Kim, 43, posted an Instagram Story video on Thursday, January 4, which showed Khloé, 38, behind the camera as her older sister did deadlifts. “Workouts w @khloekardashian really do it for me ,” read the caption. In the clip, Khloé commented on Kim’s intense technique several times while their trainer stood off to the side. “Oh, my God. What are you training for?” Khloé asked, to which Kim replied, “Life.” Khloé, however, joked that Kim was actually preparing for “The Olympics.” The Good American cofounder then pivoted to Kim’s other side before adding, “Holy f–k, you’re gonna f–k me up later!” Related: Kim Kardashian's Body Evolution Through the Years Before she welcomes her first child in July, see how the pregnant reality star's body has transformed over the past few years
