Assessing one’s fitness level can be done through various methods, including physical tests and self-evaluations. Common benchmarks include measuring cardiovascular endurance through activities like the 1.5-mile run or step test, strength using maximum lift tests or bodyweight exercises, and flexibility with sit-and-reach tests. Assessing body composition through BMI or body fat percentages also provides insight into overall fitness. Additionally, monitoring daily activity levels and perceived exertion during workouts can help gauge progress. Regular assessments help individuals adjust their fitness programs accordingly.
