Abstract

While "micro" goals (small, frequent actions aimed at building lasting habits) have gained widespread popularity, their effectiveness in increasing physical activity remains underexplored. This study tested whether a daily, short-duration exercise goal increased physical activity more effectively than a standard goal of less frequent, longer workouts. Participants (n = 142) were randomly assigned to a micro goal group (3 min daily plus two 20-minute sessions weekly) or a standard goal group (two 30-minute sessions weekly). Participants tracked their daily exercise duration, enjoyment, and ease of adherence over 3 wk. The micro goal group exercised significantly more time overall than the standard goal group, with ease of adherence mediating this effect. The evidence supports using micro goals to increase physical activity and highlights their potential for habit formation and public health interventions.
