A gym workout turned into an unthinkable tragedy after a woman fell on a treadmill and was flung to her death out of a third-story window.
The incident happened at a gym in Pontianak, Indonesia, on June 18, and the harrowing moments were caught by a security camera pointing at the treadmill.
The 22-year-old woman -- whom the Pontianak Tribune reported was being identified only by her initials, "FN" -- did not survive the fall.
The video clip started with people working out in a busy gym. At a bank of treadmills, a walking woman appeared to slow down to a stop.
The treadmill kept moving, however, throwing the woman off the back of the equipment.
The woman stumbled and then fell backward out of an open window positioned directly behind the treadmill.
Witnesses saw the woman on the tiled terrace three floors below the gym, prone and bloodied.
The video quickly spread throughout Indonesia and the world, racking up millions of views.
