Liam Hemsworth showed up at a Los Angeles fitness center on Monday afternoon (April 15).

The handsome Aussie actor gave the shutterbugs a look at his beefy arms thanks to his white tank top which he paired with black shorts and colorful cross trainers.

On Sunday night, Liam attended the 2013 MTV Movie Awards without the support of his fiancé Miley Cyrus, further adding fuel to the fire that their relationship has fizzled.

Even the “Hannah Montana” gal’s father Billy Ray Cyrus is unsure of his daughter’s marriage plans- he told press, “I don't know. I know as I was writing a book, I wanted to keep that particular moment [Miley’s wedding] as open-ended as possible. I didn’t know the answer."

“They're young, they're kids, the great news is they’re great friends, they're really good friends. I play it by ear, I know what ever's meant to be that's the way it's going to happen.”
