Kim Kardashian breaks a sweat wearing white tank top and black leggings for 'second' morning workout

She jumped back into a grueling fitness routine since the birth of her second child in December 2015 where she reportedly gained more than 60 lbs. during her pregnancy.

And Kim Kardashian, 37, showed off her hard-earned figure in a series of videos shared to her millions of followers on Instagram Saturday morning.

The svelte starlet sported a sweaty white tank top and tight black leggings as she gazed at her incredible form in front of a mirror at the gym.

'A few weeks to go and 60 pounds up! I look at other celebrities and Instagram girls who are literally so skinny right after giving birth,' she wrote in a blog post. 'How is that possible?!?!'

'We've been keeping a low profile and my sisters and I are closer than ever,' Kim quipped to the cameras. 

Cut to a series of clips of the sisters fighting, Kim yelling: 'You don't do f***ing s***. You're just f***ing a b**ch,' as Kourtney wipes tears from her eyes.
