Strength and endurance are complementary aspects of fitness that work synergistically in physical training. Strength training, focusing on building muscle mass and power, enhances overall force production, while endurance training improves the body’s ability to sustain prolonged exercise. Strength provides the foundation for endurance activities by enabling more efficient muscle contractions over time. Conversely, increased endurance can enhance strength training performance by improving metabolic efficiency and recovery between sets. Together, they promote a well-rounded fitness regimen, increasing overall physical capacity, functional ability, and reducing risk of injuries during various activities.
