Exercise physiology examines how physical activity affects the body’s systems, which is crucial for understanding how exercise aids in obesity management. Regular exercise increases energy expenditure, improves cardiovascular health, and promotes fat loss, making it essential for weight management. Aerobic exercises, such as walking, swimming, and cycling, help burn calories, while resistance training strengthens muscles and increases lean body mass, enhancing overall metabolism. Exercise also influences hormonal responses, reducing appetite and boosting mood-regulating hormones like endorphins. By understanding exercise physiology, individuals can adopt structured, effective workout routines that are safe and suitable for weight loss, reducing obesity-related health risks, and promoting long-term well-being.
