Bests & Worsts Reviews from Amazon

When you understand the physics of the problem this product makes more sense. The way you get that deep tissue is by increasing the pressure. Specifically I’m referring to pounds per square inch. Given that gravity is constant the only way to do this is to distribute the same amount of weight across a smaller area. So you get the intensity of a deep stretch throughout your erectors. The downside is because it smaller to increase the pounds per square inch it makes it harder to balance on compared to a traditional foam roller. But a traditional foam roller will never dig in this well. If you’ve got decent balance ability give it a try. If your ability to balance is compromised this might not be for you.
