I think you loose energy from the ground up. It's visible when you look at your right leg. It comes around your body and it is not travelling backwards. If you take a look at this you'll see that his right leg points backwards. I believe that is due to Roddick activating his glutes for hip rotation. If you fire your glutes more, I think the leg kick back automatically and you will have a power increase (that is if your timing has adjusted)
