Kylie Jenner and Anastasia ‘Stassie’ Karanikolaou, both 22, have been BFFs since they were in their early teens. 

But on Wednesday, with many people looking to keep busy while in quarantine due to the COVID-19 crisis, Stassie teamed-up with Kylie’s sister Kendall Jenner for a workout with friend and fitness trainer Chase Weber. 

And both ladies used the session to flaunt their womanly curves to the delight of their millions of social media followers.

Let’s get physical! Kendall Jenner flaunted her midriff and statuesque legs, while Stassie put her booty on display during a workout with  fitness trainer Chase Weber on Wednesday

‘backyard workout with @stassiebaby @chasenfitness,’ Kendall, 24, captioned a selfie she snapped into a mirror near a rack of weights.  

The top model wore black fitted shorts and a matching sports bra that showcased her long, statuesque legs and toned midriff.

She also appeared to be wearing a harness, that’s oftentimes used for certain exercises, and had her long dark tresses pulled back into a ponytail with a part in the middle.

As Kendall snapped her photo, Stassie was caught in in the middle of doing a squat exercise, which required her to firmly stick her booty out while dipping down.

Kylie’s longtime friend opted for tight, white sports shorts with a matching sports bra and her long blonde locks in a loose ponytail.

The routine also included two large rubber bands, meant to add more resistance, that were secured around her thigh and ankle regions.
