I would warn you not to order P90X unless you have done other Tony Horton workouts. He has the type of personality you either love or hate. I bought PHH and I only previewed it, I couldn't do it because he grates on my nerves. But I guess you could always send them back if you didn't like...
I'm not sure if you want to go out and buy more equipment, but Wal-Mart has plates that are shaped like Hexagons but they have cutouts so you can hold them. I think it would make the pullovers easier.
Thanks everyone for your replies. My heart tells me that my son is going to come before his new due date. That's just my motherly instinct. Thanks again.
