How did Michael Spinks hit so hard at light heavy

He looked so skinny and lanky. In fact, how did Bob Foster hit so hard?

 

Dunno. It’s the same situation with Wilder at heavyweight.

 

But Wilder has visible muscle on him. Not bodybuilder type like AJ, but he is muscular

 

Isn’t this the Tommy Hearn’s phenomenon? Maybe there is a biomechanical explanation why lanky guys can sometimes hit.

 

Body mechanics. It was the WAY he threw his shots. Power seldom comes from muscle. It’s how your weight and momentum is manifested through technique. . Tommy Hearns was tall and skinny at welterweight but he hit like a truck and also carried that power up to the higher divisions

 

Muscled arms aren’t where power primarily comes from.

 

Listen, power isn't about muscle, it isn't about technique, it isn't about speed, or shape or form. Punching power isn't about genetics or force. Punching power is about-hold on, I think Amazon is delivering this cool soup ladle I got that I can just hang off the side of the pot. I'll explain this later. You're definitely going to wanna hear about this.

 

Well guys like Mike Tyson, George Foreman, Mike Weaver, Frank Bruno, Razor Ruddock etc were muscular guys and they hit like they look

 

Yeah Hearns was another one. Tall and skinny but could put your lights out

 

There’s also musclebound fighters who don’t hit hard.

Fat guys who hit hard, skinny guys who hit hard, etc.

Force = Mass X Acceleration.

 

Spinks hips turned his shoulders. All there is to it.

 

Let Apollo teach you the secret.

As others have mentioned, muscles have nothing to do with power. It's about the pivot and follow-through.

 

Power is natural for some. and sound technique increases it. Spinks had both

 

There is. They get excellent leverage. Especially
Foster, Spinks, and Hearns.
Also being well schooled helps.
