Man, that's awesome that we started on the same day, my first was yesterday and I'm a little sore today, but I know tomorrow I'm gonna be unable to walk correctly lol. I'm doing the P90X diet and workout. I've attempted it before; it's supposed to be for 90 days. The first try I got up to like 50 days and I let life get in the way. But now things are more stable and I'm gonna finish this thing out! How long is the Insanity workout? like 100 days?
