Gennady Golovkin looks in fantastic shape at the age of 40 as he took to the scales ahead of Saturday's fight against Ryoto Murata.
Golovkin and Murata face off at the Saitama Arena on Saturday, four months after the fight was originally supposed to take place in Japan.
GGG holds the IBF middleweight belt and faces WBC title-holder Murata in a massive unification bout.
The Kazakh boxing legend came in at the championship limit of 160lbs, with his opponent also making the weight comfortably.
Those standing nearby politely applauded as Golovkin showed off an impressive physique before he respectively faced off with hometown hero Murata on the stage.
Speaking to BoxingScene.com, Golovkin said: "It is a challenge when fighting in a different country, especially if that country happens to be my opponent's homeland.
"But it spurs me on even more in training camp. Now that I am in Japan, the adrenaline is starting to pump. I am really excited to be here and to fight in front of the fans in Japan.

"They really love and appreciate good boxing.
"Murata is a good, solid fighter. There is a reason he has been an Olympic gold medalist and is a two-time WBA world champion. He came to my training camp in Big Bear many years ago.
"We sparred a little. He was a very serious fighter. He worked very hard in everything he did in camp, inside and outside the ring.
"We got along very well. I am going to be 40 on Friday but I feel good. I will continue fighting as long as I feel good and can train hard to fight at the level I have come to expect of myself.

"Living a healthy lifestyle keeps me feeling good, strong.
"Murata is the most important fight. Period. I do not look ahead.
"I have been fully invested in training for the fight I have in front of me. I have too much respect for Murata and his body of work.
"My focus is on him and winning his title. That is why I am in Japan. I look forward to fighting in a packed arena.
"I have missed that energy. It is going to be exciting because we both have similar styles of fighting. We are both power punchers, we are aggressive and we come forward.
"Diamonds cut diamonds and on Saturday, there will be two diamonds in the ring. It will be a boxing gift to the fans I expect it to be the fight of the year."
Eddie Hearn has also warned Golovkin not to underestimate Murata when they meet in Saitama on Saturday night.
The Matchroom promoter told DAZN during an interview last week that he could be in for a rude awakening if he does.
