This article utilizes the theories of social bond and carnal sociology to analyze the role of the eductrainer in the sport-based intervention program DesÉquilibres. Methodologically, an action research study was carried out with three cohorts of adolescents. Our qualitative data collection was based on (a) interviews with 27 adolescents aged 14 to 17 years (cohorts 1 and 3), (b) a focus group of five eductrainers (paired with cohort 1), and (c) observant participation of cohorts 2 and 3. A thematic analysis revealed four principles-of-action constituting the social bond where risk-taking and its staging play an essential role: (a) a risky proposition to create the social bond, (b) recognition of the adult-in-the-making to anchor the social bond, (c) organization of the risky proposition to scaffold the social bond, and (d) physical commitment of the eductrainer to embody the social bond. Research has shown the potential of risk-taking to create and strengthen social bonds in the context of sports-based interventions.
