Warlord is a slow, deceptively easy looking workout that loads a lot of different muscle groups and does not let up. This is a power-building workout that will make you feel the heat around the 4th set or thereabouts. Go deep in your lunges, make your jabs and hooks form-perfect by swiveling on the ball of the foot that's on the same side with the arm you are punching with (so that your body's weight goes behind the punch) and keep your body absolutely straight in the planks. You will soon feel just what muscle groups you are conditioning.
Extra Credit: 1 minute rest between sets.
