Verified step by step guidance

1. Step 1: Understand the relationship between physical activity and stress by reviewing psychological research on how exercise impacts stress levels and emotional well-being.
2. Step 2: Recognize that physical activity is generally associated with reduced stress, as it can help regulate mood and improve coping mechanisms.
