The current president is Fernando Yécora, who succeeded Horacio Raúl Ulloa after 20 years as head of the institution.

Gimansia made its debut in the AFA Torneo Nacional versus Boca Juniors at La Bombonera, where they lost 3–1.

The team took part in the first edition of the B Nacional, the 1986–87 season, achieving promotion from the Torneo del Interior by beating rivals Talleres de Perico on penalties after a 1–1 draw over 90 minutes.

In the 2004 Apertura with Francisco Ferraro as head coach it finished fourth, and with Roberto Carlos Mario Gomez in the Clausura 2005 GEJ finished first in the league and in the aggregate table as well, but in the promotion playoff with Tiro Federal they lost, which meant they wouldn't become league champions and had to play another playoff.

The second playoff was against powerhouse Huracán, and Gimnasia narrowly won on aggregate 1–0 to achieve promotion into the top tier.

In the Clausura 2006 Gimnasia had an excellent campaign and achieved another fourth place finish in a championship where it was the revelation club.

Located in the Luján neighborhood, it has a capacity for 23,000 spectators and the playing field dimensions are 105 by 78 meters, being in 2nd place behind Estadio Monumental José Fierro (#1 in 33,000) of the largest stadiums in northwestern Argentina.
