If you want your body to change, you've gotta shock and traumatize it. I'm going to be doing a whole series of ways you can shock and traumatize your body. I'm also going to be doing a write-up that breaks down this concept and explains WHY it works. For now, give this a try on your own:
-Sprint (til you slow down significantly and your body is shocked)
-do bear crawls (til you slow down significantly and your body is shocked)
-do push ups (til you burn out and hit failure)
-do crab crawls (til you slow down significantly and your body is shocked)
