Mum-of-three Danielle, who admitted she was nervous to be taking part in Tom Daley's diving show, headed to the gym with footballer Jamie for a training session.
In videos shared with fans on Instagram, 30-year-old Danielle looked on at Jamie's impressive exercise moves before trying them out herself.
Captioning the video, she said: "Training session with @jamieohara24 #fit #lean #ttotal."
Working out in a grey top, black jogging bottoms and trainers, Danielle showed off her determination and upped her fitness regime as she completed some pike exercises.
Danielle, who also complimented Jamie for his "strong" physique, said: "Hardcore pikes!!! #onit." We're sure all the hard work will pay off!
For Splash!, Danielle will be trained by a team of professional coaches in a bid to perform dives from the high board.
Performing in front of a packed crowd at an Olympic size pool, Danielle and fellow celebrities will need to impress a panel of expert judges and the public as they vote for their favourites.
Each week will see a new set of celebrities and the top two celebs from the public vote will go forward to the next round.
After watching the first heat of Splash! last week, Danielle confessed to fans on Twitter: "Actually feel sick watching this #splash #nervous."
