I agree that the workouts move quickly sometimes but I'm assuming the more I do them, the less I will miss steps. I also agree that the one 20-minute workout isn't challenging enough for me. I've been following an intermediate workout rotation (found it on another thread) which is 2 workouts each day and it's kicking my butt. Overall I think Firm express is a nice departure from the other traditional workouts but I wouldn't do it forever.
