The Active Ball is designed with reliability and ease of use in mind. This is a vibrating ball that can be quickly charged to help relax muscles and fascia through high-intensity vibration. It is easy to carry thanks to its compact size and delivers three different types of vibration. You press the power button lightly to check the battery charge level and strongly to change the vibration level. This split peanut shape is a perfect design to reach those harder to reach the muscles that surround the spine and vertebrae without applying too much pressure.
