The MB1 Massage Ball is a great choice for targeted relief. It’s EVA foam surface more effectively “grips” the areas being addressed to release discomfort and tightness without pinching or irritating nerves like a harder golf ball or lacrosse ball might do. With a slip resistant texture, the MB1 can be used on any hard surface, so you can roll anytime, anywhere. For best results, place the ball directly on the area of discomfort, apply pressure and roll side to side.
