I have to disagree, my own experiences and that of bodybuilders from the 'golden era' have shown considerably better fat loss with higher volume/lower intensity routines.
Something similar to what i'm currently doing is optimal for me. Slowly increasing workload during pre-competition times is a classic method used by Park, Reeves and co and well documented by McCallum.
Just like Full-Body lifting, and concentrating on the basics I believe it's a method which was lost in the shuffle during the drug era days. However this method has not yet been embraced back as well as Full-Body routines, but I believe it should.
