This article investigates action plans not as mental but as situated and observable activities in social interactions. I argue that projections and action plans can be understood as complex embodied practices through which actors prepare and coordinate further actions as part of a trajectory of a "communicative project". "Projections" within 'talk-in-interaction' are a central topic of conversation analysis (CA), e.g. for the micro analysis of the organization of turn-taking or for the identification of turn-constructional units. Aside from former CA-studies on syntactic and prosodic features, current research using CA from a multimodal perspective shows how embodied resources, such as gestures, serve as "premonitory components" of communicative actions. Using video data of communications in sports training in trampolining, I will show how communicatively situated "embodied action plans" are applied within pre-enactments and instructions for the production of embodied knowledge. Pre-enactments not only serve the production of an ideal imagination to corporally produce intersubjectivity. Pre-enactments are also used temporally for the multimodal and visibly situating of embodied action plans, to which actors can coordinate and orientate their current and prospective communicative actions.
