I can prove you wrong
It's actually a very stupid advice..
Don't believe me?
Try yourself..
1:Go to a university or a place where girls hangout (Starbucks, tacobell)..
Wearing expensive cloths and driving a super sports car.. and just say them that they are beautiful and ask for her number,
2: bring the hottest guy you know to the same girl and ask for her number
I am telling you, no girl will chose sexy man or 6 packs over $6,000,000 and the rich guy no matter how he looks like..
So don't goto gym, goto work instead..
Staying healthy is a different story..
