This article presents an analysis of the activity of students engaged in a yoga learning sequence based on the school form of practice proposed by the legislator in Physical Education, in continuity with the process of westernization of this practice. With reference to the framework of the course of action (Theureau, 2006), the aim is to shed light on the learning process, particularly the sensory learning of the practitioners, and more precisely to give an account of the place and the nature of the body sensations felt and interpreted.Self-confrontation interviews were conducted with two students engaged in a sequence of six yoga lessons. The analysis of the practitioners' experiences reveals their concerns, commitments and updated and constructed knowledge, in interaction with the didactic choices of the teacher. In the yoga activity, students are concerned by the good execution of the posture, by listening to their sensations and by optimizing postural comfort. The quest for postural quality is structured by listening to one's body and by building knowledge about one's body, based on both interoceptive sensations and sensations related to kinesthesia.These results invite to considere the supervision by teachers and the time necessary for the construction of perceptive and sensitive competences during the practice of postures, in order to act as close as possible to one's body possibilities.
