The TriggerPoint GRID X Ball is an extra-firm 5-inch massage ball with the GRID pattern technology for a deep tissue massage. With a firmer surface than the original GRID Massage Ball, the GRID X Massage Ball can withstand more pressure and help relieve sore muscles.
The 5-inch diameter and firmer density helps target muscles in hard to reach places such as shoulders, traps, and hips. Its lightweight and portable size is convenient to travel with you or bring to the gym so you can roll out anywhere.
The GRID X Ball is approximately 5 inches x 5.7 inches x 6.4 inches
