In 2023, he was unveiled as Nitro in Gladiators, and took part in last year's Strictly Come Dancing Christmas Special partnered with Nancy Xu.
Aikines-Aryeetey said the Christmas Special "was so nice I just had to do it twice".
On Monday, he appeared live in the Newsround studio disguised as "world-famous choreographer Nicky Trott", there to talk about a scientific study into the benefits of dancing every day.
He then revealed his real identity and told viewers how excited he was to be joining the dancing competition.
"I'll be bringing tons of energy to light up the dance floor," he said. "Let's hope I'm as quick picking up the routines as I am on the track."
The next three celebrity contestants joining the new series of Strictly will be announced on The One Show on Monday evening.
Two new professional dancers are also joining the line-up this year - Alexis Warr, who won US dance series So You Think You Can Dance in 2022, and Australian-born Julian Caillon, who has appeared as a professional dancer on three seasons of Australia's Dancing With The Stars.
