Her other post is an inquiry about jerseys. How do you know that one wasn't the first one?

I didn't realize there were requirements for what a first (or second) post had to be about.

Hi Pirate Kitty, don't let the invisible rules that you didn't know about get to you.

anyway, I don't know the Insanity work out but off the cuff it looks like PX 90 and related. Just don't hurt yourself pushing too hard, and make sure to do things correctly. The problem with in home workouts is that there's no supervision by knowledgeable trainers who can assist you in doing things correctly. I only say this as my PT has seen an upswing in business from Crossfit, PX 90 and other hardcore workouts.
