Khloe Kardashian names which sister she is VERY COMPETITIVE with (hint: it’s not billionaire Kylie Jenner): ‘We’ll be like, I am going to beat you at this!’

Khloe Kardashian says she is ‘very competitive’ with one of her sisters.

When they work out side by side, they always look over to see who is moving faster or exercising harder.

That is what the 38-year-old Good American designer told InStyle this week as she focused her chat on her health.

Khloe – who posed in a red top this week – has four sisters: older sisters Kourtney Kardashian, 43, and Kim Kardashian, 42. And she has two younger half sisters: 27-year-old Kendall Jenner and 25-year-old Kylie Jenner. Then there is her brother Rob Kardashian who is not often seen.

Can you guess which sibling Khloe competes with?

Work harder: When they work out side by side, they always look over to see who is moving faster or working harder. That is what the 38-year-old Good American designer told InStyle

It is Kim Kardashian, a mother of four whose ex-husband is rapper Kanye West.

Khloe told the site that they look to see what the other has done in the gym.

The subject came up when she talked how competitive the family is.

‘We are very competitive, especially Kim and I. We’ll be like, “OK, I’m going to beat the meters you got,”‘ she shared with a laugh.

Kim and Khloe were not always this close. 

It used to be Kourtney and Khloe who were best friends. But when Khloe welcomed her daughter True Thompson with ex Tristan Thompson, she leaned on Kim for advice. 

Kim has daughters North and Chicago as well as sons Saint and Psalm.

Also in her interview, Khloe said she loved getting a Hydrow rower after being inspired by her mom Kris Jenner.

‘She [Kris] loves it. She also just had a hip surgery, and the rower is so good on your joints. Her mobility is great, but she doesn’t [want to have] hard impact on things. 

‘And I’ve had three knee surgeries, and I also just like to switch up my cardio. 

‘I just never thought about rowing until I saw it at her house. And then I was like, “Oh, this is genius. I need something new to switch it up.”‘

Khloe added that Kris thinks she’s ‘so coo’l that she turned her on to something.

‘Some of the sisters or my mom sort of get mad if we’re taking things from one another, but we get inspired. I see cool stuff, I’m like, “Oh, I want that too.” It’s so funny that we become territorial over things.’

She called the machine ‘tranquil and beautiful.’

Close as can be: ‘We are very competitive, especially Kim and I. We’ll be like, “OK, I’m going to beat the meters you got,”‘ she shared with a laugh

Khloe said: ‘It’s so relaxing, the sound of the water. Sometimes I just need an outlet to get away. I’m not a big runner, so for rowing, the sound of the water, it makes me feel like I can do it much longer because it’s relaxing.

‘We don’t row in the same place together because we don’t have enough machines at one place because we work out together. If someone’s at my house, for example, I’ll be rowing while they’re doing a weightlifting set.’

And because she has a ‘huge phobia’ of whales, she is happy to stay out of the water.

‘A really weird phobia, I know. That’s a full other interview. There sometimes will be whales [in the classes] — I will have a panic attack seeing it, but my daughter is enamored. She’s like, “Mommy, there’s a whale.” I’m like, “Don’t draw attention to it.”‘

When she first started working out, she cared more about her weight.

‘I cared so much. Maybe [it’s] just being younger. I think you care about the scale,’ she shared. ‘The scale Fs with you. I don’t even look at a scale anymore. I think it’s really unhealthy. I haven’t in years. They’re just numbers.’

She then said the reason she turned to the gym was because of her divorce, which she has said many times in the past.

‘I didn’t really know what to do. Of course, in the beginning you [have to] get over that hump of it being really hard and something so new for you.

‘But I felt so accomplished. I’m sort of a control freak, but in life we can’t control everything. But the gym, what I put in it, I know I’m going to get out of it. And being a control freak — I’m proud of it — I love that I have that control.’
