If you decide to go with the 4 week free trial, make sure you cancel at around 3 weeks.
The reason is, Jillianmichaels.com will charge you at 3 weeks 6 days, instead of 4 weeks. In other words, if you signed up on January 1st, the day of the 4th week is January 29th. However, they will charge you on January 28th. When you ask them why, they will say that the trial program officially ended earlier or something, that the 1st day is counted as well.
I signed up and got screwed over with customer service so stuck there now for few months, just wanted to check out the free 10 day offer. Can't see point of joining when can get the books or are they very different? I know people there say message boards are great, IF you have time to spend reading thru it all everyday! Many are "Jillian Volunteers" too which sounds pretty biased!
BlueSquares - thanks for the blog post, did read it and I agree. I am not even using her food program, I have my own, just more interested in her own ideas on exercise. I gather I can get that from the books, altho now wondering which one, do I need both? Wish could get out of library, the Master Metabolism one is there but not other ones.
