Kellan Lutz: Shirtless Workout & 'Arena' Trailer!

Kellan Lutz shows off his ripped muscles as he goes shirtless for a workout on Wednesday (August 3) at the beach in Los Angeles.

The 26-year-old actor went for a jog along the boardwalk and used the rings to keep his body in shape.

The trailer for Kellan‘s upcoming movie Arena was recently released! The film, which also stars Nina Dobrev and Samuel L. Jackson, is about a man (Lutz), who finds himself forced into the savage world of a modern gladiatorial arena, where men fight to the death for the entertainment of the online masses.
