Pressure from Aku Ball and Aku Mat’s metal spikes against skin is believed to trigger a healing response in the body that feels warm and revitalizing and can stimulate circulation to enhance physical and mental performance.
The metal spikes are a traditional—and deliberate—touch. The metals are ones found in the body, like silver, zinc, and iron. Fitting in a squeeze or roll with the Aku Ball is easy and you can do it when you’re just about anywhere. Aku Mat has a higher-intensity level, but it’s the same idea: lay, roll, or stand on the metal spikes. It looks intimidating, but those of us who tried it enjoyed it. And you can do it for as long as it feels comfortable and build up your practice over time.
