Day One- workout complete

I have decided that I am going to do the Doubles workout. It will be super intense but I am athletic, just an out of shape athlete and I can do this. SO, I did Chest and back and the ab ripper x. I did every workout but I just couldn't get through the whole time for each set. Pull ups and Chin ups are very hard for me but I know that if I push myself to the fullest, I can get them done.
