chapter premise?

Elsewhere I talked about how every short story needs a premise, a one sentence summary of its essence. I just finished up some critiques and it strikes me that every chapter should also have a premise. This doesn't have to necessarily be a single sentence, but you should be able to state clearly the point(s) of the chapter. Ideally, it would address the inner and outer plot arcs of the character(s).

If you can't state the chapter premise you need to seriously consider if you need this chapter.

Actually, writing the synopsis can identify these flabby chapters. If you have little to write in the synopsis about the chapter in question, maybe it's time to cut.

How about you? Do you have any tips for avoiding flabby chapters? How do you make sure your chapters stay on track?
