Q: What are foam rollers used for?
A: A foam roller—a cylinder-shaped log of hard foam—is used like a rolling pin to stretch your tendons, and is a great way to warm up for activity. I find this tool especially good for loosening up hard-to-stretch tissue like the IT (iliotibial) band, which runs down the side of your leg from your hip to your knee. You lie on the roller and pull your body slowly back and forth across the roller. It might be a little uncomfortable while you are doing it, but it feels unbelievably good when you’re done. —Orthopedic surgeon Dr. Vonda Wright, Author of Fitness After 40
