Why? Because there is real life precedent for it, and it would be cool as all hell. Muhammad Ali and Bruce Lee come to mind. They were perhaps two of the greatest physical specimens ever seen. The feats that they performed were Godly and have yet to be replicated. Spoiler Bruce Lee playing ping pong against two men while using nunchucks: Bruce Lee demonstrating the "One Inch Punch": When given 6 inches: Two Finger Pushups: Ali incredible footwork: Even more incredible reflexes: I found a pretty cool article from Scientific American on whether or not a real life Batman could exist at this kind of physical peak. Here are some excerpts: To be clear, I'm not asking for a Batman that can beat Superman in a head up fight, because I know how that gets you Clark fanboys in a tizzy. What I am asking for is a Batman that is superhuman by our standards. Based on our frame of reference, in a world with no aliens (yet), Batman would be the closest thing to superhuman just in terms of his feats. As evidenced by the gifs of Lee and Ali, the feats they are performing are superhuman to us. They were at the peak of human conditioning and masters of their craft all while doing things that I'm sure 99.99% of the population could not. Nolan's Batman was kind of underwhelming in this regard. Although the training montage with the League in Begins was made up of the kind of stuff that should have produced a high-peformance, olympic-level Batman, it didn't translate into his skillset as much as I would have liked it to when he actually became The Batman. Balancing on wooden beams while taking blows from every direction to improve bone density and toughness is cool looking, but meaningless if he doesn't do anything cool once he puts on the cowl.
