The legendary strong man Arnold Schwarzenegger is in Johannesburg, South Africa, this weekend for the Arnold Classic Africa, a multi-sport event that allows bodybuilders and amateur athletes from Africa the opportunity to participate in an international competition.

Schwarzenegger, now 71, was hit from behind by an attacker in a crowded gym, and the clip quickly went viral in social networks.

Schwarzenegger tweeted after the incident that he had not suffered damage and that "there is nothing to worry about". He also asked people on social networks to share the video of the athletes that were shown at the event instead of the video of the "guy who wants to be famous."

Schwarzenegger shared a video of a young archer taking a picture of his wheelchair, and posted an additional video on his Snapchat account.
