Exercise for pain relief: Why less is more and rivals medication

When movement hurts, exercise can sound like another thing to endure.

A walk becomes something you put off. A fitness class seems out of the question. And advice to “stay active” can feel frustrating when nobody explains how you’re supposed to do that comfortably.

But research offers an encouraging possibility: exercise can help ease pain, and getting relief may take less intensity than you expect.

A sweeping review found benefits across many painful conditions, with larger average improvements in lower-intensity programs. For anyone who associates exercise with pushing harder, that is a welcome reason to reconsider what a useful workout can look like.

Quick Answer

Exercise can reduce pain across a range of conditions. A large review found that lower-intensity programs produced greater average relief than moderate-to-vigorous programs. These comparisons do not establish the best routine for every person, but they support beginning with manageable movement tailored to your condition and abilities.

How much pain relief can exercise provide?

Researchers at Adelaide University analyzed 157 systematic reviews covering 2,736 randomized controlled trials and more than 221,000 participants.

In an analysis using a ten-point pain scale, exercise reduced pain by approximately 1.1 points compared with control conditions. According to the researchers, that reduction was around 60% larger than the average relief reported for common pain medications in separate chronic pain trials.

The review, considered the most comprehensive synthesis of exercise for pain relief to date, included conditions such as low back pain, osteoarthritis, fibromyalgia, rheumatoid arthritis, neck pain and migraine and covered several approaches including aerobic exercise, resistance training, yoga, Pilates and tai chi.

That makes exercise a pain-management tool worth taking seriously.

Why a gentler beginning makes sense

Lower-intensity programs showed greater average pain relief than harder ones. Programs lasting fewer than 12 weeks also performed better on average.

Lead researcher Dr Ben Singh said despite compelling evidence that exercise can deliver meaningful benefits, it remains underused.

“When we exercise, our body releases chemicals including endorphins and serotonin that can help reduce how strongly we feel pain and increase our pain tolerance,” he stated in the press release from Adelaide University.

“Additionally, it helps calm inflammation and change the way our brain responds to pain, while also improving mood.

“These effects help explain why exercise can be such a powerful tool for pain management. Yet despite the evidence, it isn’t used as routinely as it could be and is rarely prescribed with the same precision as medication.

“Instead, people experiencing pain may be told to ‘stay active’, rather than being given a specific, evidence-based exercise program that considers what type of exercise to do, how hard to work and for how long.”

The practical question becomes: What movement can you begin with and repeat?

Choose movement that fits the problem

Start with an activity you can adapt to your symptoms, surroundings and current ability.

If walking feels manageable, keep the first outing short. A level route close to home lets you turn back easily. You do not need to commit to a long distance to establish a starting point. EHO has covered how an individualized walking program helped prevent recurring low back pain.

If weight-bearing activity bothers your joints, consider water exercise or stationary cycling. These are among the low-impact options the CDC recommends for people with arthritis. Gentle tai chi may also appeal if you prefer slower, controlled movement.

If you are unsure which movements suit your condition, ask for specific guidance. A physical therapist can help you identify an appropriate activity, starting duration and way to progress. Bring concrete questions: Should I shorten the session? Change the movement? Use support? How should I respond to a flare-up?

That gives you something more useful than an instruction to exercise more.

Build a routine you can adjust

For arthritis, CDC guidance recommends starting slowly and paying attention to how your body responds. Small amounts of activity count, and you can increase gradually as your ability improves.

One practical approach is to keep a brief record after each session: what you did, how long you did it and how you felt later. Include something meaningful to you, such as whether getting out of a chair or walking to the mailbox felt easier.

This can help you describe your response to a clinician and avoid increasing activity simply because a calendar says it is time.

Some initial soreness can occur when you begin a new activity. But sharp or persistent pain, limping, unusual swelling or pain that worsens at night deserves medical advice. For people with arthritis, the CDC also advises contacting a clinician when pain lasts more than two hours after exercise.

The next time you discuss pain treatment, ask for an exercise plan with the same specificity you would expect from a prescription: what to do, how much to begin with and when to adjust it.

A gentler beginning gives you a way to start — and a routine you can build on.
