Jonathan Majors Hits Gym Hard For Potential New Film Role

Jonathan Majors' Hollywood career isn't over yet -- even as his sentencing looms, he's going full gym rat, getting in shape for an upcoming film shoot ... and we got a glimpse of his routine.

Sources close to Majors tell TMZ … he was in L.A. for a week, hitting the gym hard and training for a possible gig before flying back to New York.

No word on what Jonathan's potential role might be, but we're told it would require him to be in incredible shape ... and that's why he was training so intensely.

Our sources say Jonathan's aiming to get shredded -- like superhero ripped -- and the video shows he's getting pretty close to that goal.

Remember, Jonathan was a Marvel star before the studio dropped him immediately after a New York jury found him guilty of misdemeanor assault and harassment for the now-infamous incident with his ex-GF, Grace Jabbari.

We're told Jonathan's working out with his regular trainers, who are getting him in tip-top shape.

For the next month or so, our sources say Jonathan will be shuffling back and forth between visiting Meagan Good in New York and training in Los Angeles.

What's unclear is when the movie shoot would begin -- if he lands it, time is of the essence ... assuming he'd have to get it done before he's sentenced.
