Farrell's Extreme Body Shaping... Am I Crazy?!

I have signed up for a 10 week challenge through Farrell's Extreme Body Shaping, which I will refer to as FXBS from now on. 

Basically this is a 6 days a week for 10 weeks high intenisty training in cardio kickboxing and and resistence band training alterrnating between the two every other day.  So M-W-F are kickboxing and T-TH-S are strength training.  

I am ready, but also a little nervous scared about committing to such a drastic work out regimen.
