Best for Toning Exercises - Book or Video?

Body: 

I desperately need to tone my lower abs. My youngest will be two on Tuesday & I could pass for 4 months pregnant.

I know crunches are out - but I need some good exercise suggestions.

Which is more appropriate, the book or the video?

TY!

It has a great work out in the back. And you will get the bonus of the rest of the book.
