Arthritis and exercise might seem like an unlikely pairing. When joints are stiff, swollen, or painful, the instinct is to protect them by moving less. But decades of clinical research have reversed this intuition in a decisive way: for both of the most common forms of arthritis — osteoarthritis (OA) and rheumatoid arthritis (RA) — regular, appropriately chosen exercise is not merely safe but is classified as a first-line treatment in major clinical guidelines.
The 2019 ACR/Arthritis Foundation guideline (PMID 31908149) offers a strong recommendation for both aerobic and resistance exercise across all types of OA. EULAR (European League Against Rheumatism) similarly recommends physical activity as a core component of RA management during periods of remission. The evidence base is not thin or contested: exercise reduces pain, improves joint function, maintains muscle mass that protects joints, and supports mental health in people living with arthritis.
The challenge — and this is where good guidance matters — is that the wrong exercise at the wrong time can cause genuine harm. Running through an RA flare can worsen joint damage. Deep squats without guidance can aggravate knee OA. The goal of this guide is to help you understand which exercises work, which to avoid, and the critical distinction between OA and RA that shapes everything about timing and approach.
This article covers the full landscape: understanding the two main types of arthritis from an exercise perspective, the safest and most effective movement categories, what to avoid, and how to structure a sustainable routine that protects your joints while building the strength and mobility that makes daily life easier.
OA vs. RA: Two Conditions, Two Exercise Logics
Understanding the difference between osteoarthritis and rheumatoid arthritis is the single most important step in building an appropriate exercise approach. They share the word “arthritis” and the symptom of joint pain, but their underlying mechanisms are entirely different — and this difference determines the exercise rules.
Osteoarthritis (OA) is a degenerative condition caused by the breakdown of articular cartilage — the smooth tissue that covers the ends of bones where they meet in a joint. As cartilage wears down, bones can eventually rub against each other, causing pain, stiffness, and reduced range of motion. OA is the most common form of arthritis, predominantly affecting weight-bearing joints (knees, hips) and the hands. It is worsened by excessive mechanical loading — particularly high-impact, repetitive activities — and by obesity (due to the mechanical load on weight-bearing joints). Exercise for OA works by building the muscular support around the joint (reducing direct cartilage stress), improving joint lubrication through movement, and managing body weight.
Rheumatoid arthritis (RA) is an autoimmune inflammatory disease. The immune system attacks the synovial membrane lining the joints, causing inflammation, swelling, pain, and — over time — potential joint damage. Unlike OA, RA is a systemic disease that also affects other organ systems. It is characterized by periods of active inflammation (flares) and relative remission. The exercise logic for RA is fundamentally gated by inflammatory status: exercise during remission is beneficial and recommended; exercise during an active flare affecting a joint is contraindicated for that joint, as it can worsen inflammatory damage.
This distinction — OA’s continuous exercise tolerance versus RA’s flare-dependent approach — is the single most important piece of information in this article. If you have RA and your joints are hot, swollen, and acutely tender, those joints need complete rest until the flare has subsided. Any other guidance is secondary to this principle.
One practical clarification for people newly diagnosed: the two conditions can coexist. A person with long-standing RA may also develop secondary OA from cumulative joint damage, and an older adult with OA can experience inflammatory episodes that look flare-like. The practical implication is that the exercise plan should be built around the joints themselves — assessing each affected joint individually for warmth, swelling, range, and pain — rather than against a single diagnostic label. A knee with active RA flare needs rest even if the shoulder feels fine and is available for upper-body work. Kolasinski et al. (2020, PMID 31908149) recommend that people with OA or inflammatory arthritis work with a clinician experienced in the condition to map out which joints are “available” on any given day, and which are on a temporary rest protocol. This joint-by-joint mental model keeps training alive during difficult weeks without pushing inflamed tissue through damage.
The Evidence: Why Exercise Works for Arthritis
For OA, the evidence is particularly robust. Exercise therapy for chronic musculoskeletal pain works partly by altering central pain sensitization — changing how the nervous system processes and amplifies pain signals from affected joints (Nijs et al., 2015, PMID 26988013). This means exercise’s benefits extend beyond simple mechanical improvements into neurological recalibration of pain perception. Patients who exercise consistently report improved pain scores not just during activity but at rest.
Resistance training, as Westcott (2012, PMID 22777332) comprehensively reviewed, produces significant improvements in musculoskeletal health across all ages. For arthritis specifically, stronger muscles around a joint serve as a dynamic shock-absorbing system, redistributing forces that would otherwise concentrate on damaged cartilage or inflamed synovial tissue. The analogy is instructive: a well-sprung suspension system protects the road surface below; strong muscles protect the joint surfaces within.
