3rd round of P90X! Let's do this!

I started P90X at 250 lbs. I knew I wasn't already the usual smaller size that typical people start at when doing this program. But I saw one of the infomericals where a guy whom I believe was 250+ attempt it by just doing his best and did it in rounds. This will be my 3rd attempt and lost 50 lbs so far! I just "do my best and forget the rest!" Let's do this!!

PS, even my kids try to do it with me (as much as a 3 and 4 yr old can of course!)

Anyone else with me?
