RAD Rod Massage Tool - Fully loaded with a steel core and soft outer shell that stick it to tension. The slender design minimizes surface area so you can fine-tune your pressure without pain—even on bony areas like the shins. That means tight muscles and built-up toxins better watch their backs because this rod rocks concentrated release and maximum relief the way only RAD can. The RAD Rod is a thin, portable myofascial release tool that lets you customize your level of pressure to a tee. This roller leaves the competition in the dust with its thoughtful engineering, high-quality materials and steel-core control.
