The body adapts to consistent exercise over time through various mechanisms, including increased muscle mass, improved cardiovascular efficiency, and enhanced metabolic rates. Regular training stimulates physiological changes, such as increased capillarization (blood vessel formation), delivering more oxygen and nutrients to working muscles. Additionally, the body becomes more efficient at utilizing energy substrates, like fats and carbohydrates. These adaptations lead to improved strength, endurance, and overall performance. Importantly, consistency in training is key to maximizing these adaptations and progressing toward fitness goals sustainably.
