Are you trying to tell me you don't pop with your hips during a power clean? Because I can tell you as an experienced lifter you do. Weight belts are worn (too often) to protect your back during max lifts. Weight belts should not be worn during normal sets because it actually makes your back weaker.
Go look at Johnny Damon, Big Papi, Chipper Jones, Dustin Pedroia. They all start the exact same way. You have to start with your back side or you get no batspeed.
While Pujols has a great swing, each player has similar points in their swing.
