With his starring role as a naval detective in the 2009 TV series NCIS: Los Angeles, Chris O'Donnell has finally consigned Batman's sidekick Robin – a role he played in two 1990s films – to history, and he's glad to be moving on. "I had a lot thrown at me early on," admits the 39-year-old now. "It was overwhelming."
One legacy of his time as the Boy Wonder was a bad back, thanks to a herniated disc caused by a stunt that went wrong. The injury and the demands of various roles during his career meant that his weight has fluctuated over the years – but starring alongside rapper/actor LL Cool J in NCIS encouraged him to get back to his best. "His arms are insane – they're as hard as a wall," he says. "I'm just an average guy trying to keep my body in good condition so I can still do the things that I love. I don't want to give up sports. I want to move around with my kids and play football in the backyard. [But] I'm about to turn 40 and I have to work hard to stay fit."
Help came in the form of fitness coach James Bolden. "It was easy training Chris because he is a natural athlete and very good at listening to advice," Bolden says. "If he had decided to become an athlete instead of an actor he would have done very well. His training as an actor enables him to focus on the task at hand."

Bolden believes that anyone can make significant improvements to their body, no matter what shape they're in. "My training philosophy is consistency and simplicity," he says. "Everyone wants to know the secret of losing fat and adding muscle. It's simple: go to the gym, do push and pull exercises, eat clean, sleep deep and avoid unnecessary stress, and you're good to go."

Here's O'Donnell's full workout.
