The gluteus maximus is the largest muscle in the human body and the butt is one of the most well padded areas. You know, for sitting on. Like a cushion or something equally not-at-all-painful.
Naomi's finisher is undoubtedly a nod to her ample booty but come on. Never mind the fact that a larger behind would have more padding and hurt less, the amount of force that you could conceivably put into jumping simultaneously backwards and up to head height would be about akin to bumping a drawer shut with your hip.
