Ever wondered how Santa gets from rooftop to rooftop without moving the sleigh? I never knew he was so nimble!

What Santa is doing in the video is called "Parkour" which is described as a holistic training discipline using movement that developed from obstacle course training.

Practitioners aim to quickly and efficiently overcome obstacles in their environment, using only their bodies and their surroundings to propel themselves; furthermore, they try to maintain as much momentum as is possible in a safe manner. Parkour can include running, climbing, swinging, vaulting, jumping, rolling, quadrupedal movement, and the like, depending on what movement is deemed most suitable for the given situation.

So much for Santa being a jolly old fat man. Maybe we need to leave protein bars and energy shakes instead of milk and cookies!
