Anthony Joshua: Nigerian-born boxer arrives Saudi Arabia for Usyk vs Fury

It's obvious that Anthony Joshua is keeping himself in shape while he's in Saudi Arabia.

Ahead of Tyson Fury's undisputed heavyweight title bout against Oleksandr Usyk at the Kingdom Arena on Saturday night, "AJ" recently traveled to Riyadh and is making the most of the chance to maintain his outstanding physical condition.

The WBO, WBA, WBC, and IBF belts are up for grabs, and the former two-time heavyweight champion will be in the front row for both fights.

If the two decide to invoke the rematch clause in their contracts, Joshua might have to fight the victor later this year or contend for the IBF belt.

The 34-year-old gave himself a new nickname in the caption.

He wrote, "Quadzilla," alluding to his protruding upper limb muscles.

Fans lauded Joshua's remarkable body and unwavering work ethic in the comment section of his post.

On Instagram, Joshua posted an additional photo from his trip to the gym.

This comes as Joshua is set to return to ring in September.
