The Sport-Thieme Fascia Trainer Bumps relieve muscle tension. Made from high-quality materials, the Sport-Thieme Fascia Trainer Bumps impress with their stability and durability. The fascia trainers are available in both small and large sizes. The small massage roller is ideal for treating arms and legs, while the large roller is perfect for extensive self-massage of the back.
