Some say the stamina required of a model on set is a marathon, not a sprint. After shadowing Kendall Jenner behind the scenes on a daylong shoot, we notice that the recent Vogue cover girl is not the type to just sit around and be tended to; rather, we see her getting in on the action with everything from wardrobe to photography and even a bit of ab work. (Those six packs don’t tone themselves.) All in all, it looks like a fun and gorgeous, albeit exhausting, day. Watch for yourself to see how Kendall makes it work, then shop the products she’s wearing below.
