Convict Conditioning or the Naked Warrior?

Hi everyone, I am trying to decide on if i should buy Convict Conditioning or Naked Warrior? I can not buy both right now. My goals are to increase my strength and reps incredibly! I am on my JROTC physical training team and we have 3 competitions this year. I am already almost qualified to go to the one at the beginning of September. The next two i want to be overly qualified haha. I am also preparing to join the military next summer. Which book is the better choice for this? I am also beginning the Warrior Diet
