I made the same mistake a couple of weeks ago. Someone asked on a thread how to work the center of their chest, I suggested butterflys. Needless to say Eric and Sleazy set me straight.

If you go into the gym and watch other people you can see that they have been subjected to the myth. They continously hit the straight, decline, and incline bench. If you read heath magazines, full of BS by the way, you find the same thing. People hear this so much they think its just a bodybuilding must.
