Ever wondered how the most catwalk-friendly of the Kardashian/Jenner clan keeps her abs in check?

Kendall Jenner has been sharing her fitness secrets on her app and it turns out that she spends just 11 minutes per day working on that killer bod. Her trick, aside from super-human genes? A carefully choreographed collection of moves designed to firm and tone the core, apparently. The good news is you don't need any special equipment to do these at home, making them ideal for a jet-setting multi-millionaire's lifestyle and also quite handy for anyone who can't afford a gym membership. The bad news? Be warned: almost every one of these exercises will make you want to lie on the floor in the foetal position and order a pizza. Keep it up however, and you'll be rocking a washboard tummy by the time your summer holiday comes around. Probably. Hey... if it works for Kendall. THE WORKOUT  1. Forearm plank, 30 seconds 2.
