Exercise With Arthritis After 60: What the Research Shows and How to Train Safely

The instinct to rest arthritic joints is understandable. The research says it's often counterproductive. Here's what we know about exercise, arthritis, and how to move well despite — and because of — joint disease.

Regular exercise is one of the most effective treatments for osteoarthritis in older adults. Research consistently shows that appropriate physical activity reduces arthritis pain, improves joint function, builds the muscle that protects arthritic joints, and often reduces the need for pain medication — without worsening joint damage when performed correctly.

Arthritis affects more than 58 million Americans, with prevalence increasing sharply with age. By age 65, approximately 50% of adults have some degree of osteoarthritis in at least one joint.

The most common response to arthritis pain is rest — reducing activity to avoid the discomfort that movement can produce. This response is understandable but, in most cases, counterproductive. The research is consistent and striking: appropriate exercise reduces arthritis symptoms, improves function, and may slow disease progression. Inactivity does the opposite.

This article covers what exercise does for arthritic joints, how to train safely with arthritis, and what modifications make effective training possible even with significant joint involvement.

Understanding Osteoarthritis

Osteoarthritis (OA) is the most common form of arthritis — a degenerative joint disease characterized by the breakdown of articular cartilage, the smooth tissue that cushions the ends of bones in joints. As cartilage breaks down, bones can rub against each other, causing pain, swelling, and reduced range of motion.

OA commonly affects the knees, hips, hands, and spine. It is associated with aging, prior joint injury, excess body weight (which increases joint loading), and genetic factors.

A key misconception about OA is that it is caused by exercise or that exercise makes it worse. The evidence does not support this. Appropriately designed physical activity does not accelerate cartilage loss — and the indirect benefits of exercise (reduced body weight, improved muscle strength, better joint mechanics) may actually protect arthritic joints.

What Does Exercise Do for Arthritic Joints?

Reduces pain

Multiple high-quality trials and systematic reviews have found that regular exercise significantly reduces pain in osteoarthritis — often to a degree comparable to over-the-counter pain medications.

🔬 Research: A 2015 Cochrane review examined 54 randomized controlled trials of exercise for knee osteoarthritis. It found that exercise significantly reduced pain and improved function, with effect sizes comparable to non-steroidal anti-inflammatory drugs (NSAIDs) for mild to moderate OA — but without the gastrointestinal and cardiovascular side effects associated with long-term NSAID use.

The mechanisms by which exercise reduces OA pain include: improved neuromuscular control reducing joint loading during movement; muscle strengthening that better supports and cushions the joint; reduction in inflammatory markers; and improved synovial fluid circulation (synovial fluid nourishes cartilage and reduces friction).

Improves function

Pain is one dimension of arthritis impact; functional limitation is another. Exercise consistently improves both objective measures of function (timed walking tests, stair climbing tests, range of motion) and subjective quality of life measures in people with OA.

This functional improvement has direct implications for independence. The ability to rise from a chair, walk to the store, and manage daily tasks is more dependent on muscular strength and movement quality than on joint structure alone — and these are precisely what exercise develops.

Builds protective musculature

Muscles surrounding arthritic joints act as shock absorbers — absorbing the forces that would otherwise be transmitted directly to joint surfaces. Weak muscles mean more joint loading and more pain. Stronger muscles mean less joint loading and less pain.

This is particularly well-documented in knee OA: quadriceps weakness is both a risk factor for knee OA development and a predictor of OA progression. Building quadriceps strength is one of the most evidence-backed interventions for knee OA management.

Supports body weight management

Body weight directly influences joint loading. For the knee specifically, each pound of body weight creates approximately 4 pounds of force at the knee joint during walking. A 10-pound weight reduction reduces knee joint loading by approximately 40 pounds per step — thousands of pounds of cumulative force reduction per day of walking.

Exercise supports body composition improvements that reduce this loading — both through calorie expenditure and through muscle building that improves metabolic rate.

Which Types of Exercise Are Best for Arthritis?

Resistance training

Progressive resistance training is the most important exercise modality for arthritis management. Building the muscles that surround arthritic joints reduces joint loading, improves joint stability, and directly addresses one of the primary mechanisms of OA pain.

For adults with knee OA, exercises that build quadriceps, hamstrings, and hip abductors are particularly valuable. For hip OA, hip abductor and extensor strengthening is key. For shoulder and hand OA, appropriate pressing and gripping progressions build the protective musculature without excessive joint stress.

