They’re the same men you see on the cover of magazines promising ‘Big Arms Now’. But claims about LA’s biggest names getting in shape are often met with scepticism. Building muscle and burning fat for a role is their job, isn’t it? How are you meant to replicate that kind of training when you’re locked in the office for long hours and the only personal chef you have is made by Russell Hobbs?

However, it is possible to match these muscle-bound front men – all you need to do is set a training goal from the workout methods below and make them stick. Your lifestyle may not allow for 24/7 gym dedication like Dwayne Johnson. But if you make this advice – from Simon Inman, personal trainer at The Dorchester Hotel – a long-term investment, you can still see Oscar-worthy results.

Brad Pitt – Lean Muscle

OK, we’re not talking about Brad in 2016. The man has enough on his plate right now to be worrying about what he looks like with his top off. But back in 1999, Brad’s Fight Club physique set the bar for film #fitspiration, well before hashtags had even been invented.

He was strong, fast and lethal. There wasn’t an ounce of fat on his body and he was walking around with just enough muscle to fill out your favorite shirt. Not that you’d ever want to wear one if you looked like that.

Join The A-List

Legend has it that Pitt just turned up on set like that. But you’ll need to put in a little more work. To replicate this look you need to tailor your training to build muscle and burn fat at the same time. High reps and short recovery times are key to maximizing calorie burn while increasing strength.

“Stick to 60-second rest or below to get your cardiovascular system ticking over,” says Inman. “You need to make sure your body is burning oxygen without breaking down muscle – which means you don’t want to go too crazy on the weight.” If you’ve heard of HIIT training or have the chance to join a circuits class at the gym, this is the body type you’ll progress to.
