The body adapts to a new exercise program through a series of physiological changes that enhance performance and efficiency. Initially, individuals may experience soreness, but over time, the body becomes stronger and more coordinated. Key adaptations include increased muscle mass, improved cardiovascular endurance, and enhanced neuromuscular connections. As exercise becomes a regular habit, the body also becomes more efficient at utilizing fuel sources, leading to improved stamina and reduced fatigue. Consistent training results in long-term adaptations that support overall fitness and health.
