Course it's not magic.
We learn to perform it. Impact is a matter of acceleration and mass.
So the space doesn't matter, it's the acceleration you put into the punch. And using your heels, hips, shoulders, elbow and wrists appropriately you can maximise the impact.
And the "secret" to be able to do it, you must relax. If you squeeze your fist, you'll bend antagonist muscles which will impede your quickness. Eventually, at the impact your fist will be squeezed whatsoever.
Oh and you have to hit with some sort of pull and punch attitude, which means you pull one shoulder back while you hit with the other arm.

And actually, the one-inch punch isn't performed the way it is in the movies, that's just for show and movement readability for the folks. We don't point out with one finger on the chest before hitting. We just strech the hand flat and as soon as we have contact with the partner's chest, we roll our hand over forwards to a fist and hit. That's why it's called the one-inch punch: because the distance covered should actually be the length of the middle finger's distal phalanx (which is an average one inch; much closer to the one-inch punch than the one seen in the movies eh?).

As for most things in this world, there are three secrets to success:
– practice
– practice
– practice

Just to make it clear: in real life, a one-inch punch won't send anyone flying (except you're a 30-year-old guy facing a 10-year-old child). But it will hurt, shock for a second and cause the opponent to step back because of loss of balance.
Still quite effective if you ask me.
As a drill at least, because in a real-life fight it'll be difficult to do a propper one-inch punch. But it trains you to release the largest amount of force within the shortest amount of time possible, which makes you hit harder and quicker in time.
What's more, when someone hits you with this kind of accuracy and velocity, you will hardly block it. And even if you manage to get contact with his arm, the fis will still hit you. With less impact, that is, but nevertheless this will give him a psychological advantage over the fight.

styleyk says:

The footage he is using to help him explain the one inch punch, is crap (the film was nonsense, the Lee family hated it) and misleading. He should have used the real footage of Bruce Lee at the long beach tournament instead, also the punch has its roots in Wing Chung.

Joe Farmer says:

Too bad that Lee didn't actually fight anyone at the Long Beach International Karate Championships as claimed by the movie.  In fact, Lee had one of his credulous, fawning, and deferential students make very sad pre-scripted "attacks" against him, which he then countered with his kung fuwie.  Only the most gullible of shit-stained, retarded kung fuwie and Lee-hole fandicks would be impressed by this "demo".  Also, you should first actually research the claims Lee-hole made regarding the dumb inch punch fraud before coming up with an analysis based on what you think the dumb inch punch was.  Actually, any person of low-average intellect can easily discern that Lee-hole was either pushing people or using confederates in on the gag.  If your analysis is accurate, you should simply test it.  You will find that results depend upon the technique; pushing versus stopping at the target.  In other words, your analysis can be ignored because it starts with missing and/or faulty premises and secondly, you've failed to actually demonstrate your theory in any sort of credible experiment.

I think that it’s also because it’s usually performed on the solar plexus and that hurts like hell if you do it on the right spot

Is chi real? I seen some cool stuff, but I wondered if science can explain some of those incredible feats.

Dudensky says:

Y-yeaaaah… you do realize it takes weeks (if not months, or even years) of training to learn it? Lee punched hard, because his joints were insanely strong.

Priyo Das says:

you deserved a dislike from me cuz Bruce Lee doesn't follows physics , he feels it and one can never be able to do those things without feeling and just by understanding physics !!!
