Ouch: Khloe Kardashian took to Instagram on Monday morning to share videos of herself working out. During one of the Insta Stories clips the 38-year-old beauty – who is 5ft10in – claimed that she was exerting herself more than usual as she pulled 100lbs worth of weights

Thinner than ever: The Keeping Up With The Kardashians vet was having difficulty with the workout as he weighs only 123lbs, it has been claimed, after recent weight loss; seen last week

‘Bear crawls with pulling over 100 pounds,’ she wrote over a photo as she linked to Don-A-Matrix Training.

Over a video the TV siren wrote, ‘I do not care about my form here. I am dying. An hour of torture from this monster Don-A-Matrix.’

She is referring to Don-A-Matrix, a workout center on Melrose Avenue in Los Angeles.

Khloe wore a light brown crop top and leggings with her honey blonde hair pulled up into a ponytail as she stopped to take selfies in the mirror.

He has often appeared on KUWTK as he trains Khloe as well as Kourtney on the grounds of their mansions.

Speaking to USA Today, Khloe recently admitted that ‘it was hard’ to learn the news of Tristan’s latest infidelity while cameras were capturing her every move.

In 2018, just days before Khloé gave birth to her and Tristan’s daughter True, DailyMail.com published video and photos of Tristan kissing a strip club worker and also taking her up to his hotel room in New York City.
