Suitable benchmarks to measure fitness progress can include several key metrics. Objective measures may involve assessing cardiovascular endurance through timed runs or aerobic tests, muscular strength via maximum lifts or resistance training sessions, and flexibility through reach tests or range of motion evaluations. Subjective measures, such as perceived effort or changes in how clothing fits, can also provide insight. Additionally, tracking body composition changes, such as body fat percentage or muscle gains, offers a more comprehensive overview. Establishing and reviewing these benchmarks enables individuals to set goals and celebrate milestones during their fitness journey.
