The RAD Rod is fully loaded with a steel core and soft outer shell that stick it to tension like nobody's business. 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. On-demand release is the name of the game for the RAD Rod. It's stainless steel core offers no-nonsense control at every level of intensity you could ask for. Use after use, the RAD Rod reigns supreme over flimsy, flexible stick alternatives because it doesn't bend, break or give in when you give it your all. This sturdy build empowers you to dominate areas with thick tissue (think hamstrings and quads), or you can lighten up and use it on the usual suspects, like your calves, back and IT bands. Just try it and you'll see: inflexible steel equals more intense muscle-flushing action, which is why the RAD Rod is just a real straight soother. Pair with the RAD Helix to increase versatility.
