Well it's difficult to explain without visuals, but I'll try.
The inside loins are not the length of the spine. In fact they are only about as long as your hand.
So when hanging upside down, I cut the flesh that holds all the guts in. This causes the guts to settle into the chest cavity. Thus exposing the inside loins.
The loins are then easily removed without removing the guts.
Oh that sound........
That was me dropping the Microphone!!!!!
