After revealing that he got nothing to hide during his recent interview, “Knights of the Roundtable: King Arthur” lead star Charlie Hunnam revealed his training routine and the things that keeps him sane. Currently filming his latest movie with Guy Ritchie, the British hunk is one of the busiest actors in Hollywood with myriads of project lining up for him.

Known for his role as Jax Teller in FX biker drama series “Sons of Anarchy,” Hunnam is letting go of leather vest and motorcycle as he moves on to play the sword wizard King Arthur. The “Sherlock Holmes” director recently shared a snap of him and the actor during the first day of filming the upcoming Arthurian film.

Sporting a fur parka and a saddlebag, the 34-year-old star kept his SOA signature scruff as he stands right beside Ritchie in the “King Arthur” set. Scheduled to be released in summer 2016, the movie features a new take on the classic English literature featuring Eric Bana (“Time Traveler’s Wife”) as King Arthur’s father, Uther Pendragon and Jude Law (“Closer”) as the villainous Vortigern.

“I tend to do whatever I think is appropriate for the character,” Hunnam told Elle Canada when asked about how he switch up his training routine to get physically fit for the role. “You’re playing the character, so go do what that character does--it’s going to bring you closer to him. For Arthur, he’s a great fighter, so I’m going to be fighting in the gym.”

He also revealed that while in between jobs he likes to work out to keep his sanity. The “Crimson Peak” star wrapped up his SOA role in December and started working with Richie in March. During his interview with Men Health magazine he admitted that he works out for his mental health rather than the physical aspect as gets “slightly dark” if he’s not keeping his daily routine in the gym.

Meanwhile, Hunnam also hinted that nudity doesn’t bother him at all and revealed that he has done full frontal when he was 18 on “Queer as Folk.” Without nothing to hide, the actor is slowly cementing his place in Hollywood as he carefully choose the next epic role to add in his acting resume.
