Arthritis is one of the most common reasons people over fifty stop exercising. It is also one of the strongest reasons to begin resistance training — because the research on progressive resistance training and arthritis pain is unambiguous: movement reduces it, and rest makes it worse.
The advice most commonly given to the person with arthritis is to rest the affected joints and avoid activities that provoke pain. This advice is understandable, well-intentioned, and — with respect to resistance training specifically — wrong. The research on progressive resistance training in people with osteoarthritis and rheumatoid arthritis consistently shows that appropriately applied resistance exercise reduces pain, improves joint function, reduces disability, and slows the progression of joint damage. The joint that is protected from all loading continues its decline. The joint that is progressively loaded within a pain-appropriate range improves its supporting musculature, its synovial fluid circulation, and its functional capacity.
The mechanism is not complicated. The pain of arthritis is produced in part by weak muscles that fail to adequately support the joint — allowing abnormal loading patterns that stress the articular cartilage and synovial membrane. Strengthening the muscles that cross an arthritic joint reduces the abnormal loading on the joint surface, improves the shock-absorbing capacity of the periarticular musculature, and distributes the forces of daily activity more evenly across the joint surface. The muscle is the treatment. Resistance training builds the muscle.
This page covers both osteoarthritis — the degenerative joint disease that affects articular cartilage — and rheumatoid arthritis — the inflammatory autoimmune condition. The evidence for resistance training is strong for both, the mechanisms differ in emphasis, and the specific considerations for each are worth understanding before beginning a programme.
This page covers resistance training considerations for osteoarthritis and rheumatoid arthritis. It is not medical advice. Anyone with rheumatoid arthritis should consult their rheumatologist before beginning resistance training — particularly regarding training during flare periods, when joint inflammation is active and loading should be modified or suspended. For osteoarthritis, most people can begin a carefully progressed resistance training programme without specific medical clearance, but any joint pain that is severe, rapidly worsening, accompanied by significant swelling, or producing symptoms beyond the affected joint warrants medical assessment before training begins.
Multiple systematic reviews and meta-analyses of progressive resistance training in people with osteoarthritis — particularly knee and hip osteoarthritis, which account for the majority of arthritis-related disability — consistently find that resistance training reduces pain scores by twenty to fifty percent, improves functional performance on walking, stair-climbing, and sit-to-stand tests, and reduces self-reported disability. These improvements are produced at training frequencies and intensities that are achievable by the over-50 adult with arthritis and do not require the specialised facilities or supervised settings that many clinical guidelines assume.
Each finding addresses a specific aspect of arthritis management. Together they establish resistance training as a primary treatment — not a complementary one.
Meta-analyses of resistance training in knee osteoarthritis consistently show pain reduction of twenty to forty percent from baseline across training periods of eight to twenty-four weeks. The pain reduction is clinically meaningful — comparable in magnitude to the pain reduction produced by non-steroidal anti-inflammatory medications in mild to moderate osteoarthritis, and produced without the gastrointestinal and cardiovascular side effects that long-term NSAID use carries. The effect is maintained with continued training and reduces when training stops.
Functional performance measures — the time to walk a set distance, the number of chair-stands in thirty seconds, stair-climbing speed — consistently improve with progressive resistance training in people with osteoarthritis. These functional improvements reflect the practical daily life benefit of the training rather than its laboratory measurement, and they are the outcomes most directly relevant to the over-50 person with arthritis whose primary concern is maintaining the independence and capability that arthritis threatens.
Contrary to the intuitive concern that loading an arthritic joint damages cartilage further, research using MRI imaging consistently shows that progressive resistance training at appropriate loads maintains articular cartilage thickness and in some studies produces modest improvements in cartilage quality. The mechanism is the synovial fluid circulation that joint movement promotes — cartilage is avascular and depends on movement-driven synovial fluid diffusion for its nutrition. Rest reduces this nutritional supply. Appropriate movement maintains it.
Progressive resistance training in rheumatoid arthritis reduces inflammatory markers — including CRP and ESR — alongside the pain and functional improvements seen in osteoarthritis. This anti-inflammatory effect is produced through the myokine secretion of contracting muscle and the systemic anti-inflammatory effects of regular exercise more broadly. Crucially, resistance training does not exacerbate joint inflammation in rheumatoid arthritis when performed outside of active flare periods — the historical concern that loading inflamed joints worsens the condition has not been supported by the research evidence.
