You seem to be very informed about STS and I am hoping, if you have time, you can answer a few questions. I am still on the fence, like a lot pf people, mainly because of the price. Cathe's workouts have challenged me in ways I never thought possible. I LOVE to exercise and she made me want to be the best I can be, physically. I am definitely up to the STS challenge, but I am confused as to what happens after the program is completed. What do you do to "maintain" this muscle you have created? Can you repeat the series, or is this a one time deal? I am running out of time to preorder and I still don't know what to do. I will only be saving $40, and I guess I could sell on ebay if I really don't like. I am so confused!!!!
