Fitness instructor Nick Hollender said: "I make him run on the treadmill and sing all his songs without missing a note.

"He has to catch up to bandmates Gary Barlow, Mark Owen, Jason Orange and Howard Donald who have been on tour much more than him and are in

"He's not going to be left behind and wants to be trim and healthy, instead of feeling like the podgy member."
