I really like this. In that spirit, my “craziest” good idea was probably running CT’s programs back-to-back for a stretch: look like a bodybuilder, I, BB, and 6 weeks to superhero. That was crazy because that’s simply not how lifting was done! I learned a ton and really was able to branch out.
Craziest diet, definitely good idea, was the velocity diet. It looked like a slim-fast commercial on first glance (which I’ve also done), but I got a lot out of it and think of protein as more than just a minimum amount of amino acid intake now.
