To truly harness your body's power you need strong glutes, quads and calves. Unparalleled fascial fitness. Good lungs that can maximize the oxygen extracted from each breath, hence good VO2 Max and a strong heart to pump oxygenated blood where it's needed and get rid of the build up of CO2 in the bloodstream; hence a good cardiovascular system. Power Boost is a workout that will take you to the very edge of your ability. It will also boost the confidence you have in the raw ability of your own body. Add EC and there may just be a tear or two mixing in with the sweat.
Extra Credit: No rest between exercises.
