A Gym Contortionist?
Some people like punching above their weight at the gym in an attempt to show off, and here, you might think this guy has broken his back from his arch. Then again, his spotter would probably not be so calm.
The guy under the bar is probably stretching his back in a way that only he knows. Otherwise, what would be the purpose of arching like that? We’d have loved some back information on this one too, but like you, we can only let our imaginations wander. What do you think was going on here?
