We all know that Rob Kardashian is trying to drop the weight that he gained during his break up from Rita Ora, and it seems like it’s a sensitive subject to him considering the way he speaks about it to the public. Last night, Kim posted a video of Rob working out on the tredmill in her room, and while he’s working out he is completely degrading himself by saying things like, “I can’t look at myself in the mirror”. Instead of Kim supporting him and trying to make him feel better about himself, Kim just laughs at Rob the whole time! Hit the jump and check the video out… Let us know what you think!
