Flat Stomach

For many people the idea of a stomach workout is doing 200 super fast crunches in a row and getting over with it. This is not the best way to train your abs.

Slower controled crunches are much more effective. And 3 sets of 25 quality crunches will give you alot more benefit then 200 or 300 crunches done the wrong way.
