If you think you're in good shape, P90x will definiitely make you reconsider.
I decided to download a few to see how i liked it. It is BRUTAL. But they are true to their word, in 90 days, theres no way you couldn't see a change in yourself.
Its well worth it, but I recommend doing their test first. I'd link you to it but I have forgotten it.
Like Sheryl said above, try Power90 first, see how you do with that?
The trainer is really fabulous too, some of them are annoying, but I actually really enjoyed him.[And Chalene[didnt spell right] from Turbo Jam.
