I also just bought Frank Forencich's two books, "Play as if Your Life Depends on it" and "Exuberant Animal." Now, he argues a different approach to workouts, but I am going to stick with Cosgrove's workouts for my "training" and model my throwing et al (as I honestly already have done) on the goanimal approach to fun and play.
This crap has to be fun. Oh, and not so damn scientific. You can measure and test and measure stuff all day and still not deadlift what my daughter Lindsay pulled on her first day of class.
That was a good lesson...for me.
