Seasonal changes can significantly affect fitness motivations. During spring and summer, people often feel more energized and motivated to engage in outdoor activities, such as running, cycling, and hiking. Longer days and warmer weather promote a more active lifestyle. In fall and winter, shorter days and colder temperatures may lead to decreased motivation for outdoor exercise, prompting individuals to prefer indoor workouts or risk seasonal affective disorder (SAD). Additionally, holiday festivities can disrupt routines, making it challenging to maintain a consistent fitness regimen during these seasons.
