Kevin Bania is the holder of an unofficial world record after what you'll doubtless agree is a quite extraordinary jump.
From a standing start, Bania leaps from the floor up to a platform just over 1.63m high (64.4375 inches).
Amusingly, that's the same height as Victoria Beckham, so, if you can imagine it, Bania could just as easily have leapt on to her head, and (providing she kept still) landed and kept his balance.
At 5'10" himself, Bania can jump to within six inches (approximately 15cm) of his own height.
The 31-year-old Bania is a CrossFit athlete, a gym-based sport based on a variety of weightlifting, sprinting and jumping exercises.
