Is ferocious punching power mostly genetics?

For people with great timing

 

Good point. Roids dont hurt.

The myth of genetics has been debunked. Look into Ray Comfort, who has been debunking stuff like this for decades.

 

This is a pretty interesting breakdown. The author breaks down punchers into 3 main types with examples:-

The Brute
Typical Examples: Sonny Liston, George Foreman, Earnie Shavers

The ultimate in heavy-handedness, these boxers do not necessarily have the speed to be explosive of the long limbs to generate leverage. Often, their power seems to some from nowhere and there is no better example than the demolition of Joe Frazier at the hands of George Foreman. This is the same Frazier that went life and death with Jerry Quarry, Muhammad Ali and Ken Norton, but what battered from pillar to post by a foreman that did not look like he was trying for one second.

The Grenade
Typical Examples: Roy Jones Jr, David Haye, Mike Tyson

While being different shapes, what unites these boxers is their ability to use their athletic ability to generate significant speed and with it, force. Often the kings of the highlight reel knockouts, they are among the most loved boxers. However, these athletic gifts do not last forever and over time, the knockout percentage drops, in contrast to the brute who never loses the ability to punch.

The Catapult
Typical Examples: Thomas Hearns, Alexis Arguello, Deontay Wilder, Vernon Forrest

These boxers are usually the tall and thin fighters with high knockout percentages. Their power cmes from their incredibly long levers. Many of these boxers possess well above-average limb length, with a correspondingly below average torso length. It means they are able to generate great momentum through accelerating over a greater distance. Knockouts such as Thomas Hearns stopping Roberto Duran are testament to the damage a punch can do when given time to reach terminal velocity.

Anecdotal but I definitely feel more impact hitting the bag when my back fills out from doing rows.

Punchers are born not made. You can look as solid as you want and train as hard as you can but you either have it or you don’t. Look at Tim Bradley. Strong man with a good build who looks like he could punch. He’s pillowfisted asf. Look at Tommy Hearns. 6”1 welterweight who was lanky and lean but could punch like a mule kicks. It’s genetics.

 

Ferocious

 

Are you a pro boxer?

 

And yet, listen to the mitts as Tim trains with Tommy. At 3:20, Hearns shows him to throw from the shoulder and the jab is noticeably stiffer. Later his right hand also improves with a few adjustments. There's definitely a genetic component, but it can only be maximized through technique.

I don’t think it’s meant like, “this is my DNA, therefore I punch hard.”

But rather that some people are more naturally athletic than others, and that athleticism presents itself in it’s own unique way. There are many sports that require great physical individual qualities. You’d be hard pressed to find one that didn’t require the individuals to be born with a natural advantage at the top of the game.

Bolt trained hard, no doubt, but he was clearly freakishly fast naturally.

Messi trains hard, no doubt, but his balance, reaction time, general technique, and footballing IQ was already superior, or the ingredients were already there to make him superior.
