When time changed for the land of the rising sun and the noble samurai were no longer quite needed, the Ronin, masterless Samurai, appeared everywhere. Swords for hire with a moral code, they're responsible for some of the tales of heroism, we have from that time. This is the time of Miyamoto Musashi, the fabled 'Sword Saint' and author of Rin-Go-Sho (The Book of Five Rings), hailed as the ultimate treatise on combat. The Ronin workout is a direct thread connecting you to that time. You feel your spirit resonate, your body thrum and as you get to the first lunge cut you know, deep inside, that yours too is a Warrior Code.
