Hi UltSoccerMom!
First of all, GOOD FOR YOU for getting the videos!!!
I have used The Firm before and I agree with you!! It is pretty difficult at first and they do move on pretty quickly. BUT, (yes, there is always a “but”), I think that it really does produce results. The thing that helped me was to keep in mind that as long as I was moving and keeping my heart rate up, I was doing good. I have been using the video for about three years now and there are still moves that I can't get right and I just don't bother with anymore...So, when the they are doing a move that I am not good at, I just keep doing a move that I know I can do and enjoy. Or, if they do too many sets and my legs are getting too tired I just switch to a different move and keep going. Also, I think the same way you do about going to a gym and seeing all of those skinny women! I was so happy to hear that I am not the only one who feels that way. Keep up the good work, just keep moving, you're on the right track!!!