For RA, the relationship is more nuanced but equally positive during appropriate periods. Resistance training during remission does not worsen RA and is associated with improved function, reduced fatigue (a major RA symptom), and better quality of life. Aerobic exercise has additional benefits including cardiovascular risk reduction, which is elevated in RA due to systemic inflammation.
The ACSM position stand (PMID 21694556) provides the evidence framework for exercise in chronic conditions: begin conservatively, progress gradually (no more than 10% volume increase per week), and monitor response. For people with arthritis, this conservatism is even more important than for healthy adults — the joints’ tolerance for loading needs to be assessed individually, not assumed.
Two practical signals help translate evidence into weekly decisions. First, use the twenty-four-hour rule: discomfort during or immediately after training that resolves within a day is acceptable and expected; discomfort that lingers past forty-eight hours, or that is worse on day two than day one, means the last session overloaded that joint. Second, track morning stiffness as a running indicator of whether the program is helping or hurting. Morning stiffness that shortens over weeks of consistent training is a strong positive signal. Morning stiffness that lengthens after starting a new exercise means the load or intensity is too high. Rausch Osthoff et al. (2018) in the EULAR recommendations note that self-monitoring of joint response is a core self-management skill for inflammatory arthritis — more useful than any external protocol because no two patients have identical tolerance profiles. A simple weekly journal tracking pain, stiffness duration, and session completed gives the clinician meaningful data at each review.
Range-of-Motion Exercises: The Foundation
For both OA and RA (during non-flare periods), range-of-motion (ROM) exercises form the foundational layer of an arthritis exercise program. They are the most universally tolerated category, involving gentle movement of affected joints through their available range without load.
Gentle joint circles. Moving the wrists, ankles, hips, and knees through slow, circular motions improves synovial fluid distribution (the joint’s natural lubricant) and maintains the available range of motion. Even a minute of gentle circles for each major joint in the morning can meaningfully reduce the stiffness many arthritis patients experience after sleep or inactivity.
Finger and hand exercises (for hand OA or RA). Making a gentle fist and slowly opening the hand fully, spreading fingers wide, and gently touching each finger to the thumb are all ROM exercises that maintain hand function. These are particularly important for people whose hand joints are affected, as grip strength and fine motor function are closely linked to independence.
Seated hip and knee mobility. From a chair, sliding one foot forward and back along the floor, lifting the knee alternately, and gently rotating the ankle — all at minimal exertion — move the lower extremity joints without compressive load.
These exercises are appropriate even during mild RA flares in unaffected joints, and can typically be performed daily. According to WHO 2020 guidelines (PMID 33239350), reducing sedentary time is beneficial for health across all populations — gentle ROM exercises throughout the day represent an evidence-supported way to achieve this while respecting joint limitations.
A useful cadence for people with arthritis is to think of ROM work as “joint hygiene” — something done daily in short bursts rather than as a single block. Three or four two-minute sessions distributed across the day often produce better results than a single eight-minute routine, because stiffness accumulates during prolonged inactivity and short mobility breaks interrupt that pattern. Morning routines are particularly valuable for RA patients because the classic “morning stiffness” of inflammatory arthritis can last thirty to sixty minutes without intervention and is reduced by gentle movement on waking. A workable morning sequence: five minutes in bed gently flexing and extending each major joint (ankles, knees, hips, wrists, elbows, shoulders, neck), followed by a warm shower and a short seated mobility routine before breakfast. Kolasinski et al. (2020, PMID 31908149) explicitly endorse flexibility and range-of-motion exercise as part of comprehensive OA management, and the pattern applies equally well to stabilising joints during RA remission. Consistency across days, even at low intensity, produces better functional outcomes than sporadic longer sessions.
Low-Impact Aerobic Exercise: Heart Health Without Joint Stress
Cardiovascular health is important for everyone with arthritis — particularly for RA patients, whose systemic inflammation elevates cardiovascular disease risk. The key is finding aerobic modalities that minimize compressive and shear forces on affected joints.
Aquatic exercise and swimming. Water buoyancy reduces effective body weight by up to 90%, nearly eliminating the compressive forces that aggravate both OA and RA joints. Aquatic exercise — whether structured water aerobics, gentle swimming laps, or simply walking in the shallow end — provides meaningful cardiovascular and muscular stimulus without the joint loading of land-based activity. Multiple studies have found aquatic exercise comparable to land-based exercise in improving pain and function for OA, with a more favorable adverse event profile. For people with significant joint involvement, aquatic exercise is often the best starting point.
