Arnold Schwarzenegger put some muscle into this world-record weightlifting attempt.

Ah-nuld himself was on hand to watch Eddie Hall set a record by deadlifting 1,018 pounds at the Arnold Classic Australia. Not only was the Terminator in attendance, but he also helped spur on Hall's run into history by cheering him on.

Arnold seems really into Hall's effort. It looks sincere, right? Because if it's not, then that's the best acting job he's done since Twins.

After the 27-year-old Hall, who's nicknamed Beast, finished, he exchanged some pleasantries with Schwarzenegger, who then went on to congratulate Hall while addressing the crowd. He also shared the moment on Facebook.
