Boxer POV shows how little time you actually have to react to punches

Time is, generally speaking, of the essence when playing any sport.

While it's obviously crucial to be fast if you're a runner or even a swimmer, this video is proof that boxers really are in a league of their own.

This video is a fascinating watch as most boxing fans only ever get to see the game from the side of the ring, but thanks to a GoProCamera, they might as well be fighting themselves.

In the footage, the two men can be seen receiving advice about how to up their game as they skilfully react to punches from one and other.

The amount of hand-eye coordination involved is incredible, and it becomes clear within a minute or so of watching that this game is not only about physical reflects, but mental stamina and reactions.

Reacting to the sparring footage, one impressed viewer wrote: "Definitely gives the audience the proper perspective of the fight and honestly does show how difficult it is when actually face to face with the opponent.

"It's easier to see the fight and be able to call out openings when watching from the outside, but it's entirely different when actually in the ring."

"This might really help someone get a glimpse of what it's like," chimed a second.

While a third observed: "I love how the camera starts getting blurry when he starts pummelling you lol. Great job, and excellent perspective!"

"It always looks so easy from the outside!!!" wrote another.

"My first real martial arts fight ended in less than 2 minutes after being flawlessly kicked in the head two times... Didn't even see them coming [sic]."

All of which begs the question, would you be willing to give boxing a go or would you prefer to watch from the sidelines?
