Christian Bale is Hollywood's ultimate chameleon. The actor has famously molded his physique for roles, from a sculpted Patrick Bateman in American Psycho (2000) to a skeletal Trevor Reznik in The Machinist (2004). But his methods for these extreme transformations are as intense as his performances.

Christian Bale’s Workout

Before American Psycho, Christian Bale had never worked out seriously, but his determination to beat Leonardo DiCaprio for the role pushed him to get into the best shape of his life.

“After every day, he would go work out for hours and hours and hours to get into that incredible shape,” said Matt Ross, Bale’s co-actor.

For the role, Bale followed a heavy-lifting approach. According to Chris Antoni, founder of Tailor Made Fitness, Bale’s workout likely looked something like this:

• Bench press – muscles worked: Pecs, Triceps, Front Deltoids
• Squats – muscles worked: Quadriceps, Hamstrings, Glutes, and Core
• Deadlifts – muscles worked: Quadriceps, lats, Erector Spinae, Glutes, and Hamstrings
• Shoulder press – muscles worked: Deltoids, Triceps
• Pull-ups – muscles worked: Lats, Trapezius, Biceps, and Forearms

“To maximise muscle hypertrophy, add in more accessory movements such as tricep pushdowns, bicep/hammer curls, leg extensions, and hamstring curls,” says Antoni.

Antoni also expressed that HIIT workouts were the best approach to achieve defined abs. However, American Psycho was just the beginning.

Christian Bale Kept Pulling off extreme transformations

Four years after American Psycho, Christian Bale once again faced a herculean task when he took on the role of Trevor Reznik in The Machinist.

Bale shed around 60–63 pounds (27–29 kg) for the role, following a brutal black coffee fast in which he reportedly consumed only black coffee, one apple, and a tin of tuna per day.

According to health expert Daniel O’Shaughnessy, “this is less than 200 calories per day, so it’s not healthy at all.” Soon after The Machinist, Bale started hitting the gym once again, bulking up for Batman Begins (2005).

However, he went a bit overboard while trying to add muscle for his role. “I overdid it because I was enjoying gorging. I was ignoring advice about taking it slowly. I was straight into pizza and ice-cream and eating five meals in a sitting,” said Bale in his conversation with HuffPost in 2017.

While Bale is no longer taking up roles that require such drastic transformations, his impressive dedication to achieving the look each character required remains a benchmark today.
