This study will evaluate the effectiveness of a virtual assistant-guided exercise program to improve adherence in older adults. In a nonrandomized controlled clinical trial, the experimental group will complete a 12-week, home-based program (60-minute sessions, 3 times per week) supported by a virtual assistant (BOT). The control group will comprise community-dwelling older adults already engaged in the municipal program Enguera se saludable, which delivers an in-person exercise program of comparable frequency and duration. The primary outcome is exercise adherence, defined as the proportion of prescribed sessions completed. Secondary outcomes include muscle strength, balance, functional capacity, health-related quality of life, and the user experience and usability of the virtual assistant.
