The BLACKROLL DUOBALL is particularly effective for massaging and releasing tensions in parallel lines of muscles, e.g. along the thoracic and lumbar spine - the areas where we feel upper and lower back pain. It can also be used to target the upper thighs, tight hips, calves and the areas around the Achilles tendon.
We recommend the DUOBALL 12cm for taller people with wider backs and is really effective for treatment in the slightly wider lower back area. The DUOBALL 8cm would suit smaller people and suits in between the shoulder blades and neck regions.
