The Knotty Tiger Jr. is a massage roller ball for everybody to help relieve minor muscle knots, aches, and soreness. This little knot-buster eases stiffness as well. Able to roll on your clothes and skin, it saves your hands and fingers from fatigue. This tool simulates the deep tissue elbow massage technique of a therapist. With the right amount of pressure, it feels like someone is using their elbow to help dig into tough, tight muscles. Ideal for those who carry stress and tension in the back and shoulders. Works best for self-massaging on the neck, shoulder, pecs, biceps, triceps, arm, hip, IT band and other small muscles. Suitable for multi-user environments as well as personal home use. The Knotty Tiger Jr. is a recommended Trigger Point Release Tool (TRP Release Tool) by Physical Therapists, Chiropractors and Athletic Trainers. Its patented non-slip grip ensures secure, controlled muscle manipulation. When you add essential oils to this tool, you turn your massage into an aromatherapy session. Easy to use and easy to clean. Simply use anti-bacterial gel or gently wash the surface with soap and water. At less than 3? tall and weighing less than a pound, the Knotty Tiger Jr. is small and portable, making storage and snap and travel a breeze.
