Key differences between strength and endurance training lie in their primary objectives. Strength training focuses on increasing muscle mass and maximal strength through lower repetitions and heavier weights, enhancing power and metabolism. In contrast, endurance training aims for increased stamina and aerobic capacity, typically employing higher repetitions with lighter weights or sustained cardio activities. The physiological adaptations differ as well; strength training promotes muscle hypertrophy, while endurance training improves cardiovascular fitness. Understanding these distinctions helps tailor training programs to fit specific fitness goals.
