Alexander Sak Biography

Alexander Sak was born in March 1992 in a small Siberian town called Zaozerniy, Russia, where he lived until 2009.

Growing up, Aleksander practiced several sports, but mostly judo and soccer, which he started as a child. Sambo was added to Sak’s activities at 17, and he quickly became a force in this sport, earning a Master of Sports title and a bronze medal at the Russian Junior Championship in 2012.

Alexander started practicing Grappling and Jiu-Jitsu by the end of 2013 as tools to help his integration into Combat Sambo, first training with friends and teammates like Vaha Aushev, who was highly influential in Sak’s development early on. He also trained with team Strela in Siberia, later joining the Jiu-Jitsu team’s headquarters in Moscow when he moved to the Russian capital in 2016, where he trained under Dmitry Selivakhin.

Dmitry Selivakhin promoted Aleksander from white to brown belt, but during this period, another black belt, Rodrigo Cabral, also gave technical assistance to team Strela and helped Alexander. The Siberian visited Cabral’s school in the United States, the Fight Factory, in search of a more competitive environment. It was there, on April 14, 2020, that Sak received his black belt from Cabral.

In 2020, Aleksander Sak moved to Germany. He initially represented Russia in a few Newaza tournaments organized by a Ju-Jutsu Federation (a non-BJJ grappling organization) and later became a representative of the German Army (2022), a contract that allowed him to become a full-time athlete. Sadly, these Newaza Ju-Jutsu tournaments coincided with most major international BJJ events, which prevented Sak from gaining notoriety. In 2024, his contract with the German Army team ended, and he became more active in the IBJJF and AJP circuits, gaining notoriety there.
