Hello Cathletes, thanks for the great opinions - I trust this group so much. I looked at the book and honestly, it seems like they are not quite "challenging" in my opinion - nothing new.
In fact, Rachel Cosgrove says to weigh your purse and then double it and that will be the weight you will use for the workout - WHAT!!! Cathe is still by far the best and the most superior instructor out there. I have other programs but honestly Cathe is the only one that I've gotten results = Cathe knows her stuff. I have LIS, XTrain, STS, Crossfit and many more that are challenging, awesome and fun. Like Clare mentioned, I don't need anything else, Clare's right.