Cycling. At moderate resistance with correct saddle height, cycling provides excellent cardiovascular training with minimal knee and hip stress. The circular, repetitive motion actually aids synovial fluid distribution in these joints. Recumbent cycling (on a recumbent bike) further reduces load on the lumbar spine and is easier to maintain for extended periods.
Walking. For mild-to-moderate OA (and RA in remission), regular walking is beneficial and is explicitly recommended in clinical guidelines. The key is surface choice (flat, even surfaces avoid lateral ankle and knee stress), appropriate footwear (well-cushioned, with arch support), and gradual buildup. Start with 10–15 minutes and add 5 minutes per week as tolerated. Walking in water (pool walking) is a lower-impact progression step.
Elliptical trainer. The elliptical eliminates the heel-strike impact of running while maintaining a cardiovascular intensity similar to jogging. It is well-tolerated by most people with lower-extremity OA and provides an effective aerobic workout.
A weekly aerobic framework for arthritis patients might look like this: two thirty-minute aquatic sessions, two twenty-minute cycling or elliptical sessions, and one longer walk on a weekend day — totalling roughly 130 minutes, close to the WHO minimum for cardiovascular benefit. Bull et al. (2020, PMID 33239350) confirm that cardiovascular gains scale with accumulated weekly minutes rather than with specific modality, which is liberating for people with arthritis because modality can be swapped based on which joints feel cooperative that day. On a day when the knee feels swollen, swap cycling for the pool. On a day when a shoulder is flared, keep cycling but skip the upper-body component. The underlying principle: never miss a planned session because one joint is unavailable when another reasonable option exists. Cardiovascular fitness is particularly important for RA patients because systemic inflammation raises cardiovascular disease risk above the baseline rate, making aerobic work a direct tool for reducing that excess risk rather than a peripheral wellness goal.
Resistance Training: Building the Joint’s Armor
Perhaps the most evidence-supported intervention for arthritis function is resistance training — specifically for the muscles that surround and support affected joints. The ACR/Arthritis Foundation guideline (PMID 31908149) includes resistance exercise as a strong recommendation for knee and hip OA, noting its effectiveness for pain reduction and functional improvement.
Resistance bands. Elastic resistance bands provide progressive loading without the free-weight stabilization demands that can challenge unstable joints. Band-based exercises for the lower body (clamshells, seated hip abduction, leg press against a band) and upper body (seated rows, bicep curls, shoulder press variations) allow meaningful strength training with adjustable resistance and no falling risk.
Chair-based exercises. Seated leg extensions, seated marching, and chair-assisted squats to shallow depth can build quadriceps and hip strength — the primary muscular protection for the knee and hip joints — without high compressive load. Chair squats (squatting to the edge of a chair and standing) are a functional, low-risk alternative to full squats for most OA patients.
Isometric contractions. Pressing against an immovable surface (wall press, isometric quad contractions while seated) generates significant muscular force without joint movement — uniquely appropriate when even mild joint motion is painful. Isometric exercises have demonstrated both immediate analgesic effects and longer-term strength benefits.
Wall sits (shallow). A 45° wall sit (back against the wall, thighs only partway down) loads the quadriceps and glutes isometrically without the deep knee flexion that maximizes patellofemoral and OA stress.
For RA during remission, resistance training with careful load management (starting very light and progressing slowly) has been shown to be safe and effective. However, supervision by a physiotherapist experienced in RA is strongly recommended when beginning a resistance program for the first time.
A starter resistance template for knee OA, to be progressed over eight to twelve weeks: weekly volume begins at six to eight sets total across quadriceps (leg extensions or wall sits), glutes (hip bridges or clamshells), and hip abductors (seated band abduction), performed across two non-consecutive days. Each set includes ten to fifteen controlled repetitions with a pain rating staying below three out of ten during and after the session. Westcott (2012, PMID 22777332) reviews the robust evidence that progressive resistance training in middle-aged and older adults produces meaningful gains in strength, body composition, and bone density — outcomes that directly translate into reduced joint stress during everyday tasks like climbing stairs or standing from a chair. For hand and wrist OA, a small resistance putty or a stress ball allows graded grip work without loaded movements. For shoulder OA, isometric “against the wall” pressing and scapular retractions offer strength exposure without large ranges. The goal is not to rebuild like a competitive athlete; it is to build enough surrounding muscle support that affected joints absorb less direct load across normal life, which is the specific mechanism by which resistance training reduces long-term arthritis pain.
