The small sustainable helper made from Black Forest wood for targeted and isolated treatment of tissue structures. Ideal for the targeted treatment of the back extensor and the soles of the feet, as well as for specifically rolling out the calf and forearm muscles. It provides a pleasant and warm feeling on the skin thanks to the natural wood product. 100% natural and completely biodegradable. Handmade in Germany from FSC-certified wood. The double ball is the perfect companion for the targeted treatment of chronic tensions or the loosening of "tight" connective tissue structures. This small helper is particularly suitable for muscular tensions in the area of the thoracic and lumbar spine, as well as for the entire back area. The innovative groove spares the spine, allowing for optimal pressure distribution. The initial feeling of pressure during application soon gives way to a pleasant sensation of relaxation. Tensed back muscles will soon be a thing of the past. The rolling wood double ball can also be used preventively and for regeneration. For example, stressed connective tissue structures along the Achilles tendon after a jogging session can benefit from a small rolling session. This promotes recovery and can specifically counteract emerging complaints. Instructions and inspirations for use can be found in the e-book for fascia training (included with the purchase of the product) as well as on the website or YouTube channel.
