CG, the soreness will subside as you adapt to the program, then you will be able to crush it even more. DC training, or styles of it, have worked better for me than anything else when packing on muscle. I usually have to ease my way into the program a few weeks myself, and this is one of the reasons why Dante usually states it is not for everybody.
Yea, the eating will cause stomach distention....sucks, but it works out in the end afterward. He'll keep an eye on your BF levels and will then probably incorporate mini cuts at that point as needed. My gut sticks out in my shirts and people at work make fun of it, but when I lean down, it goes away. Well, in the morning it looks better too.
