Firas Zahabi is a world-renowned MMA coach. He has trained the likes of former UFC welterweight and middleweight champion Georges St-Pierre, former Bellator welterweight titleholder Rory MacDonald and former WEC bantamweight champ Miguel Torres. Zahabi is a Brazilian jiu-jitsu black belt and trainer as well.

Meanwhile, Devon Larratt is the No.1-ranked arm-wrestler in North America and is considered one of the greatest of all time. He currently holds the right-hand legacy hammer, which is a symbolic representation of the world's best arm-wrestler. Larratt has also previously held the left-handed legacy hammer in the past.

Devon Larratt was trained by Firas Zahabi for his exhibition boxing debut against Hafthor Bjornsson

Hafthor Bjornsson, who is known for playing the role of Gregor 'The Mountain' Clegane on the HBO series Game of Thrones, was scheduled to take on fellow strongman Eddie Hall in an exhibition boxing matchup last month. Bjornsson was the 2018 World's Strongest Man, while Hall achieved the accolade the year prior.

Hall suffered a torn bicep and had to withdraw from the bout. Devon Larratt stepped in a month before the encounter to face Bjornsson.

Larratt trained at fellow Canadian Firas Zahabi's Tristar Gym in Quebec to get himself ready for his boxing debut.

Despite that, Hafthor Bjornsson defeated Devon Larratt via TKO in the first of six three-minute rounds in Dubai, UAE, on September 18.

'No Limits' is set to return to arm-wrestling by putting his legacy hammer on the line against John Brzenk in December. The former retired Brzenk holds a 3-1 win-loss record over his upcoming opponent.
