Which fighters have developed power later in their careers?

All new accounts should have to stare at this post for 30 minutes before being able to post.

 

where did the OP mention race?

 

Junior Witter?

 

George foreman...... He went from 220/230 wild swinger/good jab........to 240/265 with more weight behind his punch using shorter compact punches and a clobbering jab. In his case speed wouldnt really be a factor he was still deceptively fast ( for his build) and timed his punches better as well where it landed on target adding to more damage.

 

Carried his power and his ache to his 40's

 

I am not racist though, I am the least racist on this site 100% I am a nice man with happy feelings all the time. If only 90 percent of this racist site can learn from me.

 

Hozumi Hasegawa and Sergio Martinez spring to mind. Povetkin too.

 

Golovkin was born with power in his two hands, so he is not one to be mentioned in this thread.

 

Povetkin really looks in an insane shape after the loss. It could be PEDS but still answers your question. I don't know if Canelo really improved his power after the fight with Mayweather, but definitely he improved his game.
