Sofia Richie once spent an hour in the gym just lying on the floor.
The 19-year-old model – who is dating Scott Disick – admitted she isn’t "disciplined" about working out, so prefers to take classes where she has someone "yelling" at her, rather than motivating herself to exercise in the gym.
Speaking to HELLO! Fashion Monthly, she said: "This morning I went to the gym and just lay on the floor like a starfish for an hour.
"I’m kind of bad at working out on my own. I’m not disciplined to run a mile, so I usually have to take a class.
"I SoulCycle a lot and do Barry’s Bootcamp – I need someone yelling at me."
The blonde beauty also admitted her trademark slicked-back hair style is more to do with her always having nourishing treatments on her tresses, rather than being a particular fan of the casual up do.
She said: "I don’t know if you keep up to date with my day-to-day life, but I always wear my hair in a slicked-back bun.
"People just think I like the hairstyle – I do, but I’m really just trying to keep it all together.
"I usually have coconut oil all over my hair or a leave-in conditioner."
When it comes to make-up, Sofia tries to keep her look as "light" as possible.
She said: "I keep it really light with my make-up. Whenever I cake it on, I get these little spots.
"I use Nip + Fab foundation, then an eyebrow pencil and I contour. Not a full countour; I use a Giorgio Armani powder."
The jet-setting starlet also admitted she is always prepared for travel and is never without her passport.
She said: "I always carry my passport in my handbag – which I know you’re not supposed to do."
