Clearly not satisfied by a regular workout, this is the frightening moment a man with epic abdominal strength decided to up the anti by dangling from a cliff edge in Brazil.
The incredible picture shows 27-year-old Luiz Fernando Candeia hooked onto a ledge at Pedra Da Tartaruga using just his feet, and no safety gear or protection.
A riot police officer from Rio de Janeiro, Candeia asked a friend to use ropes to lower him over the edge, almost 100 metres above the ocean.

Demonstrating incredible core strength, Candeia told the Daily Mail he then pulled himself up without the rope to get into position.
