Figure 8 Fitness

My sister has lost a lot of weight doing something she calls figure eight fitness.  She told me it was toning without bulking up with muscle like a body builder.  I don't think it involved using supplements or anything like conjugated linoleic acid but she's definitely lost weight. The picture I saw of her shows a big change.  I can't tell what her muscle tone is like from the pictures but I have never seen her this thin before.  I am hoping the picture was at a bad angle because now her head looks too big for her tiny body.  I really hope it was a bad photo.  I'll see next month when I see her again.  I'm curious to find out exactly what this program is.
