Bodybuilding superstar Shawn Rhoden -- the reigning Mr. Olympia -- just turned himself in to authorities in Utah and pled not guilty to multiple felony rape charges, TMZ Sports has learned.
As we previously reported, Rhoden -- who goes by Flexatron -- is accused of raping a female bodybuilder during a hotel encounter back in Oct. 2018.
According to court docs, Rhoden's accuser claims Rhoden forced himself on her inside his hotel room - and despite repeated pleas to stop, he refused. She claims he eventually stopped and let her leave the room.
