Entram Gym

Entram Gym is a mixed martial arts and Brazilian jiu-jitsu gym in Tijuana, Baja California. It opened in 2006, founded by Raúl Arvizu. In the two decades since, the room has figured in reporting on the city's fight scene for two connected reasons: the fighters it developed from its own classes, and the fighters who later moved to Tijuana to train inside it.

A grappling foundation

The gym's founder, Raúl Arvizu, holds a Brazilian jiu-jitsu black belt under the American grappler Dean Lister. That black-belt lineage set a defined grappling standard for the gym from its early years, in a period when the local sport was still taking shape.

From the youth classes

Entram runs a youth program alongside its adult training, and the route from a beginners' class toward competition is part of how the gym is described in coverage of the Tijuana scene. The clearest recent evidence of that route is not a roster name but an event: for LAP 05 on 3 May 2026, the gym's promotion hosted more than fifty guests from the Orfanatorio Puerta de Fe, and one of them competed on the card. Arvizu has stated plans for a free youth mixed martial arts school in Tijuana in the promotion's second phase.

A city that had long exported its fighters found, in one room, a reason for fighters to arrive.

The arrivals

The gym's profile widened beyond the fighters it raised. By early 2022, Entram reported more than fifty fighters from across South America training at the gym. ESPN Deportes has described Entram as one of the most recognized mixed martial arts gyms in Mexico. A gym that had once sent its own athletes outward was now a place other athletes relocated to reach.

Taken together, the locally developed fighters and the incoming ones account for much of the attention Entram draws in reporting on Tijuana as a combat-sports city. For readers tracing that story, the gym connects to the coaches who run its programs, the athletes who came through it, and the amateur cards staged around it.
