Kim did admit that despite her enthusiasm to exercise, she is prepared to work hard in order to reach her targets. "This is going to be sooo [expletive] hard but I can do it," she said. "And I can't wait to share it all with you! #BeastMode #WhosWithME ?!?!?!"

Although the star has been an active presence on social media in recent months, she has been keeping a relatively low profile and has not yet made an official appearance since giving birth to Saint before Christmas.

The little boy is Kim and Kanye's second child – the couple also have an adorable two-year-old daughter named North.

Kim caused a social media frenzy when she shared the first photo of Saint, which sees the newborn holding hands with his older sister. Proving that North has already bonded with her new sibling, Kim captioned the sweet photo: "She said 'he's my best friend.'"

The mum-of-two originally uploaded the picture on her app under the headline 'BFF' before sharing the candid snap with her 58.2M Instagram followers.
