In her chat with The Sun, Sweeney also credited costar Katy O’Brian, 36 – who portrays fellow boxer Lisa Holewyne – for her strength and resilience.

‘Katy is a badass,’ Sweeney said. ‘I mean, she is strong. Katy’s only request was, “Please don’t break my nose.”‘

The interview with Sweeney also detailed her intense training regimen for the role of the athlete, which has already generated early Oscar buzz.

‘I built my own Rocky gym in my grandma’s shed and I trained back home in Idaho,’ said Sweeney. 

Sweeney said she ‘put on 35 pounds during’ a three-month span in which she exercised frequently and consumed protein shakes.

Said Sweeney: ‘I worked with my weight trainer in the morning and night, and then I had a boxing coach I worked with every day for two to three hours.’

Martin, who was Don King’s first-ever female client, gained national spotlight in March of 1996 when she captured the World Boxing Council women’s lightweight championship in a bloody Las Vegas bout against Deirdre Gogarty.

Martin, who was nicknamed The Coalminer’s Daughter, was on the undercard of the infamous 1997 bout in which Mike Tyson bit the ear of Evander Holyfield.
