Different fitness levels significantly affect exercise recommendations, as programs should be tailored to an individual’s capabilities and goals. Beginners may need low-impact activities to prevent injury and build a foundation, while advanced individuals may benefit from higher intensity workouts to challenge their endurance. Assessing initial fitness levels allows for personalized progression, ensuring individuals experience progress without discouragement or harm. Furthermore, adapting strategies promotes adherence to a fitness routine and fosters a long-term commitment to health.
