I have seen that many people are trying to sell a "system" for getting abs in a few weeks.  It is not possible.  Abs are a committment to hard work and a devotion to improving yourself.  I am genetically inclined to have a six pack and it took me two years to develop it.  When someone says that 4 weeks is enough they are either trying to sell you supplements or get you to pay money for a program that will not work. . . .but they will laugh all the way to the bank.

Hard work and a true desire to improve your body are the only answers to the six pack abs question.  Forget the snake oil salesman telling you to buy something to make it happen.
