These photographs show the model with his weight taken by his legs. To achieve this he has had to press downwards with his legs, against the single nail which is supporting his feet. His arms cannot move sideways b can only swizzle about the point at which they are nailed through the wrists. He can now breath out but only as long as he can continue to press downwards on is impaled feet.
The legs have been straightened as much as possible but still remain bent, the head is thrown back and angle of the arms is made more acute. The price of taking a breath is the pain of pushing downwards on the impaled feet.
