The Core Moves
Every ab exercise from The 21-Day Shred.
It's always best knowing what you're walking into, good or bad. The good thing about The 21-Day Shred is that you're actually going to see some serious results.

If you're up for the challenge, go ahead, download the app for iPhone and iPad devices. And if you don't have iOS, grab your copy of the PDF.
In the meantime, here's every ab exercise you'll do battle with.
