"The Best Workout Recovery Tools To Relieve Muscle Soreness And Improve Mobility"

The R4 was designed to relax the spine and neck while rolling the back muscles. The center groove can also single out the IT-Band and Achilles tendon.


The surface pattern and proprietary EVA foam were carefully considered to provide the best feel and friction.
Unlike any other foam roller on the market. Designed to reach the areas you need it most, including the neck muscles.


Thoughtfully designed for you. Take a moment out of your day to work out the tight spots.
Used by World Champions, Olympic Champions and professional athletes.

Why we made it
We wanted to create something really special with the R4. To make the best of something requires a great deal of thought and questioning. How do we make it durable for years of use? How can we target so many different muscle groups? What kind of density is just right? Why are so many foam rollers out there so ugly? Does it really need to vibrate or is that a gimmick? How do we make it joyful to use? These are the questions that we believe we've answered with the creation of the R4. It is our hope many athletes will find it useful in their recovery arsenal.

Impressive
"I love the groves on the R4 for my back. It's the best foam roller I've used."
