I'm a big fan of success stories too!
I bought the original Tranfirmer (at least I think it was the original--blue box that had legs you could pull down to make it higher or lower). I did one workout on it and then it collected dust in the basement for several years.
I had been a member of the YMCA for about a year so I could go to the classes (I love group classes), but my schedule never seemed to coincide with the classes, so it was a waste of money.
One night, I couldn't sleep, so I turned on the t.v., and watched an infomercial for the newest Firm workouts. The next day, I went to Target and bought the Transfirmation system (the one with 2 separate boxes that can be stacked or set at an incline).
I started in October and have seen some amazing results! My arms are looking much more defined, my legs are looking good, and my bum has definitely "lifted". I've lost about 12 inches overall, lost 20 lbs (have added 4 back since the holidays
I just bought about 20 of the classic firm tapes (the Firm site was having a huge sale), and those are really tough! I laugh at the outdated hair, makeup and workout clothes, but those are some seriously hard workouts!
I've slacked off a bit because of the holidays, but I'm ready to get back into it. I try to do 3-4 Firm workouts weekly, and 2-3 HIIT workouts on the treadmill.
