Plie' Squats

My wife, although still following exercise routines I plan for her has been looking for info on her own as well, (I know! pretty cool huh?) Anyway, she went to a women’s site and they had an article on squats. The Plie’ Squat
Seemed very intriguing not just because a hot babe was in the photo. It may be the same as between the legs squat, but I’m not sure. Has anyone heard of these? They seem like they would also be great for those of us who don’t squat to pee.
