Pešta is a Gladiator Championship Fighting Heavyweight Champion and he competed in the Heavyweight division of the Ultimate Fighting Championship. He became historically the second UFC fighter from the Czech Republic, after Karlos Vemola.
Mixed martial arts career
In 2006, Pešta started training Traditional Musado under the leadership of Vít Skalník. Traditional Musado is the civilian version of Musado, the close quarters combat system used by the Military of the Czech Republic. In 2008, he started training MMA under the leadership of Jiří Vesecký in the gym in Příbram, Bohemia.
Pešta moved to Prague to study at university and to pursue MMA career. In Prague, he began training in Penta Gym. He began amateur fighting at age of 18 and made his professional MMA debut in 2010.
His last fight in GCF was with longtime GCF Heavyweight Champion Lukáš Ťupa for the GFC Heavyweight Championship on December 7, 2013 at GCF 26: Fight Night. Pešta won in the first round by his signature move, strikes from the (side) mounted crucifix position and he became the new GCF Heavyweight Champion and #1 in Czech heavyweight rankings.
Ultimate Fighting Championship
Pešta was expected to face Damian Grabowski on January 15, 2017 at UFC Fight Night 103. However, Grabowski pulled out of the fight in late December for undisclosed reasons and was replaced by Alexey Oleynik.  He lost the fight via submission in the first round.
In May 2017, Pešta was released from the company.
Fight Nights Global
He signed a contract with Fight Nights Global in the second part of year 2017 after one match at home organization XFN.
Pešta's signature move, the (side) mounted crucifix position, was nicknamed/called "Bába pod kořenem (English: The crone under the root)" by his fans, after the famous Czech TV Nova's report about an elderly woman who gets stuck for 11 hours under the root of a tree overnight, 50 meters away from her rented hut in the forest and her friends.