Exercises to Avoid With Arthritis
Knowing what not to do is as important as knowing what to do. Several common exercise categories are contraindicated or should be used with extreme caution for people with arthritis.
High-impact activities. Running, jumping, plyometric exercises, jump squats, burpees, and aerobics with significant impact loading generate forces several times body weight at joints. For OA, these forces concentrate directly on damaged cartilage. For RA, they can aggravate inflamed synovium. Running is generally not recommended for established knee or hip OA without specific clearance from a rheumatologist or sports medicine physician.
Deep squats and lunges. Deep squats (below 90° knee flexion) significantly increase patellofemoral and tibiofemoral joint pressure. Deep lunges similarly load the front knee at high degrees of flexion. For knee OA, these movements should be limited to shallow ranges (45–60° maximum) or replaced by the chair-based alternatives described above.
Behind-the-neck exercises. Behind-the-neck lat pulldowns and overhead presses place the shoulder and cervical spine in extreme positions that are poorly tolerated by people with shoulder, neck, or cervical spine arthritis. These movements have few advantages over their in-front-of-neck alternatives and should be eliminated.
Unsupervised heavy free weights. Heavy barbell exercises require significant joint stabilization and can lead to compensatory movements that load arthritic joints abnormally. Without professional coaching, heavy free weights are higher risk for people with arthritis than resistance machines or bands.
Any exercise during an RA flare in the affected joints. This bears repeating: exercising a joint that is actively inflamed in RA can worsen structural damage. Rest the affected joint. Maintain gentle activity in non-affected areas if possible.
A few additional “should-be-rare” categories deserve mention. High-repetition bodyweight moves like jumping jacks, mountain climbers at speed, and plyometric step patterns generate cumulative micro-impact that can irritate knee, hip, or ankle OA even when individual reps feel fine. Long-distance running on road surfaces similarly accumulates compressive load and is rarely the right choice once OA has been imaged. CrossFit-style metabolic circuits that combine fatigue with complex lifts (kipping pull-ups, heavy clean-and-jerks) ask joints to stabilise under fatigue in ways that arthritis makes risky. And yoga flows that include deep forward folds, full lotus, or unsupported shoulder-stand place stress on joints that are often already compromised. Nijs et al. (2015, PMID 26988013) highlight that the central nervous system’s pain-processing system is particularly sensitive in chronic musculoskeletal conditions — meaning painful sessions can sensitise rather than desensitise the pain response. The practical implication: if an exercise consistently produces a pain rating above four out of ten, remove it from the program and replace it with a lower-load alternative that produces similar muscular work.
Managing Flares and Building a Sustainable Routine
For people with RA specifically, the boom-bust dynamic of flares and remissions requires a flexible exercise plan rather than a fixed protocol. During remission: full program, gradual progression. During a flare in a specific joint: rest that joint completely, gentle ROM in unaffected areas, focus on non-impact activities. During a systemic flare (whole-body involvement): rest, consult rheumatologist, restart program cautiously once inflammation has subsided.
For OA, a more consistent program is possible, calibrated to the “acceptable pain” guideline used in physiotherapy research: mild discomfort (under 3/10 on a pain scale) that returns to baseline within 24 hours after exercise is generally acceptable. Pain above 4–5/10, or pain that is worse the following day, signals that load or intensity should be reduced.
EULAR recommendations emphasize that physical activity for arthritis should be individualized, evidence-based, and adjusted to the person’s current health status and joint condition. A physiotherapist or exercise physiologist with arthritis experience can design a program that appropriately manages the trade-offs between loading for adaptation and loading for pain.
According to the ACSM guidelines (PMID 21694556), the target of 150–300 minutes of moderate-intensity aerobic activity per week remains the framework goal even for people with chronic conditions — with the understanding that this accumulates gradually over months, and short bouts (10 minutes) count.
A practical flare protocol for RA: at the first signs of joint heat, swelling, or sharp pain in a specific joint, drop that joint from active training immediately and notify the rheumatologist if symptoms persist beyond forty-eight hours. Maintain gentle ROM in all other joints, keep aerobic work going at reduced intensity if possible (swimming is often tolerated even during moderate flares because buoyancy removes joint compression), and prioritise sleep and anti-inflammatory nutrition during the flare window. Once the flare subsides, reintroduce that joint at roughly fifty percent of pre-flare volume for one to two weeks before ramping back to baseline. For OA, the analogous protocol focuses on acute pain spikes rather than inflammatory flares: if a joint becomes notably more painful over several sessions, cut the offending exercise’s volume by half, reduce range of motion slightly, and review whether footwear, surface, or technique has drifted. Kolasinski et al. (2020) emphasise that OA management is a long-horizon effort — weeks of conservative adjustment beat days of pushing through a painful pattern. The arthritis training plan is more a thermostat than a fixed schedule.
