The boys of One Direction were born with otherworldly good looks, but keeping in shape still takes some work!
That’s why trainer Mark Jarvis has been working with them for the group’s North American tour!
As you can see from the pics, he’s got Liam Payne using the TRX equipment, Harry Styles boxing, Niall Horan pumping iron and Zayn Malik working out his cheekbones in pictures.
Louis Tomlinson is conspicuously missing from the pics, but maybe he’s just camera shy.
Or his workouts are so intense that Twitter can’t handle the awesomeness!
Yeah, that’s probably what it is! LOLz!
Take a peek at the 1D guys getting sweaty (below)!
