Former interim World Boxing Association bantamweight champion Hugo Ruiz is from Los Mochis, Sinaloa, Mexico.

25-year-old Ruiz is trained by his father Heriberto and twin brothers, Edel, who takes care of the mitts and technique and Heriberto, who takes care of strength and speed. His physical trainer is Juan Fontanills from Cuba. His dietician is his mother.

My brothers were the first generation of boxers in the family. They taught me everything I know. When I was small, we all were fans of boxing; they started training when they were 10 years old and started boxing amateur at 17. Now both of them have more than 60 fights. When I was small, I always watched them fight and always liked it. I made my amateur debut when I was 20 years old, but I helped my brothers box when I was 15 and I think that boxing was in me and now, I have 30 pro fights with a very good record.”

In September 2010 at the Arena Solidaridad, in Monterrey, Nuevo León, Mexico, Ruiz beat veteran Jesús Vázquez to win the WBC Continental Americas super flyweight championship.

Ruiz won the title on January 22, 2011, by a ninth-round technical decision over Nicaraguan Álvaro Pérez and made four successful title defenses.
