With a height of 6ft 1in, a ballerina's physique and a schedule that fits in high intensity interval training as well as classes at New York University and a full-time career as a supermodel, it's no surprise Karlie Kloss approaches her health and fitness regime like an Olympic athlete.
In an interview with The Sunday Times, the St Louis-born model admits: 'Even if I'm not an Olympian in Rio right now, I treat myself as an athlete in my daily life.
'I challenge myself, try new things in my strength training and cardio. I try to be the best I can, whether it's my fitness routine or how I think about food and nutrition,' she added.
But how exactly does one find time to train like an athlete while trying to keep down a 9-5 job, a social life and, well, sleep?
According to ELLE's Tech Trailblazer cover star, you just need to set aside five to seven hours a week of exercise into your schedule which is 'totally doable'.
Oh Karlie, and it was going so well… *Throws running shoes back in rucksack*
All jokes aside, such steely professionalism is necessary when you're earning approximately £4 million a year modeling for fashion brand campaigns, such as Stella McCartney's new range of Adidas sports kit.
But for Karlie, it's not so much about her appearance as it is feeling strong that is of higher priority.
'I want to feel strong. That's when I feel best.
'I always say the hardest part is putting your gym clothes on. But no matter how long and exhausting your travel or your work was, if you can get yourself there and give it whatever you've got, it will be worth it. You will feel better afterwards,' she added.
It's good to know we're not the only ones that struggle to wriggle into a sports bra.
