Get a Toned Tummy Just Like Britney Spears With These 4 Easy Ab Moves

This one is simple, but Britney adds in some complexity by holding a bar above her head for even more stability. Be smart like Brit, and keep a steady pace. Don't race through them, and you'll feel the burn!

We've heard that Brit does anywhere from 500 to 1,000 sit-ups per day. We all know how to do sit-ups. Just get on the floor and start moving. Don't bounce your way through each rep. Instead, take a slow and steady pace throughout.

Why do a V-sit when you can balance yourself on a bench and crunch your knees to your chest while maintaining balance and forcing your core to do all the work? Britney's abs know the answer, and so will yours! Make sure to focus on raising your knees up, instead of just forcing them toward your chest. Use your lower abs to make this move really burn.

There's nothing more important that total body strength for your core, and yoga is a great way to get your abs popping.
