Shawn, you are not kidding, today I did my slim in 6, the ramp it up, I think..anyway, I can't make it all the way through, the leg work on the floor, Burns like there is no tomorrow!!! I also go to the gym and do cybex/circut training 3 days a week, I would like to keep in touch in this thread and see how you are doing on the sI6, as far as inches and everything! Today is my 3rd day doing the video's so were in about the same place. Do you use the ab one?
