I am an exercise video fanatic and have several of the Firm videos including all the Classics except Volume 5. Currently, I am doing The Tortoise, Upper Body, Standing Legs, and Tough Aerobic Mix in my rotation. These are all great. The thing I don't like is that the cardio portion of The Tortoise is an attempt to do ballroom dancing on a step. I love the exercise sequences in Tortoise so much that I just ignore my opinions on the ballroom steps and ballroom music. The ballroom sections are simply a nice rest break from heavy weights. Using various Firms combined with running and Atkins, I dropped from 21% body fat to 19% body fat and got my arms about 80% looking like those of Linda Hamilton on Terminator 2. I recently added low volume high intensity weight training, each body part once per week, and lost two pounds/1.8 inches in a week (I think eventually my pounds will go up).
