Books, but then I've always learned best from books - you set your own pace, they are easily cross-referenced and indexable, and to top it all off books are more often than not structured and well-organized. Re-reading is also an option. I point out all these things to contrast books to lectures or coaching, or even videos; they're just not the same or as good as a good book. As for specifics, if you haven't read it already, "The Pragmatic Programmer: From Journeyman to Master" is excellent and a great place to start, and one of their biggest tips? Read books, at least one per quarter.
