Ninja are the fabled mist warriors, appearing and disappearing almost like magic, displaying practically superhuman powers. But they have to train too. Ninja warriors can do a lot of fancy moves but they rely on core strength in order to do so. The Ninja Warrior workout targets the muscles you need in armed and unarmed combat to help you develop the kind of strength that allows you to move your body with confidence.
Extra Credit: 30 seconds rest between sets.
