Stress management techniques can improve overall fitness by reducing the impacts of stress hormones like cortisol on the body. Persistent stress can lead to physical symptoms, including fatigue, decreased immunity, and muscle tension, all of which impair fitness levels. Techniques such as mindfulness, meditation, and breathe exercises promote relaxation and recovery, enhancing mental clarity and motivation for exercise. By effectively managing stress, individuals can create a more balanced lifestyle that supports regular physical activity, leading to improved fitness outcomes and a reduction in stress-induced health issues.