Long-term studies of resistance training in people with osteoarthritis show that consistent progressive exercise slows the radiographic progression of joint space narrowing — the X-ray measure of cartilage loss over time. People with knee osteoarthritis who exercise consistently show less joint space narrowing at five and ten year follow-up than sedentary counterparts — suggesting that the training is not merely managing symptoms but actually slowing the underlying disease process through the mechanisms of cartilage nutrition and periarticular muscle support.
Several large cohort studies have found that regular physical activity — including resistance training — is associated with reduced rates of total knee and hip replacement in people with osteoarthritis. The mechanism is the combination of pain reduction, functional improvement, and disease progression slowing that makes the joint replacement threshold less frequently reached in physically active people. For the over-50 adult with mild to moderate osteoarthritis, this represents the most compelling available evidence that exercise is genuinely altering the trajectory of the condition.
The modifications below address the four most commonly arthritic joints in the over-50 strength training population — the knee, the hip, the shoulder, and the hands and wrists. Each modification reduces the loading stress on the affected joint while maintaining as much of the training stimulus as the unaffected parts of the programme can deliver. The principle throughout is the same as the injury management page: train what is not affected, modify what is, and maintain the habit and the progressive stimulus that the unmodified parts of the programme continue to provide.
Each modification reduces joint stress while maintaining training stimulus. Pain-free range of motion is the criterion throughout.
Reduce squat depth to the pain-free range rather than eliminating the squat entirely. A box squat to a height above parallel that is pain-free maintains the quadriceps and glute stimulus while removing the end-range loading that provokes pain. The Romanian deadlift is typically well tolerated by arthritic knees because the knee joint is not the primary mover — continue without modification or with a slight reduction in range if any knee discomfort arises. The leg press at a pain-free range is a useful squat alternative when the squat range cannot be progressed. Add terminal knee extensions with a resistance band — the VMO activation exercise that specifically strengthens the quadriceps component most important for knee joint support.
Hip osteoarthritis typically limits the end range of hip flexion and internal rotation — the deep squat position and the fully extended hip hinge. Reduce squat depth to parallel or above and reduce the Romanian deadlift range to the point where hip flexion is comfortable. The conventional deadlift may be more comfortable than the Romanian deadlift for some hip arthritis presentations — the slightly more upright torso and the reduced end-range hip flexion of a conventional pull from blocks or a trap bar may allow loading that the full Romanian range does not. All upper body pressing and pulling movements continue without modification — the hip is not involved in any upper body compound movement.
Shoulder arthritis most commonly limits overhead range and external rotation — the overhead press and the behind-the-neck positions are typically most aggravating. Replace the overhead press with a landmine press — pressing a barbell anchored at the floor at a forty-five degree angle, which achieves the shoulder loading in a partially overhead position that most arthritic shoulders tolerate when the full overhead position does not. Dumbbell pressing at incline angles is also better tolerated than full overhead pressing. Pulling movements — rows and lat pulldowns — are typically well tolerated because they operate in the plane of the shoulder joint rather than at its end range. All lower body training continues without modification.
Hand and wrist arthritis affects grip-dependent movements — the deadlift, the barbell row, the farmer's walk, and pressing movements that require wrist extension. Lifting straps remove the grip demand from deadlifts and rows — the wrist remains in a neutral position and the strap transfers the load to the forearm rather than the fingers and wrist joints. Hex dumbbells rather than straight barbells allow a neutral wrist position in pressing movements. The farmer's walk can be replaced with a rack carry — the weight held at shoulder height in the rack position removes the hanging grip load. Neutral grip attachments for cable rows keep the wrist in its strongest and least painful position throughout the pulling range.
Two sessions per week. Extended warm-up — fifteen to twenty minutes with specific attention to the arthritic joint. Pain-free range of motion is the non-negotiable criterion for every exercise at every session.
Each principle addresses a specific aspect of training with an arthritic joint. Together they constitute the approach that produces the pain reduction and functional improvement the evidence documents.
The joint that hurts because it is arthritic will hurt more if it is not trained. The musculature around an arthritic joint is the joint's primary protection — and that musculature is only built by the resistance training that loads it progressively. Movement is not what arthritis makes painful. Weak muscles allowing abnormal joint loading is what arthritis makes painful. Resistance training addresses the cause. Rest manages the symptom while the cause worsens.

The Minimum 12
Twelve fundamental compound movements — each of which can be modified for the specific joint affected by arthritis, none of which requires joint pain to produce training benefit, all of which build the periarticular musculature that is the most effective available protection for the arthritic joints they load.
