Kim Kardashian West's early morning walks aren't for everyone!
In a new promo for Sunday's Keeping Up With the Kardashians, the 37-year-old reality star's seemingly simple exercise routine gets ripped by her best friend, Jonathan Cheban -- until she puts him to the test.
"I'm really impressed with your self-control. I think it's really good," Jonathan tells Kim in the clip. "It shows me that you are possibly thinking of changing a lifestyle."
"By the way, this is pretty good for somebody who eats 365 meals a day," he adds of his body.
