A fast, energetic, cardio-pumping workout helps work up a good sweat, get your body moving and burn up some calories. The Big Bang workout does all of that but in addition its switch from speed to strength also challenges the muscle control you have over your body. This is perfect when you want to exercise but are not sure what you want to do but still do not want to feel cheated out of a good work out.
Extra Credit: 30 seconds rest between sets.
