The Aku Roller is a dynamic massage tool designed to relax tense muscles, improve circulation and stimulate healing. Experience the power of 570 acupressure spikes working to release tension and knots from your muscles in seconds. The Aku Mat is based on the principles of acupressure and reflexology and works on the premise that tiny metal spikes stimulate active nerve centers to increase blood flow and lymph circulation. This reflective action reduces inflammation while triggering the release of endorphins. Endorphins are known as the feel-good neurotransmitters of the body and are an essential part of the body's natural healing process. When released, endorphins interact with receptors to reduce pain, anxiety and stress while providing a sense of calm, relaxed, euphoric pleasure.
