DO IT YOURSELF

If your gym has a punch bag this is easily replicated – minus the awesome atmosphere, of course. Do 3 x 2-minute rounds of drilling combinations, mixing up straight punches, hooks and uppercuts. Alternate between speed and power. Then switch to 3 x 2-minute rounds of plank holds, press-ups and lunges, taking little rests in-between. Repeat the entire thing two or three times in total.
