Ichigo is not in the state of mind to do training on a form where he will lose his powers. He was only lucky that Kisuke was there to save his butt last time, so it was really all for nothing in the end :P

That, and I don't believe he can start communicating with his Bankai right now when he should be getting to the Soul Society and "save everybody".
