ng hours in the saddle and hard workouts can leave your muscles riddled with knots and scar tissue created as they repair themselves. And because all your muscles are connected, those sore spots can spread throughout your body if not treated—a tight lower back creates an achy hip that leads to a twinged knee. That's why so many cyclists swear by massages. They help loosen tight spots, flush toxic chemicals, and keep your fibers smooth and limber so you can ride pain free.
