The study aimed to investigate strategies for promoting and sustaining regular exercise habits among rural housewives using the transtheoretical model (TTM). A semi-experimental study was conducted with 114 housewives aged 30 to 59 in Iran. The intervention group received a comprehensive educational program, and after 6 months, they exhibited significant differences in model structures, stages of change, and body mass index compared to the control group. These findings underscore the importance of physical activity training for rural housewives and suggest that the educational intervention utilizing the TTM substantially impacted the participants' model structures and stages of change.
