The case for movement

This might sound counterintuitive when your joints hurt, but the evidence is clear: regular exercise reduces pain and improves function in virtually all forms of arthritis — including rheumatoid arthritis, osteoarthritis, psoriatic arthritis, ankylosing spondylitis, and gout. Decades of research consistently show that people who stay active have less pain, better mobility, and improved quality of life compared to those who rest and avoid movement.

The old advice to “take it easy” and protect your joints by not using them was well-intentioned but wrong. Inactivity leads to muscle weakness, joint stiffness, deconditioning, and fatigue — all of which make arthritis symptoms worse, not better.

Motion is lotion

Your joints are lined with synovial membrane that produces synovial fluid — a viscous, nutrient-rich liquid that lubricates and nourishes cartilage. Here’s the thing: synovial fluid doesn’t circulate on its own. It needs movement to distribute across joint surfaces. When you sit still for hours, that fluid isn’t doing its job, and your joints stiffen up.

This is why your morning stiffness improves once you start moving. It’s why sitting through a long movie makes your knees ache. And it’s why consistent daily movement — even on days you don’t feel like it — keeps joints more comfortable over time.

What kinds of exercise work best

There is no single “best” exercise for arthritis. The best exercise is the one you’ll actually do consistently. That said, these modalities all have strong evidence behind them:

Walking — the simplest, most accessible option; even 10-minute walks count toward your weekly total
Swimming and aquatic therapy — water supports your body weight, reducing joint stress while providing resistance; warm water pools are especially helpful for stiffness
Cycling — stationary or outdoor; low-impact and excellent for knee and hip mobility
Yoga and tai chi — improve flexibility, balance, and body awareness; modified poses are available for every joint limitation
Resistance training — building muscle around affected joints provides stability and reduces load on the joint itself; this is not optional — it’s one of the most effective interventions we have

A well-rounded routine includes some combination of aerobic activity, strengthening, and flexibility/range-of-motion work.

Starting when you’re deconditioned

If you haven’t exercised in months or years — or if you’ve been in a prolonged flare — the idea of “150 minutes per week” can feel overwhelming. Ignore that number for now.

Start with 5–10 minutes of gentle walking or movement, once or twice a day
Expect some discomfort — muscle soreness and mild joint aching after exercise are normal, especially when starting; this is not the same as joint damage
The “two-hour rule” is a useful guideline — if your pain is notably worse two hours after exercise compared to before, you did too much; dial it back next time
Increase gradually — add 5 minutes per session every 1–2 weeks as tolerated
Consistency matters more than intensity — four 15-minute walks per week beats one grueling hour on the weekend

When to modify — flare management

Flares happen. They don’t mean you stop moving entirely.

Gentle range-of-motion exercises are appropriate even during active flares — move each affected joint through its comfortable range without resistance
Avoid loading inflamed joints — if your knee is hot and swollen, skip the squats and go for a gentle swim or upper-body work instead
Reduce intensity and duration, not frequency — keep showing up, just do less
Ice after activity can help manage post-exercise swelling during flares
Listen to your body, but don’t let fear of pain stop all movement — complete rest during flares leads to faster deconditioning and a harder road back

Sometimes you need expert guidance to get started safely or push through a plateau. We refer to physical therapy when:

You’re unsure how to exercise safely with specific joint limitations
You’ve had joint surgery and need structured rehabilitation
You have significant muscle weakness or balance concerns
You’re dealing with persistent pain that hasn’t responded to your current activity level
You need a customized home exercise program tailored to your condition

A good physical therapist who understands inflammatory arthritis — not just wear-and-tear osteoarthritis — is worth their weight in gold. Ask us for a referral if you’re interested.

The goal

The target is the same as the general population: 150 minutes per week of moderate-intensity aerobic activity, plus two or more days of muscle-strengthening activities. Moderate intensity means you can talk but not sing during the activity.

This is a goal, not a starting point. If you’re currently at zero, getting to 30 minutes per week is a meaningful improvement. Progress from there.

The bottom line: arthritis is not a reason to stop moving — it’s one of the best reasons to start.
