That may sound like a simple observation ahead of his Road to UFC Season 5 bantamweight semifinal against Japan’s Ryo Tajima in Shanghai on August 28. For Koren, though, the difference between this camp and the one that preceded his quarterfinal is significant.

When he arrived in Macau for the opening round in May, Koren had accepted the fight at short notice after initially being named a backup. He missed weight before facing Japan’s previously unbeaten Ryuho Miyaguchi.

Still, inside the cage he delivered one of the more impressive performances of the opening round, dropping Miyaguchi with a left hand before finishing him with a rear-naked choke at 4:00 of the second round. “It was very different.

In the last bout, I just did sauna and tried to lose weight. “This time, I was at home for three months.

I rested for 10 days. After that, I went for training.”

A different camp, a different KorenThe weight issue is something Koren is not avoiding. It was an unwanted footnote to an otherwise important night.

But Koren admits that the bigger problem was what happened after his previous defeat. In August 2025, he lost his Matrix Fight Night bantamweight title to Nepal’s Rabindra Dhant.

The defeat came after Koren had already seen an earlier Road to UFC opportunity disappear because of contractual obligations. “Last time, [when] I lost; after that, I got depressed.

I was thinking that I was going to go to the UFC, but I lost. “I used to eat healthy food.

I used to do regular training. [After that] I didn't go out of my house.

I used to eat whatever I wanted. Because of this, my mental and physical condition went down.”

“If we want to fight, we have to be disciplined. But I lost my discipline.

That's why I could not lose weight. Now, I want to eat healthy food.

I want to maintain my body. The numbers tell part of that change.

Koren says he came into the previous fight around 71 kg and is now down to around 66-67 kg. There has been work on his game too.
