Sons of Anarchy's Charlie Hunnam, who flashes a big smile and even bigger biceps on the December cover of Men's Health (on newsstands now), believes in being disciplined in all aspects of life – especially his career.
"I was going to finish playing a psychopath who'd just lost his wife, and five days later I'd be on set playing Christian Grey," Hunnam, 34, says of why he famously backed out of the Fifty Shades of Grey role that eventually went to Jamie Dornan. "I was like, 'This is going to be a f---ing disaster.' "
He continues: "It was the opposite of how I've tried to ground my career, not stretch myself too thin, and always do my homework."
Although Sons of Anarchy wraps up its seventh and final season on Dec. 9, Hunnam is going to be busier than ever.

Luckily, Hunnam says he doesn't need a lot of time in the gym to stay ripped.
"I go into the gym and do 75 pull-ups, 75 dips, 150 squats, 150 pushups, and then 20 minutes of ab work," he tells the magazine. "Done. It takes an hour; I'm in and out. I sweat the whole time."
The actor adds: "I work out more for the mental than the physical aspect. I can get slightly dark when I'm not keeping a routine. It's all about feeling healthy and energetic."
