"Have buttered scones for tea."
Seriously: I think it's all about core work. Ask yourself what part of the body you feel is being used. That's the part it works.
How will it "help"? Any strengthening of any part of your body is a good idea, which is why, for instance, some coaches eschew straps for lifting heavy: they want you to improve your grip strength by having to hold the weight unassisted.
It's a half-assed answer, i know, and you probably want more. But at least I didn't say "Put on women's clothing and hang around in bars."
