Kylie Jenner, 25, show off her slim figure during workout after dropping over 40LBS following son's birth last year (Photos)

In a series of videos posted on Friday, Kylie Jenner flaunted her amazing curves on Instagram.

The 25-year-old reality TV actress showed off her hourglass figure while filming herself working out on the treadmill while wearing a sports bra and matching biker shorts from Alo Yoga.

The social media influencer also wore off-white training shoes and a pair of tall, white socks with red accent.

The creator of Kylie Cosmetics, who the day before wore a Matrix-inspired ensemble to Nobu Malibu, left her raven black hair down while working out.

She looked to be displaying a fresh makeup-free face in advance of the debut of her new mascara before releasing a video of herself getting ready after working out.

Instead of including a caption, the businessperson tagged the sports wear company and added two crossed-fingers emojis.

Jenner released a candid video of herself getting ready after publishing the training videos.

She applied her new mascara and held out the pink bottle and the matching pink compact from her company, displaying her beautiful lashes.

In addition, she posted a professional close-up photo of herself on her primary social media account.

The brunette beauty looked gorgeous with little makeup that brought attention to the adorable freckles on her nose.

She had a warm brown wash over her eyelashes and a chocolate lip that was overlined in the picture.

She seemed to be applying mascara while gazing up as her well-groomed fingers delicately brushed her lips.
