I am an endurance athlete that often has sore muscles and joints after a long week of cycling and running. This bundle gives all the options you would need for faster recovery to be able to get back at it. I always start with the Axle because it can hit those large muscle groups (quads, hamstrings, calves) that usually need the most work for me after a long run. Unlike traditional foam rollers, the Axle feels firm and not squishy while also being anatomically designed to work well on my back muscles. All the options in this package feel very well made and built to last unlike some other recovery tools that I have tried.
