Although he recently revealed that he is looking to slim down a little against the ’12 round fighter’.

Joshua, 31, showed off his current build in a recent Instagram post.

And while the Watford-puncher is looking thinner, he still possesses bulging biceps.

He captioned his post: “Heavy hitta 💥”.

Joshua recently revealed his game plan regarding his body shape going into the Usyk fight later this month.

He told Sky Sports: “I do look at my weight but I’m not trying to make weight because I’m a heavyweight.

“I tailor my training. I am getting a lot of experience, I’ve been fighting good fighters for a long time, I’ve studied them and learned about their training camps.

“I’ve learned how to condition my body for specific fights. I’m looking trim for this fight.

“I’m fighting a guy who is a 12-round fighter. So it would be silly of me to go in there bulky with my muscles screaming for oxygen.

“I’ve been training like a 15-round fighter in this camp. I will be well-conditioned to fight. That is key.

“What happens when I train that way? My body adapts and takes its natural form. This is the form it has taken.”

Joshua’s career-heaviest as champion was the 18st 2lb he weighed in 2017 before beating Carlos Takam, now 40, in ten rounds.

And his lightest was 16st 13lb, when he outboxed Andy Ruiz Jr, 31, in their 2019 rematch having been stopped six months prior.
