The 35-year-old reality star can be heard adorably joking to North, "That's a tough workout."
The little girl was dressed in all-red, which Kim pointed out in another snap, writing, "She thinks it's Valentine's Day EVERYDAY!!!!!" She even added "not kidding" over the outfit using the app's drawing tool.
A few hours later, Kim shared even more adorable videos while in the car with her husband, Kanye West, and North.
Kanye can be seen giddily bouncing along to tunes, many of which Kim was lip syncing to on Snapchat.
The Keeping Up With the Kardashians star even caught a glimpse of North, who was sitting behind her in a car seat, while filming one of the clips. "I see you there," Kim laughed to her daughter.
Despite her frequent presence on Kim's Snapchat, North isn't a big fan of the app. On Thursday, she explained that the various filters scare her daughter.
