A well-rounded fitness assessment should include several key attributes. First, it should evaluate cardiovascular endurance, testing how efficiently the heart and lungs work during exercise. Second, it should assess muscle strength and endurance, focusing on major muscle groups. Third, flexibility and balance tests determine the range of motion and stability. Additionally, body composition analysis can give insights into fat and muscle ratios. Finally, health history and lifestyle factors should be reviewed to create a comprehensive view of an individual’s fitness level.
