Dr. Pat Davidson and Dr. Ben House bring you MASS II.  A 233 page monster of a book that serves as an exercise physiology textbook, a 16-week training program that you could literally run on repeat, and a nutrition and lifestyle manual that teaches you how to be an optimized human.  Here’s what to expect in the words of Pat Davidson:

“MASS was my way of telling the world that I think it’s filled with people who need to be slapped in the face. You think you’ve worked hard? You haven’t done shit. You don’t need a fancy program. You need to try hard. You need to learn how to grind. You need to shut up, stop thinking, and push…day, after day, after day, after day. You think getting punched in the face sucks? It does…but what really sucks is getting punched in the face day, after day, after day, after day. But if you literally just show up today and accept your fate, and you come back again tomorrow, and the next day, believe it or not, you will change…significantly. MASS was a gut check. MASS gave you an acquired taste for shit. Unless you like the way shit tastes, you haven’t really trained. You’ve earned MASS 2. MASS was all about thinning the herd. MASS 2 is about optimization. MASS 2 will make you have video game numbers in your lifts.”

    Awesome program and I like how it addresses more of the variables that can effect your training. I did not see the hyperlink for the video on how to use the spreadsheet however

      Hey Patrick,
      Sorry about that man. Feel free to shoot me an email at and we can get the spreadsheet piece squared away.
