I have found a new form of exercise...guaranteed to give you six-pack abs or your money back!!!!
All you have to do is catch a cold, or the flu, or pneumonia...which ever floats your boat.
Then when your lungs are filled up with fluid, just start coughing....and coughing.....and coughing.
Try to take a deep breath (that is if you can get past the sharp pain in your lungs).
Repeat for as many sets necessary for desired effect, believe me...you won't be able to stop yourself.
Your sides will begin to feel the effects after 4 continuous days of this.
(I want my money back.)
