To stay active amidst a busy schedule, prioritize scheduling workouts like any other appointment. Incorporate short bursts of physical activity throughout the day, such as taking the stairs or walking during breaks. Utilize time-efficient workouts, like HIIT, that provide maximum benefits in minimal time. Additionally, establish a routine, set realistic fitness goals, and find a workout buddy for accountability. Lastly, remember that even small, consistent efforts contribute significantly to overall fitness levels.
