If you're attempting to balance your metabolic energy systems, burning a few hundred extra calories after throwing around some serious weight has its advantages.
But for the vast majority of people, that extra few minutes spent pounding away on a cardio machine floods your body with inflammatory hormones, kills your body's natural anabolic response to training, and sets you up for a long, hunger-filled afternoon.

At this point you may be asking yourself, "How the hell am I supposed to get my heart rate up while staying relatively lean and strong without killing myself, killing my muscle tissue, or just killing my body composition as a whole?"
The answer is Six Pack finishers.
