Exercise can reduce pain and improve function in people with
rheumatoid arthritis (RA). In addition, exercise may
help prevent the buildup of scar tissue, which can lead to weakness and
stiffness.1 Exercise for arthritis takes three forms:
stretching, strengthening, and conditioning.
Stretching involves moving joint and muscle
groups through and slightly beyond their normal range of motion and holding
them in position for 10 to 30 seconds. See illustrations of various
stretches
.
Strengthening involves moving muscles against
some resistance. Studies have shown that moderate- or high-intensity strength
training is well-tolerated in people with rheumatoid arthritis and can help
increase or maintain muscle strength.1 In addition,
another study reports that a program of long-term, high-intensity
weight-bearing exercises improves the functional ability, physical capacity,
and emotional status of people with rheumatoid arthritis.2 There are two types of strengthening exercises.
- Isometric strengthening is
simply tightening a muscle or holding it against the resistance of gravity or
an immovable object without moving the joint. For example:
- Tighten the front thigh muscle of the leg or
lift the leg 2 in. (5.1 cm) off
the floor while seated.
- Push the wrist against the undersurface of
a table.
- Isotonic strengthening means
moving a joint through its range of motion against the resistance of a weight
or gravity. For example:
- Put a
3 lb (1.4 kg) weight on your
ankle and then bend and straighten your knee.
- Lift free
weights.

Conditioning exercise improves aerobic
fitness. Conditioning, or aerobic, exercises include
walking, biking, swimming, or
water
exercise. A target heart rate can guide you to how hard you should
exercise so you can get the most aerobic benefit from your workout.

Target heart rate is only a guide. Each individual is different, so
pay attention to how you feel while exercising.
Note that even moderate activity, such as walking, can improve your
health and may prevent disability from rheumatoid arthritis.
Be sure to follow your health professional's advice about your
exercise program. For most people, physical activity does not pose any problem
or hazard. For some people, some forms of physical activity might be unsafe or
should be started only after talking with a health professional. See a list of
exercise cautions to consider before beginning any
exercise or fitness program.
