Inferno is a Level 4 High Intensity Interval Training (HIIT) that places quite the load on the entire body and keeps it there for the duration of the workout. Make sure High Knees are performed by bringing the knee to the height of the waist and keep your body straight and your arms pumping while you are doing it. This is a high-burn, lots-of-sweat kind fo workout so be prepared to feel its effects.
Extra Credit: Hit the same number of burpees in 20 seconds every time.
