Pregnant Khloe Kardashian determined to maintain fitness routine despite criticism

Pregnant Khloe Kardashian is refusing to scale back her fitness regime despite facing backlash on social media.

The reality star, who is expecting her first child, began posting videos of her workouts on Snapchat over the Christmas holiday weekend (23-25Dec17), with one showing the 33-year-old using a StairMaster machine and lifting weights.

"I love that I can finally snap my workouts again... but Merry Christmas Eve and more workouts to come," she captioned the post.

However, many online users shared their disapproval of Kardashian adopting such an intense routine while pregnant, leading her to defend herself in a follow-up post on Twitter.

The blonde beauty hit back at her detractors and shared an article from fitpregnancy.com detailing the benefits of working out while expecting. She also noted she has been encouraged to keep moving by her doctor.

"For the ones who think they are physicians all of a sudden," she wrote, along with a face palm emoji. "MY doctor and I communicate and my workouts are cleared and highly recommended. Thanks kiddos! Don't make me stop sharing s**t."

Kardashian finally confirmed she is expecting on 20 December (17) via an Instagram post of her boyfriend Tristan Thompson's hands cradling her growing baby bump.

She wrote alongside the image, "My greatest dream realized! We are having a baby! I had been waiting and wondering but God had a plan all along."

On Monday (25Dec17), Kardashian shared that she is six months into her pregnancy.
