Do housework—and make it fun. Turn on music while you vacuum or clean so you move a bit quicker while you work. "Whatever activity you're doing, think of a way to make it a little bit more taxing than it would be otherwise," advises Fontaine.
Finally, if you'd like to step up your routine a bit but don't feel ready for joint-pounding exercise, consider water or aqua exercise. Warm water can be especially therapeutic, Fontaine says. A 2008 study published in Archives of Physical Medicine and Rehabilitation found that exercise in a warm pool three times a week for 16 weeks improved many fibromyalgia symptoms in a group of previously unfit women.
