Aerobic Exercise
In Fibromyalgia, Relief through gentle movement Stacie Bigelow writes, “Aerobic exercise is the closest thing to a medical magic bullet that has ever been found.”
Aerobic exercise is any continuous, rhythmic activity that raises your heart rate and makes you breathe a little more deeply. Walking, cycling, swimming, water exercise and gentle dancing are all examples.
Regular aerobic exercise can improve circulation, cardiovascular fitness, stamina, mood and the body’s ability to regulate blood sugar. For people with fibromyalgia, it may also gradually reduce pain and stiffness and make everyday activities feel less demanding.
The difficulty is getting started.
Exercise Does Not Have to Hurt
Exercise places a temporary demand on the muscles, joints, heart and nervous system. If an activity is unfamiliar, you may experience some soreness afterwards. However, exercise does not have to hurt to be beneficial.
People with fibromyalgia may experience a stronger response than other people to the same amount of activity. An exercise session that feels manageable at the time may be followed by increased soreness, stiffness or fatigue later that day or the following morning.
When you are already stiff and sore, the natural response is to avoid doing anything that might make you feel worse. This can create a difficult cycle:
Pain discourages movement. Less movement reduces fitness and tolerance. Ordinary activities then require more effort and may produce even more discomfort.
The way out of this cycle is not to push harder. It is to begin with an amount of exercise your body can tolerate and increase it slowly enough that your body has time to adapt.
Choose the Right Goal
High-intensity training is often used by athletes who are trying to improve speed or performance. That is not our immediate goal.
For someone with fibromyalgia, the first goal is to establish a comfortable and repeatable pattern of movement. Consistency is more important than intensity.
Begin with very light exercise for a short period. As your tolerance improves, gradually increase the duration before increasing the speed or difficulty.
The best exercise is not necessarily the one that burns the most calories or produces the greatest fitness gains on paper. It is the one you can perform regularly without repeatedly provoking a flare-up.
How Hard Should It Feel?
During gentle aerobic exercise, your breathing should become slightly deeper and faster, but you should still be able to speak in complete sentences. This is sometimes called the talk test.
You should feel that you are exercising, but not struggling. If you are gasping for breath, unable to speak comfortably or becoming increasingly tense, reduce your pace.
Heart-rate formulas can be useful, but the talk test is often more practical because fibromyalgia symptoms, medications, temperature and sleep can all affect how exercise feels from one day to the next.
Begin With Five or Ten Minutes
You do not have to complete a conventional 30-minute workout.
Some people may need to begin with only five minutes of walking, gentle cycling or movement in water. If that is too much, begin with two or three minutes. Short periods performed at different times of the day still count.
Once you can repeat that amount without a significant increase in symptoms, add a minute or two. Remain at the new level until it feels familiar before increasing it again.
Change only one thing at a time:
-
Duration
-
Frequency
-
Speed
-
Resistance
-
Terrain
Increasing several of these together makes it difficult to know what caused a flare-up.
Low-Impact Choices
Begin with activities that place relatively little impact on the joints and muscles:
-
Walking on level ground
-
A stationary or recumbent bicycle
-
Swimming
-
Walking or exercising in warm water
-
A gentle step machine
-
Low-impact dancing
-
Seated aerobic movement
High-impact activities involve jumping and landing with substantially more force than walking. Jogging, skipping and jumping jacks are common examples. These activities are not necessarily forbidden forever, but they are usually poor starting choices for someone who is already experiencing widespread pain.
Water exercise can be especially helpful because the water supports the body and reduces loading on painful joints. However, water temperature and the effort required to change clothes, travel and shower should also be considered. The complete cost of an activity matters—not only the exercise itself.
Work Around Sensitive Areas
Do not repeatedly force a painful area through an exercise that clearly aggravates it. If your neck is particularly sore, for example, choose an activity that allows your head and shoulders to remain relaxed.
This does not mean that a painful area should never be moved.
Complete avoidance can contribute to further stiffness and loss of function. Modify the movement, reduce its range or choose a supported position until you can use the area more comfortably.
Sharp, localised or unfamiliar pain is different from ordinary muscular effort and should not be pushed through.
Warm Up and Cool Down
Never begin or end exercise abruptly.
Start with several minutes of slower, smaller movements. This allows your breathing, circulation and joints to adjust. At the end, gradually reduce your pace rather than stopping suddenly.
A warm-up and cool-down do not need to be elaborate. If your chosen exercise is walking, simply walk more slowly at the beginning and end.
What to Do During a Flare-Up
Fibromyalgia symptoms naturally fluctuate. A difficult day does not mean that your entire exercise program has failed.
During a flare-up, you may need to:
-
Reduce the pace
-
Shorten the session
-
Divide the activity into smaller periods
-
Choose water-based or seated exercise
-
Replace formal exercise with gentle everyday movement
-
Try to maintain the habit at a level your body can tolerate. However, rest and seek appropriate medical advice if symptoms suggest an injury or illness rather than a familiar fibromyalgia fluctuation.
Learn From the Following Day
The true measure of an exercise session is not only how you feel while doing it, but also how you feel afterwards.
Keep a simple record of:
-
What activity you performed
-
How long you did it
-
How difficult it felt
-
How you felt later that day
-
How you felt the following morning
If symptoms become substantially worse, reduce the next session. If your symptoms remain reasonably stable, repeat the same amount before considering a small increase.
Progress is rarely a perfectly straight line. What matters is the overall direction across several weeks, not the occasional difficult day.
Key Points to Remember
-
Start with a very small, manageable amount.
-
Choose low-impact exercise initially.
-
Increase duration before intensity.
-
Change only one part of the program at a time.
-
Use the talk test to control your pace.
-
Warm up and cool down gradually.
-
Modify exercises around sensitive areas.
-
Do not use pain as a measure of success.
-
Reduce the dose during a flare-up rather than regarding it as failure.
-
Choose activities you enjoy and can realistically continue.
The aim is not to prove how much exercise you can endure. It is to help your body become more capable, one manageable step at a time.
