Sometimes your gym floor isn’t so inviting to be to do some myofascial massage (foam rolling), without discomfort. That’s why we decided to make a roller that can be mounted to your Kingsbox Mighty structure.It is attached with only one removable pin to the Rig/Rack, which means you can mount it on any height and therefore quickly adjust it to the right height to massage your neck, shoulder, spine, or thigh muscles. It is great for places that are difficult to reach with a lacrosse ball and other mobility aids.
