Insanity

I decided to kick it up a notch this week when Todd suggested we try out the "Insanity" workouts. They are a mix of high-intensity cardio/circuit/jumping/core/sweaty/craziness. So far I love them and I don't feel like they are making me too tired to run. OK I've only had 2 runs since I started on them but I felt ok on both of them. I am however so sore that it wakes me up at night when I move, roll or shift in my sleep. Is that a good sign? I don't know. Word on the street is that I will probably be sore for about 2 weeks. Oh boy. I'm very excited that my core is killing me - I need lots of work there.
