The term for the body's ability to adapt to physical stress is called physical adaptation. This process involves physiological changes that improve strength, endurance, and overall fitness in response to consistent exercise. Through progressive overload, the body learns to handle increased stress, leading to enhanced performance and reduced injury risk. Adaptations may include muscle hypertrophy, improved cardiovascular function, and increased neuromuscular efficiency. Understanding physical adaptation allows individuals to adjust training approaches effectively, ensuring continued progress and motivation while promoting long-term health benefits.
