my thoughts??? well with advanced individuals i believe you have to hit the muscle from different angles, and this may include excersises that you would probably normally not do. I know mountaindog1 had touched upon this subject before, you have to really get creative with your workouts the more advanced you get. You can still DC train but you may need to change up the excersises and get a lil creative with your selection.
I also am a fan of mixing up your training style, intensity, and volume every now and then... if nothing else it keeps me fresh and from being bored to death.
