Product descriptionSize: 8*16cmColour: BlackMaterial: EPPPackage content: 1*Peanut massage ball1.Perfect Design For Comprehensive Massage This split peanut-shaped massage ball is a perfect design to get to those hard to reach stabilizing muscles that surround your spine and vertebrae without applying pressure on them as you lay on it.2.Durable Material The massage ball is made of EPP rubber, which is firmer than tennis ball, but not like the hard plastic balls with knobs and they hurt. It is durable for long-lasting use.3.RELAXING AND PAIN RELIEF Fascia training is the ideal addition to traditional treatment methods such as classic physiotherapy, osteopathy and connective tissue massage. In this way, muscle tension and adhesions in the fascia tissue are specifically released through self-massage.4.ERGONOMIC The ball can be used universally. Due to the depression in the middle, the ball is particularly suitable for neck and back exercises along the spine, in which the muscle tissue can be optimally massaged in contrast to a fascia roll.5. PERFORMANCE ENHANCINGTop athletes perform fascia training after a hard workout in order to increase the ability of the muscles to regenerate. The deep tissue massage leads to a significantly improved supply of the tissue and prevents muscle soreness. This means that you can train earlier again and make greater progress.
