1 This massage tool has an ergonomic two-ball design that helps distribute pressure to specific trigger points. Great for massage therapy of different muscle groups such as the foot, neck, leg, hip, and thigh.

2 It is quite similar to a sports ball which also offers soft support and relief, but this is more lightweight and can be brought along for travel.

3 The curved ball shape conforms to the shape of your vertebrae and carefully cradles the spine. 

4 This also makes it ideal for lumbar support and massage therapy.
