Bravo star and fitness instructor Greg Plitt did NOT die from stumbling on a railroad track Saturday ... he was fatally struck by a train after trying to outrun it ... to prove the effectiveness of an energy drink.
....
The video shows the train closes in on Plitt as he races at breakneck speed, but he loses the battle and the train "clips" him ... throwing him off the track to his death. It happens quickly and after getting struck he disappears from the video.
there's a video?! wtf
