Foam rolling is essential for anyone who frequently does cardio exercise. This foam roller by PharMeDoc is probably the best I've ever owned. It's small enough to stash in my back seat or under the coffee table, and it has just enough cushioning to not cause pain when rolling tight muscles. Its unique padded texture is great for rolling out and massaging sore back muscles; in fact, this roller really helped me recover from a lingering bout of lower back pain. This is a great buy whether you're into biking, running or walking, or even if you just want to maintain flexibility.
