The best way to assess one’s physical fitness level involves a multifaceted approach, including tests for cardiovascular endurance, strength, flexibility, and body composition. Standardized tests such as the Cooper Test for endurance or the push-up test for strength provide valuable metrics. Additionally, engaging in fitness assessments with a certified trainer can yield precise evaluations tailored to individual goals. Monitoring progress over time through repeated assessments can help in setting realistic fitness goals and maintaining motivation.
