Aiight Lesia - I got something fo yo AZZ!!!! Bring it!!!!

I don't think this one will challenge you like what you are looking for.  It's much less day to day work - it focuses on the intensity of the workouts that are done - not the number.  So you won't do more than three workouts a week - you seem to like more activity than that. 

 Thanks for that info Mack Mama.  I have some co-workers who are doing the  P90X and I know it's not for me!  But, I am hoping my Dr. releases me to start weight  training after I see him this week.  This book you are describing sounds like it's right up my alley.  I will check it out and report back next month.
