Take it from experience. In a scene from the movie, in theatres now, Powell gets thrown against the wall by the veteran actor who's trying to talk some sense into the young star.

"The dude is like in his 60's and he knocks the breath out of me in one throw," Powell admitted.

But in defense of Powell, the young actor is still a stud. In order to get in crazy good shape for the film, Powell stuck to a crazy diet and workout routine. "I would go to catering and ask them for chicken, Brussel sprouts, spinach and that will just get you wash boardy," he told E! News.  "Then when you work out with Stallone your set."

And despite tough workouts and some intimidating costars, Powell (who is single, ladies) can't wait for the next installment.

"Yes, you can expect to see me [in Expendables 4]," he told E! News. "I will be getting ready to shoot it soon."
