Hafthor Bjornsson has broken another world record at the 2015 Arnold Sports Festival.

The 6'9" 419-pound powerlifter from Iceland, who plays the role of Ser Gregor "The Mountain" Clegane on "Game of Thrones" on HBO, was at the 2015 Arnold Strongman Classic. It has only been less than a month since he broke a world record that stood for an entire millennia at the World's Strongest Viking competition. In that contest in February, Bjornsson lifted a log 30 feet long and weighing 1,433 pounds on his back. GulfLive reported that he took five steps with the huge log.

IGN.com reported that during the Arnold Sports Festival weekend, he set another world record by tossing a 56-pound kettle bell 19 feet and three inches into the air, using only one arm.

He resorted to Instagram to share videos of his heroic feat and stated his experience over the weekend. He wrote, "I had ups & downs at the Arnold Strongman Classic this past weekend. I did an awful mistake in the deadlift which cost me a lot of points! Yesterday made me feel a little bit better though. I did a weight for height event on the main stage. I went over 19'3 with a 56lbs weight and that is a New World Record!!"

It was followed by another video which he said "provides a better angle of the World Record at 19'3."

"Game of Thrones" Season 5 is set to launch in 2015 and fans are already excited to know what would become of Gregor Clegane after he acquired a fatal blow in his last duel against the Red Viper. In his last scene, Clegane was being treated in a room from the venom that could potentially kill him. Cersei Lannister advised the physician to do everything in his power to cure The Mountain.

International Business Times reported in September 2014 that it has not been confirmed yet whether Clegane will make an appearance in Season 5. Bjornsson was reportedly spotted in Belfast, one of the filming locations for the TV show. The actor and strongman allegedly stayed in the city for a few days.

In the books, the people of Dorne were enraged upon discovering that Clegane brutally murdered their prince, Oberyn Martell, during the duel. The Lannisters had to send the severed head of Clegane to appease the citizens of Dorne but some suspected that the head was not Clegane's. In the meantime, Cersei Lannister had a new knight for hire who never takes his helmet off and took a vow of silence. He was the same size as The Mountain, so it is possible that Bjornsson might have a new role in the series.
