Little Mix have launched themselves into a vigorous exercise regime following their X Factor win, according to reports.
Jesy Nelson, 20, who was taunted online about her weight while on the show, has now enlisted a personal trainer, the Daily Mirror reports.
She said: "I got a personal trainer, then we all got one. We need to get fit for the tour.
"We're doing six songs and they're all really upbeat, and they all have a bit of dancing in them, so we really need to get in shape.
"Me and Leigh-Anne (Pinnock) are even going for a good, long walk every morning along the pier."
The band are preparing for their tour, which launches at the end of February, and recording their debut album in Brighton.
Perrie Edwards joked: "We'll do a few warm-up routines then end up nearly having a heart attack when we're on stage."
