The One Direction boys left little to the imagination during their live stream on 1D Day. Harry, Liam, Zayn, Niall and Louis gave their fans seven straight hours of One Direction, and it included showing some skin. In one video, the boys show off how they get their fit bodies. They show off their work out routine which includes pumping iron, boxing and a lot of cardio. When discussing his health regimen, Harry said "It's currently 12:15am. I train for an hour, then go to sleep for four hours. Get up again at 5am, have breakfast and go to bikram yoga and have an espresso afterwards. Easy peasy"
