Resistance training differs from endurance training primarily in its goals and methods. Resistance training focuses on building muscle strength and size through weightlifting and bodyweight exercises, working with high-intensity, lower-repetition sets. In contrast, endurance training aims to increase the body's ability to sustain prolonged exercise, using lower weights and higher repetitions or steady-state cardio activities, such as running or cycling. Both forms of training are essential for achieving comprehensive fitness, each offering unique benefits and contributing to overall physical health and performance.
