Sooooo....I decided to sign up for an Insanity class.

There's a fitness studio by my house and they have a promotion going: 60 days for $60. I figured why not? Also, since I teach I've been using the excuse of time as an excuse to not work out. I teach until 3:30 then I stay after school almost everyday until 5pm prepping and working with my after-school clubs.
The classes are M-F from 8pm-9pm! I'm terrified. Feb 3rd is day one. I've never taken a class like this before but I need to do this. The woman who took my payment Saturday said that people usually quit after a couple of weeks. :
: She said "we usually start at 40 people in class and end up with 10." I hope to stick with it and to see my body transform after 2 months of hard work. I need some motivation and advice. Thanks. 

No advice, as I haven't quite worked up to Insanity yet, but good luck!!
