Exercising With Joint Pain or a Larger Body

The short version

For most people with arthritis or joint pain, movement helps. It can reduce pain over time.
Water exercise, cycling, walking and chair-based workouts are gentle on the joints.
Mild, short-lived discomfort is usually fine. Sharp pain, or pain that lasts for more than a couple of hours, is a sign to back off.
You don't have to lose weight before you can exercise, and you deserve to feel comfortable doing it.

Does exercise make joint pain worse?

For most people with osteoarthritis, regular activity reduces pain and improves function over time. Muscles around a joint help protect it, and stiff joints tend to become stiffer without movement. Losing even a little weight helps as well. One study found that each pound lost took about 4 pounds of force off the knee with every step.

It can feel a bit worse before it feels better, which is why starting small matters.

Gentle options

Water walking or water aerobics. The water supports your weight. It's the top option for very sore joints, and if you can't swim, you don't need to.
Stationary or recumbent cycling. Easy on your knees and hips, and a recumbent bike supports your back. Set the seat so your knee is slightly bent at the bottom.
Walking. Choose flat, even surfaces and supportive shoes. Use poles or a cane if it helps you. Short walks spread through the day are often more comfortable.
Chair exercises. A real workout that doesn't require standing. See level 1 here.
Tai chi and gentle yoga. These are good for balance, flexibility and confidence.
Strength training with machines or bands. These let you control the range of motion easily.

The pain rule

Use this as a rough guide, unless your clinician has told you otherwise:

Mild ache during exercise that settles within about 2 hours: Usually fine.
Pain that lasts more than 2 hours, or is worse the next day: You did too much. Reduce next time, but don't stop altogether.
Sharp, sudden pain, a joint that gives way, or swelling and heat: Stop and get it checked.

Practical tips for larger bodies

These are the things people often wish someone had told them:

Chafing. Anti-chafing balm and moisture-wicking shorts help a lot.
Support. A properly fitted sports bra and supportive shoes make a surprising difference.
Equipment limits. Check the weight rating on bikes, benches and treadmills. Many are rated for 300 pounds or more, and some go higher.
Floor work. If getting up and down is hard, use a chair or a raised bench, or do exercises standing or on the bed.
Heart rate and breathlessness. It's normal to feel out of breath early on. Slow down, rest, and go again. Fitness can improve quickly.
Gyms. If you're worried about feeling judged, try quiet hours, a beginner class, a community pool, or home workouts. You have every right to be there.

How to start

Pick one activity. Do 5 to 10 minutes, every other day, for two weeks.
Add 2 or 3 minutes per session each week, as long as your pain rule is okay.
Warm up with gentle movement. Heat can help stiff joints beforehand, and ice can help with any flare-ups afterward.
Add 2 days a week of gentle strength work after a few weeks.
