(Rio de Janeiro, Brazil) After having a wild weekend in Rio at famous brothel Centauros, taking a couple of known prostitutes to his hotel, getting kicked out of his hotels, illegally graffiting the streets of Rio with 'Bielebers for Life', and getting pelted on the side of the head with a water bottle, Justin Bieber decided to take the edge off by doing a couple of pull-ups in Brazil, only, he couldn't!

Bieber was caught by the paparazzi attempting his best at doing a pull-up, but by the look of his face, we're starting to wonder if his great physique is mostly due to great contouring done with self-tanners rather than actual muscle.
