Which of the following is NOT one of the four tenants of physical fitness?

The correct selection identifies flexibility as not one of the four primary tenets of physical fitness. The four main components typically recognized in physical fitness are strength, endurance, cardiovascular fitness, and nutrition. While flexibility is an important aspect of overall fitness and health, it is often categorized under additional components or subcategories of fitness rather than being one of the core tenets. Therefore, emphasizing the significance of strength, endurance, and nutritional balance aligns directly with foundational principles of physical fitness that are crucial for overall performance and well-being. Understanding these tenets is essential for developing an effective physical training program that meets various fitness goals.
