She regularly keeps her 135 million Instagram followers abreast of her newest diet and exercise tips.
And Kourtney Kardashian was at it again on Monday when she shared some of her favorite exercise routines featuring a workout ball.
The 42-year-old former Keeping Up With The Kardashians star looked years younger than her true age a she showed off her sculpted abs while working out with her youngest sister Kylie Jenner.

Kourtney was spotted in the background of the wood-floor gym in a black sports bra and high-waisted black leggings that still showed off plenty of her toned tummy.
The 5ft1in beauty rounded out her sporty ensemble with simple black trainers, and she had her raven tresses tied back in a ponytail.
She held a basketball-sized black ball in her hands over her head, as if she was about to shoot a basket.
Kylie had her face obscured by her phone as she snapped the mirror selfie.
She had on a slightly more modest black crop top and a similar pair of black Adidas leggings.

The photo was either an old snap, or Kylie was using someone else’s phone, as she usually is seen with a newer model iPhone with more cameras.
Kourtney directed her fans to her Poosh lifestyle site for some of her favorite workout ball routines.
Most of the simple five-minute exercises were variations on yoga or Pilates moves, but performed with an exercise ball squeezed between the thighs.
Kourtney was focused on keeping her figure in tip-top shape, but late last week she let her boyfriend Travis Barker make some changes to her appearance.
Proving that she completely trusts the Blink-182 rocker, she teased on Thursday that she gave him the green light to cut her hair for her.
The reality star shared a huge chunk of her hair that had been chopped off and tagged her boyfriend in her post shared to her Instagram story, writing: ‘Haircuts by @travisbarker.’

Suggesting she handed over the scissors to the Blink 182 drummer, Kourtney kept fans guessing over her new look as she didn’t immediately share a photo of the finished result online.
However, it seems like she didn’t hold back and asked Travis to give her chop as the chunk of hair on the floor that had been cut was the length of her long ponytail.
Since getting together with Travis, Kourtney has been experimenting with her look and not only switched up her eye colour from brown to green with contacts, but has also been seen posing on social media with silver caps on her teeth.
Her recent posts have also seen Kourtney add an edge to her wardrobe, with her latest outfits seeing the star channel her inner rock chic in a sexy lace-up all-in-one.

On a recent trip to Las Vegas, Kourtney and Travis looked so in sync as she rocked a corset and leather trousers, while he teamed a leather biker jacket, with a beanie hat and checked trousers.
It was reported that during their trip to Sin City, Travis popped the question to Kourtney, asking the Keeping Up With The Kardashians star to marry him.
Sources claimed at the time: ‘I think Travis has been planning the proposal for ages.
‘They want to start their own family together – that is the bigger thing for them because they both have kids, but they want to bring the two families together.’

He allegedly got down on one knee while the couple were in Vegas to watch a UFC fight, with the insider adding: ‘Kourt’s never been married, and for years, told [her ex] Scott [Disick] she wasn’t interested because of her parents’ divorce.
‘She actually turned down Scott a few times – but things with Travis are different. They’ve talked a lot about marriage and the future.’
Neither Kourtney or Travis have publicly confirmed the engagement rumours.
Kourtney was previously in a nine-year relationship with ex Scott, who she shares three kids with; sons Mason, 11, and Reign, six, and daughter Penelope, nine.

The musician is dad to two kids, son Landon, 17, and daughter Alabama, 15.
Prior to dating, he and Kourtney were good friends. Both live in Calabasas and their families have known each other for a long time.
