most people incorrectly believe you get ripped abs by doing ab exercises. not your fault, that is clever marketing. we all have seen those absurd infomercial scams where they try to sell you some contraption and they have a ripped dude smiling as he does it. so of course a fat person watches that and thinks he got that way from using it.
the truth is there is no point in even working your abs if they are covered up in fat. so lose the fat!
and you lose fat from diet.
