Curve It Up
I used some of my favorite exercises from here and ab-workouts-guide.com to make my workouts... Sexy Booty and Core Blast they're a little tough but will tone your core and make your butt perky (lol).
If you like em try Holiday Hops, Abs Attack, Sexy Lean Legs, Multi-Plank Challenge their fun but challenging. Even if don't decide to do em. Checkout the exercises they have, maybe you'll get few ideas on what you like and create your own workout.
Good luck and God Bless!
