Back when I was in college there was a show called Kiana's Flex Appeal, featuring a hot Asian-Hawaiian fitness instructor. First I watched it to check her out, but she knew her shit and I got some good workout ideas from watching her.
Something kind of related, I know that in the Israel Defense Forces young female instructors teach the new male recruits how to use firearms. They found that guys focus and retain a lot more when the instructor is an attractive woman. Same with these exercise shows. It's hard to forget what you learn cuz you have a vivid mental image of it.
Here, I found Kiana. They always had some hot guys on the show with her, to get the female audience too.
