The episode is chock full of information and the author made sure that it can also be applied in real life. He must have been really selective in picking from the most basic work-out to the hardest and also made sure to explain things properly to avoid injury. I wish they could have explained more about protein but I'm guessing it would take too long to explain it. P.S. There is a cameo in this episode proving that this world is in the same kenganverse.
