Thera Roll Thera Stick. Sweet relief from sore, aching muscles is only a Thera Roll Thera stick session away. Outside of visiting a massage therapist, using this foam roller is the best means to recover from the rigors that riding places on your muscles and tendons throughout the body. And with the Thera Stick, the foam roller session is self administered so you can take care of yourself wherever you are and whenever necessary. The Thera Stick's patented textured ribbed ridged design mobilizes soft tissue to enables deeper access to muscles so you can more precisely target sore and knotted tissue. And when compared to traditional smooth rollers, the Thera stick's ridgedribbed design prevents excess sliding so you have more control of the roller position to achieve effective tissue release. Two different densities are on offer Purple firm and Grey hard with the Grey roller the firmer of the two options. While both options deliver a deep release of sore and tired muscles, the Purple is intended for fitness enthusiasts while the Grey was designed with competitive athletes in mind. The Thera Stick is perfectly portable and can travel with you to ensure a massage session is readily available at your convenience.
