Fitness model Greg Plitt was killed Saturday when he was struck by a Metrolink train in Burbank, Calif. He was 37.
Plitt was perhaps best known for appearing as a cover model on many fitness magazines as well as for his appearances on the Bravo reality series Work Out.
He was struck while filming on the train tracks. It is unclear what Plitt was recording, however Burbank police told People that Plitt's death appears to be an accident, and not suicide.
Police have not commented on what footage was recorded on the camcorder Plitt was holding when he was killed, however the Bravo star had shot a number of workout videos on train tracks in the past.
Before becoming an actor, a workout guru and a fitness model, Plitt served as a U.S. Army Ranger for five years after graduating from West Point in 2000.
Plitt recently starred in an episode of Bravo's new reality series Friends to Lovers, which premiered Jan. 12. His episode was scheduled to air in the coming weeks.
Bravo producer Andy Cohen tweeted a message of condolence Sunday morning, writing: "We couldn't take our eyes off Greg Plitt after we cast him on Work Out -- was as nice as he was beautiful. Seemed invincible, like Superman."

Bravo also released a statement, saying: "This is a very sad tragedy. Our thoughts and deepest sympathy are with Greg's family and friends."
