Every serious bodybuilder knows the awesome feeling of training in the zone. Banging off reps with a serious stack of plates on the bar, your muscles burning with a pump so intense you swear your skin is going to rip. Yeah, being in the zone is a big time thrill, and for sure helps you build freakish muscle. But, the zone is nothing without the "X". The zone is how you train. The "X-Factor" is how you grow!

...up to 15 lbs of muscle after just one 50 day cycle!
