After starting off her day with a beverage, Jenner changed into a black sports bra and a matching pair of leggings, which she paired with a plain baseball cap and a pair of white sneakers. To begin her workout, the mother of one went outside, making her way up a steep incline before going for a run. Then she headed back inside to continue her workout on the treadmill, opting for a 12 percent incline — which mirrors the experience of a steep hill, according to The Washington Post — at a 3.2 pace.

While wearing a waist trimmer, a Velcro-fastened belt that some people think increases calorie burn, the Kylie Cosmetics founder opted for a series of core-strengthening moves, including toe touches and planks. Showing off the fruits of her labor, Jenner ended the video by showing off her toned abs."Never miss a monday," she captioned the clip. Over the weekend, the reality star also documented her post-workout achievement. "Cute little Sunday," she wrote on her Instagram Story alongside a screenshot of a fitness tracker which showed she had logged 3.5 miles of walking and running that day. As for her diet, Jenner also shared that she's "really trying not to eat meat rn," posting a video on her Instagram Stories of her "little dinner" of grains, broccoli and sweet potato.

In an episode of Harper's Bazaar's Food Diaries YouTube series, the beauty mogul said that keeping a pre-sliced apple by her bed at night can be surprisingly helpful. "I turn on my TV, I get really comfortable, and I pre-slice an apple by my bed," she shared at the end of the video. "Since I'm really comfortable I'll be too lazy probably to go down to the kitchen, so my only choice is this apple. So that is how I swerve my late-night cravings."
