Elsa Pataky reveals husband Chris Hemsworth completely transformed her body with workout

Elsa Pataky has been rocking some serious guns of late. 

And it’s all thanks to her husband, Chris Hemsworth, who took on the role of personal trainer to knock his wife into shape ahead of her new action flick. 

Speaking to Women’s Health, the 44-year-old revealed that she lifted heavy weights over the course of four weeks under the guidance of Chris, 33, and British adventurer Ross Edgley, 35. 

‘I need to get really strong for this role, a massive change in my body – I knew I had to start [working with] heavy weights to get more muscular,’ she told the magazine. 

She went on to explain she worked with ‘big weights’ as well as ‘swimming, climbing ropes, doing burpees’ and ‘a lot of moving and acceleration.’ 

The Spanish actress added:  ‘It’s a mix of everything that really helps, and my body started to change a lot in just four weeks.’   

The stunner showed off her newly-acquired muscles as she posed with her equally buff Thor-star husband at an ’80s themed party last week, and has clearly made some serious gains. 

Elsa is gearing up for her role in Netflix‘s exciting new action drama film Interceptor.   

She will star as the lead character – a woman set to save the world from 16 nuclear missiles. 

The exciting movie will be filmed in Sydney, with production set to commence later this month.   

Elsa told News Corp last week that she has been rehearsing moves for the film using a toy pistol at home with Chris and their three children.

She said: ‘I brought home a toy gun to practice with and was showing my kids a fight I have to do and they were really excited. Especially my daughter, who has two brothers who keep telling her “we’re stronger than you” and she says “no way!”
