But after that? Provided they're not the esteemed Angels, it appears that it's up to them - and Kendall Jenner has opted to not work out vigorously. In fact, she hasn't worked out at all, PeopleStyle reports.
"I've been really, really bad and I literally haven't worked out once since the Victoria Secret show in November," she said to PeopleStyle.
That's well over four months without a formal workout.
She told PeopleStyle how leading up to the Fashion Show she "worked out so hard for that, like, literally every single day - sometimes twice."
But now, she's completely changed gears.
"I was really on point, and I haven't been eating the same. Like I've been eating just s- all the time. 'Cause I feel like I'm on vacation now for the past couple months," she said.

Her apparent reason for forgoing exercise is similar to an excuse many of us might give: she's too busy.
PeopleStyle points to a laundry list of things she's had going on recently, such as various fashion shows and launching an Estee Lauder eye shadow palette. (She's also spent some time working for a competitor underwear brand, Calvin Klein.)
Victoria's Secret models - genetically blessed as they may be - are just like many of us: exercising for special occasions, and then resorting to their old habits.
