Quick answer: Yes — exercise is safe for most people with osteoarthritis, and current clinical guidelines recommend it as first-line treatment, ahead of surgery and often alongside or instead of medication. The right kind of supervised, progressively loaded exercise reduces pain, improves joint function, and in many cases reduces or removes the desire for joint replacement surgery altogether.
If you’ve been told to rest your joint, take anti-inflammatories, and “see how it goes,” you’ve had the most common advice given to people with osteoarthritis in Australia — and it’s advice that, on its own, tends to make things worse rather than better.
Here’s what the research actually says, why the “rest it” instinct is understandable but misguided, and what an effective, evidence-based exercise program looks like.
What Is Osteoarthritis?
Osteoarthritis (OA) is the most common form of arthritis, affecting an estimated 3.2 million Australians, with prevalence rising sharply from age 45 and highest in people 75 and over. It’s more common in women (10.2%) than men (5.6%), and while ageing is a factor, it isn’t the only one — obesity and previous joint injury are two of the biggest modifiable risk factors for both developing OA and it progressing further.
OA involves the gradual breakdown of cartilage in a joint — most commonly the knee or hip — leading to pain, stiffness, and reduced range of motion. Morning stiffness that eases within 30 minutes, pain that builds with activity and settles with rest, and a general sense that the joint “doesn’t move like it used to” are typical early signs.
It’s a mechanical and biological condition, not simply a symptom of getting older — which matters, because it means it responds to treatment.
Why “Just Rest It” Is the Wrong Advice
The logic feels sound: if a joint hurts, using it must be causing damage, so the safest thing to do is protect it by moving less.
In practice, this belief is one of the most consistently reported barriers to recovery in osteoarthritis research. Studies of people living with OA repeatedly describe a resigned, fatalistic attitude toward staying active, along with a fear that pain during movement means harm is being done. The result is a slow retreat from activity — fewer walks, stairs avoided, hobbies quietly dropped — which leads to deconditioning, weight gain, and often more pain, not less.
The uncomfortable truth is that rest doesn’t strengthen the muscles supporting the joint, doesn’t improve the joint’s capacity to tolerate load, and doesn’t address the underlying mechanics driving the pain. It simply avoids the problem in the short term while it continues in the background.
What the Research Actually Says About Exercise and Arthritis
Exercise is recommended as a first-line treatment for knee and hip osteoarthritis in current clinical guidelines — not a last resort after medication and injections have failed, and not something to attempt only once surgery has been ruled out.
The strongest real-world evidence comes from structured education-and-exercise programs, most notably the GLA:D® (Good Life with Osteoarthritis Denmark) model, which has now been delivered across hundreds of sites in Australia. Published Australian outcomes data from this program shows:
- An average pain reduction of around 36%
- A joint-related quality of life improvement of around 31%
- Roughly 3 in 4 people who initially wanted a joint replacement no longer wanted one 12 months later
That last point is worth sitting with. This isn’t a claim that exercise replaces surgery for everyone — for some people, joint replacement will still be the right call, and exercise therapy also improves recovery outcomes when surgery does happen. But it does mean that, for the majority of people, trying a properly built exercise program first changes the picture significantly, often more than people expect.
Some discomfort during appropriately loaded exercise is normal and expected — it isn’t a sign of damage. It’s usually a sign that the exercise hasn’t yet been matched to where the joint is starting from, which is precisely the gap a supervised program is designed to close.
Common Questions People Ask Before Starting
Won’t exercise wear my joint out faster? No. Appropriately loaded exercise is recommended as first-line treatment in current clinical guidelines. The aim is the right load for your joint’s current capacity, not the absence of load altogether.
I’ve already been told to lose weight — isn’t that the real fix? Weight management helps, since it’s an important modifiable risk factor for both OA onset and progression. But exercise improves pain and function independently of weight change, and it supports weight loss rather than substituting for it.
Wouldn’t a joint replacement just solve this properly? For some people, eventually, yes. But guidelines recommend exercise therapy be tried first, and real-world data shows many people no longer want surgery after completing a structured program. If surgery is still needed later, being fitter and stronger going in also improves recovery.
I’ve tried exercise before and it just made things worse. This is common, and it’s usually a sign the exercise wasn’t matched to the joint — either too much too soon, or not supervised closely enough to adjust when something flared. A program built and progressed by an Exercise Physiologist is specifically designed to avoid this.
Do I need a GP referral to start? No — you can book an initial assessment directly. If you’re eligible for a Medicare Chronic Disease Management (EPC) plan or DVA funding, we’ll help you get the right referral sorted afterwards.
What an Effective Exercise Program Actually Involves
Not all “exercise for arthritis” advice is created equal. A generic sheet of stretches or a walking recommendation isn’t the same as a program built around your joint. An effective program typically includes:
- A proper initial assessment — your joint history, current function, pain patterns, and personal goals (getting back to golf, gardening, or simply the stairs without hesitation).
- Clear education — understanding what’s actually happening in the joint and why exercise helps, rather than a generic hand-out.
- Progressive, supervised loading — starting at a level your joint can currently tolerate and building from there, adjusted as you improve or if something flares.
- Regular review — tracking pain, function, and progress over time, not a one-off program handed over and left unchanged.
This is the model used in evidence-based programs like GLA:D, and it’s the model an Accredited Exercise Physiologist is specifically trained to deliver.
Why Rebound Health’s Osteoarthritis Programme
Rebound Health’s Osteoarthritis Programme is built and delivered by Accredited Exercise Physiologists, using the same first-line, education-plus-exercise approach backed by the research above — not a generic gym program repurposed for joint pain.
What that means in practice:
- A program built around your goals, not just your pain — whether that’s a full round of golf, kneeling in the garden, or playing with grandchildren without a second thought.
- Progressive loading matched to your joint, adjusted session to session as your capacity changes, rather than a static plan.
- Funding support, including guidance on Medicare Chronic Disease Management (EPC) plans and DVA eligibility, alongside private options.
- Ongoing clinical review, so the program keeps moving with you rather than staying fixed at week one.
If osteoarthritis has quietly taken activities off your table — and you’d like to understand what a program built specifically around your joint could look like — an initial assessment is the place to start.
FAQ
Q: Is exercise safe for osteoarthritis? A: Yes. Exercise is recommended as first-line treatment for knee and hip osteoarthritis in current clinical guidelines, ahead of surgery and often alongside or instead of medication.
Q: Can exercise reverse osteoarthritis? A: Exercise doesn’t reverse the underlying joint changes, but it reliably reduces pain and improves function and quality of life, and can reduce or remove the need for joint replacement surgery in many people.
Q: What is the best exercise for knee osteoarthritis? A: There’s no single best exercise — an effective program is progressive, supervised, and matched to the individual’s current joint capacity, typically combining strength, movement control, and general activity.
Q: Should I exercise if my joint hurts? A: Some discomfort during appropriately loaded exercise is normal and expected, and doesn’t mean damage is occurring. Sharp or worsening pain, swelling, or symptoms that don’t settle should be reviewed by a practitioner.
Q: Do I need a GP referral to see an Exercise Physiologist for arthritis? A: No referral is required to book an initial assessment, though a GP referral may make you eligible for a Medicare rebate under a Chronic Disease Management plan.
