Introduction: We developed the intervention Programa Vida Ativa Melhorando a Saúde (VAMOS 3.0). This behavior change program aims to motivate people towards an active and healthy lifestyle. Objective: describe the development process of VAMOS 3.0 in print and online formats. Methods: A methodological study of content analysis, structure, implementation, and evaluation were carried out to develop a new version of VAMOS 3.0. Results: The new version had changes in content (short, direct, and affirmative sentences, images, color palette), structure (increased number of sections, time of application), and implementation (duration, form of participation, monitoring). In addition to the printed format, an online program was created containing the same characteristics to expand the reach. Final considerations: VAMOS 3.0 is suitable for public health in Brazil and has promising strategies for application in basic health units, as well as in other types of institutions such as schools, government offices, gyms, public or private companies.
