so it is not the progressive strength training used in the neck trials. Think of it as the regular movement between your strength work, not a replacement for it.

When to see a doctor

Neither stretching nor strengthening is the right first step for every symptom. The NHS advises seeing a GP if neck pain or stiffness has not gone after a few weeks, painkillers have not helped, you are worried, or you have other symptoms such as pins and needles or a cold arm (NHS). For the back, see a GP if the pain has not improved after a few weeks or is worse at night. Call 999 or go to A&E if back pain comes with numbness or weakness in both legs, loss of feeling around your genitals or anus, changes in bladder or bowel control, or chest pain (NHS).

So, is stretching or strengthening better?

• Neck: strengthening, or strengthening combined with stretching, has better evidence than stretching alone.
• Lower back: most exercise helps; strength and control approaches rank well, and the evidence on stretching is split.
• Desk workers: keep the stretching for the working day, and add some strength work at least twice a week.
