Stress can significantly impact physical health and fitness goals by triggering physiological changes, such as increased cortisol levels. Elevated cortisol can lead to weight gain, particularly in the abdominal area, and hinder muscle recovery. Additionally, stress may decrease motivation to maintain a regular exercise routine or adhere to a balanced diet. This creates a negative feedback loop that affects overall health. Effective stress management techniques, such as mindfulness or relaxation exercises, can help mitigate these impacts and support the achievement of fitness goals.
