Exercising With Rheumatoid Arthritis: What Is Safe and What Actually Helps

Rheumatoid arthritis is an autoimmune condition in which the immune system attacks the lining of the joints, producing inflammation, pain, swelling and, if uncontrolled, joint damage. It differs fundamentally from osteoarthritis, which is a wear and load-related condition, and it is treated with disease-modifying drugs rather than with exercise alone.

The reason exercise matters alongside that medical treatment is what the disease does around the joints. Inflammation drives muscle loss, sometimes substantial, and that loss compounds the disability the joints themselves cause. Rheumatoid arthritis also raises cardiovascular risk, and reduced activity makes that worse.

Exercise addresses both. Building muscle protects joints by sharing load, and cardiovascular training addresses a risk that the disease itself elevates.

The 2018 EULAR recommendations on physical activity in people with inflammatory arthritis set the standard targets: at least 150 minutes of moderate-intensity activity per week, plus strength training on at least two days a week.

On strength training specifically, the evidence indicates that appropriately prescribed resistance work reduces pain and inflammatory markers, improves body composition and function, and lowers cardiovascular and other comorbidity risk in people with rheumatoid arthritis. Well-designed strength training does not accelerate joint damage when it is prescribed and monitored properly, which is the concern that kept the old advice in place.

EULAR’s position in 2018 was explicit that strength training should form part of standard treatment for people with rheumatoid arthritis rather than being an optional extra for the well-controlled.

• Strength, twice a week. Major muscle groups, resistance you can control for eight to twelve repetitions, progressed over weeks. Machines and bands are useful where grip is limited by hand involvement.
• Cardiovascular work, 150 minutes a week of something moderate. Walking, cycling and swimming are all low-impact and easy to sustain.
• Range of movement daily, particularly for hands, wrists and shoulders, which stiffen fastest.
• Balance work if the feet or ankles are involved, since foot deformity and altered sensation change stability.
• Warm up longer than you think. Stiff inflamed joints need more preparation, and morning stiffness means later sessions often go better.

Progression is the part most often missed. Doing the same light exercises for a year builds nothing, and the benefits in the trials come from resistance that increases.

Flares are part of the condition and they need a plan rather than an abandoned programme.

• During an active flare in a joint, reduce load through that joint and keep gentle range of movement going. Complete rest of the joint stiffens it and complete rest of the body loses ground everywhere else.
• Keep training what is unaffected. A flaring wrist does not stop leg work. This is the single most useful habit for maintaining capacity across years of a fluctuating condition.
• Come back in stages. Return at roughly half the load you left at and build over one to two weeks.
• Judge by the next day. Increased joint swelling, heat or pain lasting into the following day means the session was too much. Muscle soreness alone is fine.
• Frequent or severe flares are a rheumatology conversation about disease control rather than an exercise problem.

Rheumatology manages the disease itself: diagnosis, disease-modifying drugs, biologics, monitoring and flare management. This is the foundation, and exercise does not substitute for it.

Physiotherapy handles function: the strength programme, joint range, walking and balance, pain management strategies, and returning to specific activities. It also covers the mechanical problems that arrive alongside the disease, such as tendon pain and altered gait.

Occupational therapy covers hand function, splinting, joint protection in daily tasks and workplace adaptation.

Podiatry matters more in rheumatoid arthritis than most people expect, since foot involvement is common and early.

Our article on arthritis and MSK specialists covers who treats what across the different types of arthritis.

What has changed in clinic is who arrives asking about strength training. Uckfield Community Hospital on Framfield Road runs rheumatology outpatient clinics, so a good number of people in the area are seen locally for the disease itself, and more of them now come out of those appointments having been told to exercise rather than to rest. What they are usually missing is any specification of what that means.

The clinical point is that the gap between "stay active" and the EULAR targets is enormous. Two strength sessions a week, at a resistance that increases over months, is a different prescription from a daily walk, and it is the one that addresses the muscle loss inflammation causes. Getting there with rheumatoid arthritis means choosing exercises that work around the joints currently involved, using machines or bands when grip is the limiting factor, and having a rule for what happens during a flare so the programme survives one instead of ending at it.

Assessment and a programme built around which joints are involved sits within musculoskeletal pain and injury care.

Will exercise damage my joints?
Appropriately prescribed and monitored strength training does not accelerate joint damage, and it protects joints by building the muscle around them.

Should I exercise during a flare?
Reduce load through the flaring joint, keep gentle movement going, and keep training everything else. Stopping entirely costs ground that takes weeks to regain.

Is swimming better than weights?
They do different jobs. Swimming is excellent cardiovascular work and easy on joints. Building muscle needs resistance, and both belong in the week.

Can exercise replace my medication?
No. Disease-modifying treatment controls the underlying disease. Exercise addresses function, muscle, pain and cardiovascular risk alongside it.

Where do I start if I have not exercised in years?
With an assessment that identifies which joints are involved and what they currently tolerate, then a programme starting below that level and progressing.
