The One Direction hunk is determined to get in shape before the end of the band's 'Take Me Home' world tour - which concludes in Melbourne, Australia, in October - so his personal trainer has been encouraging him to submerge himself in ice-cold water after exercising in order to tone up.
"The ice baths are not pleasant but it means his strained muscles will recover quicker. It won't be long before he's got the body of an athlete."
The 19-year-old singer has signed up for two grueling workout sessions a day in a bid to get the same body as Brad Pitt, often exercising at 2am.
It was recently reported the 'Kiss You' hitmakers had been put on a strict fitness regime and healthy eating plan by their record label Columbia because of their junk food addiction and habit of lounging around playing video games.
The band have been whipped into shape for their tour thanks to a combination of circuit training, low-carb diets and boxing.
