If you want to see some in depth reviews try going to the videofitness website and look under instructor index. Almost all of the firm tapes are reviewed. I enjoy supersculpting, but I prefer Cathe or Christi's cardio to the firm cardio.
i use to love the firm... but its SOOOO DATED.... the hair, the clothes, the whole style.
I guess if you think of it as being retro. Yes the workouts are pretty good but the whole style - implants etc.. after cathe I just CANT see going back...
but if you can ignore all that then there are some good workouts - tho IMHO nothing beats cathe!
