It designed around trying to create functional strength and explosiveness. A good example taken to the extreme, because it follows a similar workouts pattern, are actors in the movie 300. It also what BJ Penn uses as part of his training for MMA. Google the "Fight goes bad" workout
At it's core, it designed around Olympic style power lifts (explosive strength), gymnastics (flexibility and strength),plyometrics (explosiveness) and intense cardio workouts (like rowing, or sprints). Most of it is done for time, one exercise after another with little breaks.
You do the standard warm-up/workout (3 Sets of 10 to 15 reps of push-up, pull-ups, back extensions, overhead squats, sit-ups) then do the workout (either called Girls or Hero) of the day. Today it is
3 rounds for time of:
Walking lunge, 100 ft
25 Back extensions
The good thing about it, is that is scalable and you can sub body weight exercises if you don't have the equipment.
You are not going to bulk up like weight lifter, but rather you going to look like Triathlon if you watch your diet and do this.
