But that doesn't mean the former two-time heavyweight champions aren't capable of delivering a fight for the ages when they duke it out December 11 at Principality Stadium in Cardiff, Wales, to headline a Ring show on Netflix.

Fury (36-2-1, 25 KOs) turned 38 in August, while Joshua (30-4, 27 KOs) will turn 37 on October 15. Although two of the greatest heavyweights of the generation have lost a step, they certainly can still slug it out with the best of them.

When Joshua was asked who's closer to their prime at this moment, he didn't hesitate to say himself.

"Me. I feel fresh," Joshua said in an interview with The Ring's Mike Coppinger. "I definitely had a few injuries during my career, and I'm learning how to not just cope, but to get rid of these injuries. My body is very strong now. My mind is very strong, and I ain't got much damage.

"I'm well-versed. I'm very experienced. I've been in with some great fighters, and I can draw on a lot more experience than my future opponent, Tyson Fury."

Both fighters have been in their share of wars and battled adversity outside of the ring, especially in recent years.

Fury turned pro in 2008, and Joshua four years later after a gold-medal run in the Olympics. With 273 rounds across 37 fights, Fury has fought 98 more rounds in five more fights than Joshua.

Fury's fights average seven rounds, while Joshua averages five. Joshua's knockout percentage is 90%, and Fury's is 69.4%. They've been knocked down a combined 19 times (Joshua 11).

Fury and Joshua also share six common opponents: Oleksandr Usyk, Wladimir Klitschko, Francis Ngannou, Dillian Whyte, Otto Wallin and Kevin Johnson.

Exactly who's more shopworn remains to be seen.

"I definitely understand the science of boxing; there's no doubt about that," Joshua said. "And then just the way my biceps pump and my pecs flex are just additional add-ons for sponsors to take pictures of.

"We have to prove that this fight will live up to the expectations of being one of the best fights in British history."
