Here's how to do it by Scott Herman: 

Interesting fact: You can enjoy full benefits of burpees right from day one of your exercise plan. Perform your burpees with no push up and no jump, you will be working your body just as hard but at your own level. 

I have never done more effective core and lower abs exercise than this one. Many people quit their fitness routines because they are no longer reaping any benefits any more, especially in that middle section area. No wonder, those endless crunches can only do so much and if you are serious about toning that core - do hanging leg lifts. This is going to shoot you up to another level of fitness, you'll notice this is worth the effort as you'll see stomach muscles showing, you'll be hanging on that pull up bar with a smile on your face.

Interesting fact: Fat that you collect on your stomach is more dangerous for your general health compared to the fat you carry anywhere else. It messes up with normal functions of your inner organs, like liver or heart. Strip it all off as soon as possible.
