Barrios shared thoughts on his first training camp with Virgil Hunter, moving up and weight in more. Here is what the San Antonio-native had to say from Oakland:

“At 6’1, it was getting difficult making 130 pounds. I feel a lot stronger now that I’m fighting at lightweight. It’s also safer not to be drained going into fights. In my last fight, I killed myself trying to make weight.  I believe this is the right move for me.”

“I have a lot of respect for Virgil Hunter. He’s great explaining the fundamentals of boxing. He’s a great motivator and I’m looking forward to a bright future with Virgil. Everyone knows he’s one of the best trainers in the world so I’m excited to have him in my corner leading the way.”

“This will be a great card to fight on.  Jesus Cuellar vs. Abner Mares is going to be an all-out war. This will be the second time fighting at the Galen Center in Los Angeles. I’m looking to put on a great performance for all the Mexican fans that will be in attendance.  Everyone will see a stronger fighter when I step in the ring on December 10.”

“Training in California has been very productive. I’ve got a lot of good sparring and my strength and conditioning has gone to a new level. I feel powerful and I know I’ll be at my best when I step in the ring. All in all, it’s been a great learning experience working out here on the west coast.”

“I know he just went the distance with two undefeated fighters, so I know he’s durable. Fighters from Argentina always bring it. I know this fight will get rough at some point so I’ll be well prepared for anything he brings. I’m very confident in my ability to come out victorious.”

“2017 will be a year where I’ll get comfortable fighting at a higher weight class. My main goal is to stay busy and get as many fights in as possible.  I can see myself possibly fighting at super lightweight if I keep growing. I’m just going to take it day by day.”
