The range comprises single balls (BALL 08 & BALL 12) as well as double balls (DUOBALL 08 & DUOBALL 12). What’s the difference here?
The BALL 12 is a fascia ball in large with 12 cm diameter. It is the ideal fascia ball for larger muscle groups, such as thighs or calves. The BLACKROLL® BALL 12 is also available as a small fascia ball measuring 8 cm in diameter. This is particularly ideal for relieving individual muscle tightness, encouraging blood circulation in the tissue and reducing pain. Since the surface area of the small fascia ball (BALL 08) is smaller, it is more intensive to use.
BLACKROLL® DUOBALL: The BLACKROLL ball for the back
If you're looking for a fascia ball for the back, the DUOBALL double ball is the perfect tool for you. Whether the DUOBALL 12 with a 12 cm diameter or DUOBALL 08 with an 8 cm diameter, this fascia ball effectively treats parallel muscle areas by opening the bony projection. The same applies here too: the small double ball (DUOBALL 08) is more intensive to use.
