Think about your favorite pair of jeans, fresh out of the dryer, certified personal trainer Jessica Smith says in the Shape.com video above. A little too stiff for you to, say, squat all the way to the floor?
Cold muscles are kind of like those stiff jeans, she says: If they're not loosened up, you won't be able to perform a full range of motion through some of your favorite exercise moves. Enter the foam roller. This tool is well-known for relieving stiffness and increasing mobility, which can in turn enhance performance in your next workout.
