You may think of your foam roller as just a tool to help soothe your achey muscles, but it's actually a great piece of equipment to add to your core workouts as well. Adding an unstable surface, such as a foam roller increases the demand on the core stabilizers. These muscles help to support your posture and protect your spine. These exercises will put you on the fast track to building a solid foundation.
Be sure to check with your health care professional before you try these, especially if you've had an injury.
