Core Trimmer (helps situps)

Ok, I say it helps situps but it's for supporting a lot more exercises. I just have not used this and currently cannot, so it's time for it to go to someone who will use it. As one good website puts it: "The ideal way to tone your entire core, upper, middle and lower abs plus the obliques. You can also tone your forearms, triceps & biceps." It is in pretty good shape, though it does have a squeak to it when used (I haven't put oil on it to stop it yet). I've priced it low so someone can get it quickly if they would use it.
