And it sounds like Sir Tom wants to make sure he’s looking healthier than ever, going on walks and cutting back on the drink.
Sir Tom told The Sun newspaper today: “I do a fast walk. I used to run, but my right knee has been a problem. Now I do an hour on the cross trainer in the gym, which is just the same.
“I try to work out when I can. It’s important to look after your health. You want to look well, so I watch what I eat and I try not to drink too much alcohol.”
Sir Tom admitted that the show needed to sort a few things out in its format, telling the newspaper: “This time we have things we need to iron out.”
BBC One boss Danny Cohen previously said that he hoped Jessie J, Sir Tom Jones, Will.i.am and Danny O’Donoghue would all return next year.
“We thought they made a very big impact for a first series and we want them all to come back,” he said last month. “We haven’t signed any contracts yet, so I can’t say anything official. But we said at the end of the first series that we wanted all of our coaches to come back.”
The Beeb chief also revealed plans for “dramatic changes” for series two, including less live shows and more audition rounds.
“Those live shows, the audience became over familiar with the grammar,” explained the channel controller. “It still works on Strictly and The X Factor, but audiences became over familiar with it.
“It’s not rocket science to say that the Blind Auditions were the best bit of the series.”
The Voice UK will return to BBC One in the new year.
