Myth 1: 'Exercise Wears Joints Out'
Cartilage is living tissue and depends on movement for nutrition — joint fluid is squeezed in and out like a sponge with every step. Decades of research, including long-term running studies, show that regular low-impact exercise does not cause or worsen osteoarthritis. It is inactivity, not activity, that accelerates joint degeneration.
Myth 2: 'Rest is Best During a Flare'
Brief rest for 24-48 hours during an acute flare is sensible, but complete bed rest is harmful. Muscles weaken within days, joints stiffen, mood drops and pain sensitivity rises. Gentle range-of-motion exercise even during a flare preserves function. Our flare management guide shows what to do day-by-day.
Myth 3: 'No Pain, No Gain'
In arthritis the opposite applies. Mild discomfort during exercise that settles within an hour is acceptable; sharp pain or pain still worse 24 hours later means the dose was too high. The right exercise intensity makes you breathe a little harder but does not flare you the next day.
Myth 4: 'Painkillers Before Exercise Are a Cheat'
For some people, a planned dose of paracetamol or a topical NSAID 30 minutes before activity is the difference between exercising and not exercising. Discuss with your GP, but using analgesia strategically to enable movement is good practice, not weakness.
Myth 5: 'Strength Training Is Dangerous'
Progressive resistance training is one of the strongest evidence-based treatments for knee and hip OA, reducing pain by 30-50% in trials. Start with bodyweight or light bands, two to three sessions per week, and progress gradually. Strong quadriceps absorb load that would otherwise hit the knee joint.
Myth 6: 'I'm Too Old / Too Stiff to Start'
Studies in people over 80 with severe OA show meaningful gains in strength, balance and pain within 8-12 weeks. It is never too late. Begin with chair-based exercise, pool work or 5-minute walks and build slowly.
What the Evidence Actually Recommends
150 minutes of moderate aerobic activity per week, two strength sessions and daily flexibility work — the same prescription as for the general population, adapted to your joints. Our best exercises for arthritis guide gives a starter plan for every joint.
