Exercise for Arthritis: Moving Well With Achy Joints

ARTHRITIS AND EXERCISE · ACTIVE LIVING

When your knees ache on the stairs or your hands feel stiff in the morning, resting the joint can seem like the kind thing to do. For most people with arthritis, the evidence points the other way: the right kind of movement, built up patiently, is one of the most reliable ways to feel better.

Exercise for arthritis is not a single workout. It is a mix of joint-friendly cardio, strength work and gentle range-of-motion practice, adjusted to how your joints feel on a given day. This guide covers what the major guidelines recommend, which activities suit sore joints, how to read pain signals and how to structure your first month. It focuses mainly on osteoarthritis; if you have rheumatoid arthritis or another inflammatory condition, your care team can help you adapt the advice.

Why exercise for arthritis works

Arthritis is far more common in midlife than many people realize. A CDC analysis of national survey data from 2019 to 2021 estimated that about 53.2 million US adults, or 21.2 percent, had been diagnosed with arthritis. The figure was 26.0 percent among adults aged 45 to 64 and 47.3 percent among those 65 and older, and diagnosed arthritis was more common in women than in men.

The same report notes that physical activity is important for managing arthritis-related pain and improving physical function, yet many adults with arthritis do not meet national activity guidelines. According to the CDC’s guidance on physical activity and arthritis, regular activity can reduce joint pain and improve function and mood. Stronger muscles also help absorb and spread the load that would otherwise land on the joint itself.

A common worry is that exercise will wear joints out faster. The research on running offers a useful check on that fear. A 2017 meta-analysis in the Journal of Orthopaedic and Sports Physical Therapy found that hip or knee osteoarthritis was reported in 3.5 percent of recreational runners, compared with 10.2 percent of sedentary non-runners and 13.3 percent of competitive runners. The authors cautioned that the data cannot prove cause and effect, but the pattern does not suggest that moderate, regular activity is the enemy of healthy joints.

What the major guidelines recommend

The 2019 American College of Rheumatology and Arthritis Foundation guideline for osteoarthritis of the hand, hip and knee, published in Arthritis Care and Research, gives exercise its strongest level of recommendation for all three sites. It also strongly recommends self-management programs, tai chi for hip and knee osteoarthritis, and weight loss for hip and knee osteoarthritis when appropriate. Balance exercises and, for the knee, yoga receive a conditional recommendation.

The guideline did not name one best type or dose of exercise. It advises making the plan as specific to the person as possible and notes that programs often work better when supervised, for example by a physical therapist or in a class. For weekly targets, CDC points adults with arthritis to the same baseline as everyone else:

• At least 150 minutes a week of moderate-intensity aerobic activity, which can be built from bouts as short as 5 or 10 minutes.
• Muscle-strengthening activities on at least 2 days a week, using weights or resistance bands that do not cause joint pain.
• Balance activities woven into the weekly mix, particularly for older adults.

If those numbers feel far away, CDC is explicit that you can start with just 5 minutes and add a little at a time. The weekly total matters more than how you slice it.

Choosing joint-friendly activities

“Joint-friendly” usually means activities that move you steadily without repeated pounding or sudden twisting. CDC’s examples include brisk walking, cycling, light gardening, dancing, tai chi, swimming and water exercise. The best choice is the one you will repeat.

Activity	Why it suits sore joints	Good starting point
Brisk walking	Needs no equipment and is easy to scale by distance, pace and terrain.	10 minutes on flat ground, most days
Cycling or a stationary bike	Moves the knees and hips through a smooth arc while the seat carries your body weight.	10 to 15 minutes at an easy, conversational effort
Swimming or water exercise	Water supports the body, so many people can move more freely than on land.	A short class or 15 minutes of walking laps in the shallow end
Tai chi	Slow, controlled weight shifts build leg strength and balance together.	One beginner class or video session a week, then more

Walking deserves special mention because it is so accessible. The Arthritis Foundation’s Walk With Ease program runs for six weeks and encourages participants to walk three times a week; it has been shown to reduce pain and improve balance and walking pace. If you want ideas for pace and step targets, see Stature™’s guide to walking for health. For a slower, flowing option that the rheumatology guideline singles out, our beginner’s guide to tai chi walks you through a first session.

Strength and range of motion: your joints’ support system

Mayo Clinic’s guidance on arthritis and exercise describes three complementary types of exercise. Range-of-motion work keeps joints moving and eases stiffness, and most of these movements can be done every day. Strengthening builds the muscle that supports the joints and should typically be done at least two days a week, covering all the major muscle groups. Aerobic exercise raises your heart rate and supports overall fitness and weight management.

For the knee, that often means working the thigh and hip muscles with movements such as sit-to-stands from a chair, step-ups onto a low step, bridges and band-resisted side steps. For the hip, add glute bridges and side-lying leg raises. Choose a resistance that lets you finish each set with good control and without sharp pain; you can progress later, and our guide to choosing sets and reps explains how.

Mayo Clinic also suggests warming up with 5 to 10 minutes of range-of-motion movement before strength or aerobic work. Some people find that warm, not hot, packs or a warm shower for about 20 minutes beforehand loosen stiff joints, and that ice for up to 20 minutes afterward helps if a joint tends to swell. A short dynamic warm-up does the same job of easing you into the session.

How to tell normal discomfort from a warning sign

Many people with arthritis live with some baseline ache, and that alone is not a reason to avoid exercise. CDC notes that some pain, stiffness or swelling is normal when you start a new program, but that joint pain from activity should improve over time; if it does not, contact your health care provider. The goal is a level of effort that leaves your joints feeling no worse, or better, by the following day.

A practical yardstick used by Arthritis Australia is the two-hour rule: if you have extra or unusual pain for more than two hours after exercising, you did too much, so slow down or do less next time. Mayo Clinic adds that sharp pain, or pain that is worse than your usual joint pain, may mean something is wrong, and that swelling or a change in skin color around a joint is a signal to ease off.

• Usually fine: a mild, familiar ache during or after activity that settles within a couple of hours.
• Adjust next time: extra pain that lingers beyond two hours, or stiffness that is worse the next morning.
• Stop and check in with a clinician: sharp or unusual pain, a joint that is red, hot or newly swollen, giving way, or symptoms that keep getting worse.

During a flare, Arthritis Australia advises resting more and avoiding vigorous exercise on any joint that is red, hot, swollen or painful. It can also help to schedule activity for the time of day when your pain and stiffness are usually lowest.

A sample first month

This outline shows one way to build from very little toward the weekly guidelines. Treat it as a template, and slow the pace if your joints ask you to.

Week	Aerobic	Strength	Range of motion and balance
1	10 minutes of walking, cycling or water exercise on 3 days	1 set of 3 to 4 exercises on 2 days	5 minutes of gentle joint circles daily
2	15 minutes on 3 to 4 days	1 to 2 sets on 2 days	Add a supported single-leg stand
3	20 minutes on 4 days, or two 10-minute bouts	2 sets on 2 days, slightly more resistance	Try one tai chi or gentle yoga session
4	20 to 30 minutes on 4 to 5 days	2 sets on 2 to 3 days	Daily range of motion, balance practice 2 to 3 days

By the end of the month, many people are close to the 150-minute mark without a single punishing workout. From there, change one thing at a time: a few more minutes, a brisker pace or a little more resistance.

Talk with your doctor before starting or stepping up exercise if you have heart disease, diabetes, kidney disease, new or unexplained symptoms, a recent injury or surgery, or if you are pregnant. If a joint has been replaced or injected recently, ask what movements and loads are appropriate for now.
