... um. Ma'm? I'm not sure if you're aware of it, but there's no way you're performing in an advertisement for a fitness product. Maybe that's what you were hired for, but that's either a Jessica Simpson video or the first minutes of a softcore porn flick. There's no way whatever the hell you're sitting on is a machine for "exercise," and even less of a chance said machine doesn't vibrate.
OK, maybe I'm being a little unfair. Maybe that tacky GIF is just an anomaly, and the product's official promo pictures don't make it look like an orgasmatron.
I'm not saying this is necessarily a bad product. Few things that are designed to make your ass slimmer are without at least a little inherent value. Still, I don't care how great a core trainer this thing is -- if you're willing to throw $400 at it, you might as well stick it in a place of honor in your living room and maybe glue a few dildos on it. Because there's no way in hell anyone who sees it is going to believe it's anything but a fancy Sybian.
