The article and above comments are basically saying that you don't need an expensive gym membership and a highly qualified personal trainer to get six-pack abs. You can do it yourself by, as you note, by building muscle, burning fat, and eating healthy.

Period. Those unwilling or unable to change their lifestyle would be best served by finding something else to do with their time.
