The body adapts to regular physical activity through a series of physiological changes that enhance strength, endurance, and overall functionality. With consistent exercise, muscle fibers undergo hypertrophy, increasing in size and strength. Cardiovascular adaptations occur as the heart becomes more efficient at pumping blood, thereby improving overall stamina. Additionally, regular activity promotes better metabolic regulation and enhances bone density, reducing the risk of osteoporosis. These adaptations not only improve physical performance but also contribute to enhanced overall health, boosting the immune system and promoting longevity.
