I agree! Just because it's and 8 week program doesn't mean it must take 8 weeks, I've thought the same thing and may do each week twice to make it 16, or until I successfully complete the stage! Good luck!
I am 38 and a mom of 3, I just finished week 1 and already can tell the difference. At the end of day 1 I almost couldn't finish, but was able to finish day 3 with ease. It's really nice to read all the encouragement from others and see that this program works!
