Myofascial self-massage with a foam roller on your back is a true classic! With a back roller, you can easily do exercises whenever you have a moment and enjoy some pleasant relaxation—whether after a workout or because your daily routine is taking its toll. Don’t worry: You can even roll the foam roller along your spine. However, if that feels uncomfortable, you’re better off using the BLACKROLL® TWIN—this foam roller spares your spine during foam rolling. The DUOBALL does the same, though its curved design provides a more intense workout for the back muscles. So you have the choice of which foam roller you’d prefer to use for your back exercises.
