Louis Smith's "bum cheeks" are very sore from 'Strictly Come Dancing' training.
The Olympic medal-winning gymnast - who has been partnered with Flavia Cacace in the celebrity dancing contest - admits the strenuous preparations for the show are already taking their toll on his body.
He said: "After the first bit of training for 'Strictly', my bum cheeks were so sore. So much pain."
The 23-year-old sportsman also admitted he is not in as good shape as he usually is because he has been relaxing since the Olympics.
He added: "I spent two weeks in Marbella after the Olympics and I haven't been in the gym for two months."
Meanwhile, fellow Olympian victoria pendleton admitted she is worried about the complex choreography that partner Brendan Cole will create.
She told Reveal magazine: "I don't know if my leg muscles will help for dancing, to be honest. I think I'm fit enough to deal with the training - the choreography will be the hard part.
"I actually woke up last night trying to remember the steps. And standing up straight will be a challenge when all you want to do is watch your feet."
