Answer:To find your initial data, honestly reflect on your current exercise, stress, sleep, and diet habits. You can also use fitness trackers, sleep apps, or food diaries to get more detailed information. To take action based on national recommendations, aim for at least 150 minutes of moderate exercise or 75 minutes of vigorous exercise each week, include strength training, eat a healthy diet with fruits, vegetables, whole grains, and lean protein, and get 7-9 hours of sleep each night. Remember, it's okay to start small and gradually make changes to improve your wellness and fitness.