Low-impact aerobic activity

Low-impact aerobic activities — swimming, cycling, water aerobics, elliptical training, and walking — provide cardiovascular benefits, support body composition, and produce anti-inflammatory effects without the high-impact loading that can exacerbate arthritic pain.

Swimming and water-based exercise are particularly valuable for adults with severe OA, as buoyancy reduces joint loading significantly while still allowing effective cardiovascular and muscular conditioning.

Range of motion and flexibility work

Arthritic joints benefit from regular movement through their available range of motion. Sustained immobility leads to stiffness, contracture, and further loss of function. Gentle range-of-motion exercises and stretching maintain joint mobility and reduce morning stiffness — one of the most common and disabling symptoms of OA.

How to Train With Arthritis: Practical Principles

Distinguish pain from discomfort

Not all pain signals during exercise indicate damage. Arthritic joints produce discomfort during movement that is, in most cases, not a sign that damage is occurring. Learning to distinguish productive discomfort (mild to moderate aching during and after exercise that resolves within 24 hours) from harmful pain (sharp, acute pain during movement, or pain that worsens significantly after exercise and persists for more than 24 hours) is critical.

The '24-hour rule': if pain from exercise is no worse 24 hours after the session than before, the exercise was appropriate. If it is significantly worse, reduce the load or intensity in the next session.

Warm up thoroughly

Arthritic joints benefit more from thorough warm-up than non-arthritic joints. The initial stiffness of an arthritic joint — particularly pronounced in the morning or after sitting — responds to gentle, progressive movement that increases synovial fluid distribution and raises tissue temperature. Rushing into loaded exercise before joints are adequately prepared increases pain and injury risk.

Modify, don't avoid

Almost every exercise can be modified to reduce joint stress while preserving the training stimulus. Knee pain with squatting may respond to reduced depth, box squats, or goblet squats rather than barbell back squats. Hip pain with deadlifting may respond to elevated starting position (using blocks) or switching to a trap bar. Shoulder pain with pressing may respond to neutral grip or reduced range of motion.

The goal is to find the version of the movement that provides adequate stimulus without causing significant pain — and to progress as pain tolerance and strength improve.

Work with coaches who understand modification

This is perhaps the most important practical principle. Arthritic adults training without experienced coaching are left to navigate modification decisions that genuinely benefit from professional expertise. Coaches at Pace who work with Forever Fit members have training in working around common limitations and can make real-time adjustments that protect joints while preserving effective training.

📌 One of the most consistent things we hear from Forever Fit members who came to us managing significant arthritis is that appropriate training reduced their pain — not just while training, but in daily life. Building the surrounding musculature and improving movement mechanics often produces lasting pain reduction that no passive intervention achieves.

Working With Your Healthcare Team

Exercise for arthritis should generally be discussed with the healthcare providers managing your arthritis — particularly if you have severe OA, recent joint replacement, or significant symptoms. Most physicians and physical therapists are strongly supportive of appropriate exercise; a physical therapy consultation before beginning a strength training program can also provide useful individualized guidance on movement modifications.

At Pace, we actively coordinate with healthcare providers when members request it, and our Pace Health clinic provides clinical evaluation that can help bridge the gap between medical management and fitness training.

Frequently Asked Questions

Will exercise wear down my cartilage faster?

The evidence does not support this. Studies examining the cartilage of older adults who have been physically active throughout their lives show no accelerated cartilage loss compared to sedentary peers. The loading that exercise provides stimulates cartilage metabolism and may actually support cartilage health. What damages cartilage is high-impact trauma and severe joint malalignment under load — not appropriate, well-coached progressive exercise.

Should I exercise when my arthritis is flaring?

During an active flare — characterized by increased swelling, warmth, and acute pain — reducing training intensity and avoiding movements that load the affected joint is appropriate. Gentle range-of-motion work and low-impact activity that doesn't stress the inflamed joint can be continued. After the flare resolves, returning to progressive training is appropriate and beneficial.

Is swimming better than lifting for arthritis?

Swimming provides cardiovascular benefits with very low joint impact — valuable for adults with severe OA who cannot tolerate weight-bearing exercise. However, it doesn't build the resistance-against-gravity strength that is most protective of arthritic joints and bone density. For most adults with mild to moderate OA, a combination of progressive resistance training with appropriate modification and low-impact cardio is superior to swimming alone.
