Quite hollow - but only to spare your spine
The BLACKROLL® TWIN is a combination of the classic BLACKROLL STANDARD FOAM ROLLER and the DUO BALL 12. The recess in the middle makes the BLACKROLL® TWIN suitable for treatment of the back, as the spinal column is not affected during rolling. The contact surface of the BLACKROLL® TWIN is slightly wider than the BLACKROLL® DUOBALL. This makes the fascial massage of the back more extensive and less punctual. Furthermore, the bar in the center ensures that the skin and tissue are further stimulated (especially in the legs and arms).
- Flat and selective self-massage with skin stimulation
- Ideal for treating the spine, calves and parallel trigger points
- Stimulation & increased blood circulation of the tissue by twisting in the middle
- Average hardness level
- Recyclable and durable material with a high quality surface
