Kylie Jenner suffers ‘burning’ exercise blowout as she endures ‘steep hill’ fail

Kylie Jenner suffered an exercise fail as she had a blowout as she tried to hike up a hill near her Californian mansion.

The 23-year-old Keeping Up With The Kardashians star is seen in a video on her Instagram Stories tackling a steep hill which may define why the area she lives in is called the Hidden Hills.

The makeup mogul set off in full confidence at what lay ahead of her as she filmed herself walking towards a dusty track the disappeared into the distance at a challenging gradient.

In a couple of following videos, the reality star shows that the hill is proving to be a little harder to climb than first hoped before she stops around half way and admits that |"it burns" as she contemplates her next step.

Kylie was joined by Maguire Grace Amundsen, who is the KUWTK star's executive assistant, and she was tagged in the post as the pair looked to up their fitness levels.

In the first clip that Kylie shared, they are seen heading towards the track, with the Kylie saying: "We’re about to go up this steep hill".

In the next clip, the pair are breathing a little heavier as Kylie shows how far they have come.

A third short video sees the mother-of-one confessing "Oh god, it burns," as she shows the long track back down the hill.

In a final clip, Kylie shows her white trainers as she claims "We made it," though it is unclear whether that was to the top of the hill or back down to the bottom.

The reality star also shared a short video of Maguire working out in a gym, wearing a matching pink sports bra and leggings.

Maguire asks: "They look good?"

To which Kylie replies: "They look very good."

While it is not completely clear what they are talking about, it would not be a surprise if it's Maguire's enviable abs as she works to keep herself looking so toned.
