Louise Redknapp was secretly in agony during her time on Strictly Come Dancing.
The former Eternal singer impressed fans of the show with her performances this series.
But she was so bruised from her gruelling training sessions and rehearsals that she was forced to have regular physio sessions.
Louise worked hard on her dances with her professional partner Kevin Clifton.
But she struggled as the series went on due to the pressure her body was under.
She told the Daily Star Sunday: “It got very tough but I just gave it my best to see what happened.
“But my body definitely got tired. My calves have been in bits. I had lots of baths and had physio. That helped.”
However, there is an upside to all her hard work - taking part in the BBC ballroom dance contest has made her body more toned.
She said: “I’m definitely feeling fitter. It’s good to get back out there and be active and do something I enjoy doing.”
