The GRID Ball is a medium-size massage ball that features TriggerPoint's patented GRID surface pattern that replicates the feeling of a massage therapist's hands, yielding a unique and versatile self-massage tool. It's crafted from a premium, medium-density EVA foam that provides a moderate level of pressure. Its surface is water-resistant and sweat-resistant, making it easy to clean, while its smooth foam composition rolls comfortably against skin. Our patented GRID pattern replicates a massage therapist's hands in three unique configurations: flat areas like the palm for addressing large muscles, tubular ridges that knead muscles like the fingers, and dense nodules for applying targeted pressure like fingertips. This gives you an incredible amount of versatility to customize how the GRID Ball interacts with your body, so you can hone your self-massage experience to target sore muscles with the precise sensations and pressure you need.
The GRID Ball is a nice middle ground between a smooth foam ball and something painfully hard. The three surface zones really do feel different: flat areas are good for larger muscles, the ridges knead, and the nodules get into tight spots. Medium-density EVA foam gives moderate pressure, which suits me for shoulders and glutes without wincing. The surface wipes clean easily and rolls smoothly on skin. It's small enough to toss in a gym bag, and it's become my go-to for quick self-massage after workouts.
