Smart mirrors that watch workouts and give real-time corrections move expertise from in-person trainers to algorithmic platforms, producing continuous biometric and performance data and standardizing training through vendor software. That creates new questions about who controls sensitive health data, who is liable if algorithmic coaching causes injury, and how access to algorithmic coaching reshapes fitness affordability and norms. — If fitness and bodily expertise become platformized, that reshapes privacy, commercial control of health data, and the social meaning of exercise.
