with kettlebells of varying weights.

‘This got Chris down to his fighting weight of 220lb [100kg] – and as you can see from the pictures, it was all muscle.’ Hemsworth adds that he kept a ‘very close eye’ on his diet. ‘I was eating a lot of clean protein, fruit, vegetables and some carbs, as well as drinking four to five litres of water a day.’
