I'll let you in on a secret. As a fitness editor, there is nothing I love more than examining the workout routines of Hollywood's richest and most famous people. Whether it's finding the exact routine Chris Hemsworth did on the set of "Thor" or Carrie Underwood's favorite leg workout, I love trying out the workout routines of some of the most famous faces in the world.

With that in mind, I did a little research to find out why so many people are Googling "Kendall Jenner abs workout." Fortunately, that wasn't too difficult. Jenner has published an 11-minute abdominal workout that he does when he feels guilty about sitting around watching TV (which is relatable). On her site and app, which is now closed, Jenner shared the workout. Sometimes when I'm watching TV, I think, 'I should be doing crunches or sit-ups right now. Then I get off the couch and do it.' Read on to see what happened when I did the same thing.

Remember, what works for Jenner may not necessarily work for you or your body. If you are resuming exercise after an injury or pregnancy, it is worth checking with your doctor or personal trainer before starting a new exercise routine. Also, visible abdominal muscles means that your body fat percentage is low. Body fat percentage can be achieved not only by doing crunches in the gym, but also by balanced exercise, nutrition, and sleep. Here is how to calculate body fat percentage and why it is important.

Ready to get in a workout? Here's Kendall Jenner's ab routine:

Forearm plank: 30 seconds

For the forearm plank, get into a press-up position with your arms slightly wider than shoulder width. Here, tighten and hold the abs and glutes.

High plank: 30 seconds

For the high plank, begin in a press-up position with arms slightly wider than shoulder-width apart and weight on the floor with both hands on the floor. Think of a straight line from the heels to the top of the head to strengthen the core.

Side plank: 15 seconds each side

Straighten one side and stack the legs. Place your forearms on the floor so that your elbows and shoulders are in a straight line. Engage the abdominal muscles and raise the hips and knees off the floor so that the legs are in a straight line from head to foot. Only the forearms and feet should touch the ground. Do not allow the hips to fall, and look straight ahead during this time.

Side Plank with Crunch: 5 reps each side

In this exercise, from the side plank position, crunch the upper knee and upper elbow together.

Single arm/leg plank: 15 seconds

Similar to the Bird Dog exercise, start in a high plank position, lift either the right or left leg a few inches off the ground and extend the opposite arm forward. Pause here, then return to the original position and switch sides.

Rocking plank: 15 seconds

For the rocking plank, begin in a forearm plank position with weight on the elbows and rock your body forward until you are on your toes. Then slowly return to the original position. Repeat this back-and-forth motion. [33] [34] Knee-to-elbow plank: 5 times each side [35] [36] Start in the high or low plank, whichever is easier, and bend the left leg to touch the left elbow, then extend it back to the starting position, and repeat. after 5 repetitions, switch sides.

Crunches: 20

To perform crunches, first lie on your back with your lower back on the floor. Place your hands on either side of your head, tighten your abdominal muscles, and crunch your torso toward your knees. Return to the starting position and repeat.

Bicycle Crunches: 30 seconds

To perform a bicycle crunch, lie on the floor with your back to the ground. Place your hands next to your head and lift your shoulders off the ground. Bend your knees and pull your legs up off the ground. While straightening your left leg, bring your right knee close to your chest and twist your body so that your left elbow touches your right knee when your right knee rises. Do the same on the other side, making sure the leg and shoulder are off the ground.

Vertical Crunch: 20 seconds

To perform a vertical crunch, lift both legs toward the ceiling and keep them as straight as possible. Engage your torso and crunch your torso toward your legs, keeping your arms outstretched and your toes attached.

Frog Crunches: 15 times

For frog crunches, lie on your back, keep your legs together, drop your knees to the side, and form a diamond shape with your feet. Crunch upward from the abdominals to the torso, arms extended between the legs.

Leg lifts: 15 per leg

Lie on your back and extend both legs over the mat. Raise your head and neck off the mat, lift one leg toward the ceiling, and slowly lower it back down to its original position. If too much pressure is placed on the lower back, place both hands in a diamond shape on the small of the back.

This workout looks short and simple, but don't be fooled, as it works all the different parts of the core and burns up in no time. I did this workout after a week of daily abdominal training with Pamela Reiff, so by the end of the first 30-second plank, I could already feel my core burning. [22] [23] Speaking of planks, the first half of this workout focuses on planks, progressing to forearm planks, high planks, side planks, and then adding crunches and knee tucks. You don't have to hold the plank for a long time to get the benefits, but the intervals are short, so it's important to keep your form tight. I was conscious of making sure that my navel sucked into my spine and that I kept a straight line from my heels to the top of my head. In the rocking plank and the knee-to-elbow plank, the added movement in the plank forced me to work harder to keep my torso stable throughout.

From the plank, I moved on to various forms of crunches. If you suffer from lower back pain, as I do, it is important to keep your spine firmly planted on the exercise mat when doing sit-ups. If you find that your back bends over, try to lower your range of motion to avoid putting extra strain on your spine. Crunches, bicycle crunches, and toe-touch crunches all hit the rectus abdominis or "six-pack" muscles on the front of the trunk.

The last two exercises, frog crunches and leg lifts, both feel quite Pilates-inspired, and the model has been spotted attending Reformer Pilates classes in Los Angeles with her friend Hailey Bieber. Here's everything you need to know about Pilates and weight loss and eight of the best Pilates exercises that target your core for the ultimate burn. The leg lifts in particular worked the lower part of my abdominal muscles and made me feel like I had worked out all the different parts of my midsection.

Of course, no workout will give you instant results, but I felt like I worked my abs in a short amount of time while watching TV. There is no doubt that Jenner is working hard to stay in shape and making exercise a priority, but this workout proves that you don't need to spend hours in the gym to work on your core.
