Yeah, those carb up days rock. I would gain about 5-7 lbs. from Thursday night to Saturday. During the power workouts on Saturday, my muscles felt so tight, like springs. Good stuff...
I would encourage you not to split the depletion workouts up. Follow it according to the book. But that's just me and I'm kind of OCD when it comes to that kind of stuff. Those workouts will actually get easier as time goes on and your body adapts to that kind of training. Tough it out and it will get easier.
