What else do you do for cardio and weights, or has it been only The Firm up to now? The first 2 Cathe tapes I ever did were IMAX2 and Cardio & Weights, and I absolutely loved them both at the time! Now, they aren't the most challenging of Cathe's tapes for me, but that's 2 years later.
If you want a cardio and weight tape that's a little harder but not over the top hard, I would suggest Cathe's Circuit Max--it is fun, easy to follow as far as the steps go, and really effective as far as seeing results in a one hour workout. I would also suggest Cathe's BodyMax--it's real long (90 minutes), but again, easy to follow and you will get incredible results.
Good luck and have fun!!!!
