Immediate effects of exercising on the body include increased heart rate, improved circulation, and enhanced oxygen delivery to muscles. These physiological changes facilitate better performance and support efficient energy production. Additionally, exercise triggers the release of endorphins, often leading to a sense of euphoria or reduced stress. Furthermore, muscle activation promotes strength and coordination, while increased body temperature helps flexibility and injury prevention. Overall, these immediate responses positively impact physical and mental well-being, encouraging individuals to maintain consistent exercise routines.
