The personalities of each of the girls are a little to generic. At least by anime standards. So far we have had, the cute girl who loves sweets, the flat chested girl who wants bigger boobs, and now the rich girl who is the perfect Japanese woman/ house wife or will become such. It makes sense their really isn’t a story line, except for lets work out, so having generic characters that aren’t going to be developed makes every thing easier.
The exercises them selves, are decent work outs. Again you are going to have to do more then one set but they are not fooling around. They are tough work outs and will get you in shape if you do them. Also, learn the dance and that could be really good warm up/ cardio. I might start using this as part of my work out routine.
