If you’re a fan of The Walking Dead like me and watched last Sunday’s episode then you saw a fantastic demonstration of the skills necessary to survive the zombie apocalypse.  One of the key skills that stood out more than any other was physical fitness. Now when I say physical fitness I’m not talking about how diesel you are— when you get swarmed by the herd it is unlikely that your 300 lbs bench press or your 500 lbs dead lift will come to your rescue—or how flexible you are—it is just as unlikely that your Parivrtti Trikonasana to Prasarita Uttanasana yoga pose will allow you to twist and flip through the herd like you’re Eddie Gordo from Tekken 3.  No when I say physical fitness I am talking about the often hated and often overlooked component in everybody’s program—Cardiorespiratory Endurance.
