Piriformis syndrome is a frustrating condition that's literally a pain in the butt for runners. This throbbing ache originates in the buttocks and often radiates down the legs and/or to the spine. The culprit is an overtaxed piriformis muscle (from running on uneven ground or having tight hamstrings, for example) that spasms and aggravates the sciatic nerve. (Search: Is piriformis syndrome normal, and how long does it last?) This routine will help keep your piriformis strong and flexible. Do the exercises three times each week, after a run.

After a long run or intense workout, end your stretching session by placing a tennis ball under your right sit bone. Put all of your weight on the ball and slowly rotate your hips to release the piriformis. Do this for several seconds, and then switch sides.
