This was an actual Hasbro product in the 1980s. There were five sets of exercise equipment aimed at girls. It looks like it was trying to capitalize on the aerobics boom happening at that time. The branding switched to Arbor Toys, who reissued in about 2006. Here's a review of the toys with pictures.
I am torn on this product. I love the idea of encouraging children to be active, but I hate the idea of talking to children about their shape. I wish the product name were different, and then brought back for ALL children, not just girls. I am not torn on the original commercials, though. They are fantastic.
