And he's only rehearsing for his first dance...
Will has been installed by the bookies as the favourite to win this year's show but in a video from rehearsals confessed he was finding the moves for his opening performance difficult.
Will, who has been partnered with pro dancer Karen Clifton, said in the clip on Facebook: "Here I am in rehearsals and it's been a long week, people.
"The dance that I'm doing is a hard dance for me.
"It could be easy for other people, for me it's a little bit like climbing a hill without any legs. Yes, it's hard work."
He added: "Karen is amazing, she is a task master."
Will has found himself being accused of having an unfair advantage due to past dance experience but he says it was "so different" to Strictly's ballroom and Latin disciplines.
The former Pop Idol winner, famous for his clashes with Simon Cowell, said previously: "Yes, I did ballet for fitness, and contemporary dance but it's so different."
The first of this year's Strictly Come Dancing live shows will air next week on BBC One in two parts, first on Friday, September 23 and then on Saturday, September 24.
The couples will be split across the two shows with six couples dancing on Friday and the remaining nine on Saturday although the line up on each show has not yet been confirmed.
