The Scorcher is a high burn full body workout that alternates the load from the muscles to the lungs and back again. Obviously all muscle activity requires good VO2 Max performance but larger muscle groups need more oxygen to function while smaller ones help maintain that familiar recover-on-the-fly feeling that comes with high-burn exercises. Add EC for that extra edge and you have more than earned your food this day.
Extra Credit: 30 seconds rest between sets.
