Abstract Health officials advocate for increased physical activity to address negative health consequences. While previous studies have investigated what motivates different individuals to exercise, the motives were not verified using unbiased measurements. Information and Communication Technologies (ICT), including wearables, are essential for collecting and sharing data necessary for improving health initiatives. The purpose of this study was to use objective measures collected by wearable devices (Fitbit) to track activity and explore whether specific exercise motives impact participants’ physical activities. Ninety-six college freshmen enrolled in the 90-day study. During orientation, participants completed an Exercise Motives Inventory-2 (EMI-2), and their current physical state was baselined. Partial Least Squares (PLS)—Structural Equation Modeling (SEM) was used to model the relationship between variables. The results revealed a relationship between Interpersonal Motives, Health Motives, and Fitness Motives, and participants’ physical activities. Those striving to facilitate a change in exercise behavior in young adults should leverage activities that align with their motives of interest and consider the use of wearable devices to track physical activity.