Living Well With Arthritis: Beyond the Workout
Physical activity is the cornerstone, but it works best in context. Body weight management reduces mechanical load on weight-bearing joints for OA. Anti-inflammatory nutrition patterns — emphasizing omega-3 fatty acids, vegetables, and reduced ultra-processed food — may modestly reduce systemic inflammation relevant to RA. Sleep quality affects both pain sensitivity and inflammatory markers. Stress management is relevant because psychological stress can influence inflammatory activity.
None of these are replacements for appropriate medical treatment — disease-modifying drugs for RA, appropriate analgesics for OA — but they are complementary factors that the evidence supports as meaningful contributors to overall function and quality of life.
Three “adjacent” practices also deserve mention because they can change how tolerable the training plan feels week to week. First, heat application before ROM work and cold application after loaded resistance work is an old but effective pattern — the heat loosens stiff tissues and the cold controls any post-exercise inflammatory response. Second, well-chosen footwear makes a larger difference than most people expect for knee and hip OA: shoes with rocker soles or moderate heel-toe drop often reduce knee joint forces during walking compared with flat minimalist shoes. Third, periodic hand or wrist splinting for RA patients during particularly demanding days (travel, extended typing, manual household work) can preserve joint integrity without interfering with scheduled training. Nijs et al. (2015, PMID 26988013) highlight that the whole ecosystem around exercise — sleep, stress, expectations — shapes how the nervous system interprets each session’s signals. Small investments in recovery infrastructure consistently outperform heroic single workouts.
A fourth practice worth folding into weekly life is social movement — group classes adapted for arthritis, supervised hydrotherapy, or walking groups. The behavioural research on adherence consistently shows that social accountability outperforms solitary willpower for long-term compliance with exercise programs in chronic conditions, and Kolasinski et al. (2020, PMID 31908149) specifically recommend supervised exercise formats as part of best-practice OA management when accessible. For home-based readers, asynchronous equivalents — a weekly text check-in with a friend working on similar goals, or a shared session-tracker — capture some of the same benefit.
Begin Your Arthritis-Friendly Practice With RazFit
Starting an arthritis-appropriate program is often less about finding perfect exercises and more about finding a format that fits the unpredictable daily rhythm of the condition. RazFit’s 1–10 minute bodyweight workout library is well suited to this requirement: sessions are short enough to attempt on stiff mornings, the exercise library skews toward joint-friendly bodyweight movements (modified push-ups, chair-assisted squats, glute bridges, bird-dogs, standing rows with no equipment or resistance bands), and the session selection allows users to skip any movement that loads an affected joint without abandoning the day’s training. A workable starting month for a reader with mild-to-moderate knee OA might look like this: week one, three five-minute mobility-and-breathing sessions; week two, add one ten-minute upper-body resistance session; week three, add one aquatic or cycling session of fifteen to twenty minutes; week four, consolidate into a repeatable weekly pattern of three resistance sessions, two aerobic sessions, and daily two-minute ROM blocks. Kolasinski et al. (2020, PMID 31908149) and the EULAR recommendations (Rausch Osthoff et al., 2018) both emphasise that exercise is a cornerstone of long-term arthritis management only when it is sustainable — meaning that small, consistent sessions that survive flare-ups and busy weeks consistently outperform ambitious plans that collapse the first time a joint gets angry. Over three to six months of consistent practice, most users can expect reduced morning stiffness, improved walking tolerance, and a clearer personal map of which exercises work for their joint profile and which need ongoing modification. The arthritis-friendly fitness plan is iterative by design — it grows smarter as the user accumulates weeks of data.

This article is for general educational purposes and does not constitute medical advice. Arthritis is highly variable — type, severity, affected joints, and current inflammatory status all determine what exercise is safe for a given individual. Always consult your rheumatologist, physiotherapist, or general practitioner before starting a new exercise program, especially if you have active RA, recent joint surgery, or significant joint damage identified by imaging. Stop any activity that causes sharp pain, significant swelling, or joint instability, and seek professional evaluation.
RazFit’s bodyweight workout library includes many of the low-impact, joint-friendly exercises described in this guide — from gentle chair-assisted movements to resistance-band alternatives. The app’s 1–10 minute sessions are designed for flexibility and consistency, which is the single most important predictor of long-term improvement in arthritis outcomes.
