ZenKahuna (Rocannon MacGregor) is very active on YouTube. His videos often demonstrate mindful movements that one can do with clubs, maces, kettlebells and more. One of the implements ZenKahuna has come up with is called the Double Ball Staff which he says can help with brain organization and training, mobility, strengthening joints & sinews, digital dexterity, and enhancing fluid moving skills. These are made in Idaho by Rosewater Kinetics.
