The British ace will work alongside fitness coach Yutaka Nakamura in 2025 and hopes that teaming up with a man who has helped Maria Sharapova and Naomi Osaka can end the injury problems that have dogged her career so far.
Raducanu said: "I need a more tailored approach and someone dedicated to me.
"My athleticism is a big strength I have nowhere near fulfilled, I think I can become one of the best athletes in tennis.
"Yutaka adds another dimension to the way Nick [Cavaday] and I work, it has become integrated and connected… we can already see things that we do in the gym transferring onto the tennis court.
"We’re on a journey of exploration."
Raducanu is proud of the way she has rebuilt in 2024 to be ranked inside the world's top 60 after she had missed much of last year after having surgery on both wrists and her left ankle.
The former US Open champion told BBC Sport: "Sometimes I need reminding: I’m top 60 and I’ve played less than 15 events, which is pretty unheard of.
"I have to pat myself on the back for that."
Raducanu knows she is a "dangerous" player for others to face and is hoping to go further in tournaments next year.
She said: "I know I’m a dangerous player [and] I know no one wants to pull my name in the draw.
"I take pride in that and I’m looking forward to hopefully staying on court longer next year."
