San Carlos, California - WBO and WBC bantamweight champion Nonito "The Filipino Flash" is back in camp for his October 22 match-up against undefeated former WBO flyweight and super flyweight champion Omar Andres Narvaez (39-0-2, 19 KOs) from Argentina.

After his seven-month long layoff since knocking out Fernando Montiel in February -- the longest he's been away from boxing since he fought current IBF flyweight champion Moruti Mthlane in November of 2008 when he was sidelined for almost a year -- Donaire is definitely feeling the extra pounds he's put on.

Donaire, who entered his second week back in camp on Monday, is currently walking around at around 145 lbs. "I'm just trying to get back to where my body used to be, and pretty much just getting used to it again," Donaire told me. "I've been working with Cameron (Fort) my ART (Active Release Techniques) guy. There's just a lot of tightness; a lot of stuff that we're trying to prevent so I don't get myself injured trying to get back in shape."

Donaire also admitted that a move up in weight may be in the cards as soon as his next fight, as he has noticed a natural increase in his weight. "This is where I know that I'm gaining a lot of weight: The last time when I was out for a whole year, I usually just go up to 137. But this time, it hasn't even been a year or anything like that, and I'm around 145," Donaire revealed. "Definitely in the next fight, I'm moving up."

To help him whip his body back in shape, Donaire has been going through hell with his track and sprint training, under the watchful and stringent eyes of famed track coach Remi Kourchemny. Strength and conditioning coach Michael Bazzel, on the other hand, is focusing on getting Donaire's core back to where it used to be when he fought Montiel. Head trainer Robert Garcia and Jonathan Penalosa will be rejoining camp soon.

Last week, Donaire's promoter Bob Arum envisioned a fight between he and undefeated featherweight stud Yuriorkis Gamboa. Donaire told me that Gamboa is definitely an opponent he is gunning for in the near future. How near?

"By next year I should be able to fight in that weight class," Donaire said.
