RAD HELIX is created to adapt to the shape of the human anatomy. The double cone allows release in two planes, tension and open the column while the grooves allow you to create pressure waves that push waste materials away from your muscles. The large groove in the center allows it to roll on the erectors of the spine without putting pressure on the spinous processes.
Helix is composed of a polymer specifically created to be soft enough to roll over all the muscles but strong enough for hard work. This polymer is waterproof and non-porous and does not become smelly and slippery like the typical foam roller.
Roller and Helix
Both can be useful in the back but respond to two different and distinct functions.
