Kylie Jenner is working on her fitness after welcoming baby No. 2.
The Kardashians star, 24, revealed the progress of her postpartum bod Friday on her Instagram Story, flashing her midriff in a mirror video. "My abs over here trying to make a comeback finally," Jenner wrote with the clip.
She previously put her figure on display in a custom Coperni white latex gown at Thursday's Hollywood premiere of her family's new flagship Hulu reality series The Kardashians. For her first red carpet since giving birth, she complemented the asymmetrical knotted number with a pair of thigh-high Amina Muaddi boots.

Jenner welcomed a baby boy in February with Travis Scott, with whom she also
shares 4-year-old daughter Stormi Webster. Although they announced his name as Wolf Jacques, the mother of two said last month that they've changed at least his first name, as Wolf "just really didn't feel like it was him."
A source told PEOPLE that Jenner will "share his name when she's ready." Another insider explained: "Kylie and Travis liked Wolf, but after getting to know their son, they felt like the name didn't fit him. They wanted to choose the perfect name that they both loved."
Last month, a source told PEOPLE that Jenner has become "extra mellow" since welcoming her second child, adding: "Becoming a mother of two has softened her even more."

"Kylie's such a good and nurturing mother. She really is the best mom and is always hands-on and doing things herself for the baby and Stormi. She's super sweet with those kids," the insider said.
The Life of Kylie alum previously admitted that her postpartum experience "has not been easy," sharing a candid update on her Instagram Story six weeks after going into labor.

"This experience for me personally has been a little harder than with my daughter. It's not easy mentally, physically, spiritually, it's just crazy," she said.
Kylie added: "It's OK not to be OK. Once I realized that I was putting some pressure on myself... And I just keep reminding myself I made a whole human, a beautiful healthy boy. We have to stop putting pressure on ourselves to be 'back.' Not even physically, just mentally, after birth. So yeah, just sending some love. I love you guys!"
The Kardashians premieres April 14 on Hulu.
