Presenter Helen Skelton said she felt like she had "been in a car crash" after training for her Celebrity Boxing Sport Relief challenge.
The 34-year-old will go head-to-head with Love Island's Camilla Thurlow and admitted she is just hoping she does not end up with a broken jaw.
She said of getting ready for the ring: "I thought I was relatively fit, but I was wrong. Boxing is really hard.
"I felt like I'd been in a car crash for three days – I could hardly move.
"The hardest part is thinking someone is going to punch you in the face or the stomach. The training I've been doing is just hitting someone with pads on, so they're not hitting you back.
I felt like I'd been in a car crash for three days – I could hardly move.
"And then the other day my husband just shadow boxed me and I was like, 'What are you doing?' And he said, 'Well that's what's going to happen'.
"I've never been in a fight in my entire life. I'm definitely not a fighter – I'm a lover."
"I just want to not get a broken jaw," she said.
Helen wants the females to put on as good a show as the male contestants.
"We all bang on about everything being equal, I don't want people to watch it and be like 'Oh you're a girl fighting…'" she said.
"I just want the girls to put on a good show and as much of an entertaining boxing match as the boys, because I know we're laughing about it and doing it tongue-in-cheek and all the rest of it and it's for Sport Relief and it's for fun, but actually let's give credit where it's due."
