Age affects an individual’s optimal exercise routine by modifying fitness goals and physical capabilities. Seniors, for instance, may benefit from lower-impact activities such as walking, swimming, or cycling to minimize joint stress while still improving endurance and strength. Younger individuals might incorporate higher-intensity training to enhance performance metrics. Additionally, older adults should focus more on balance and flexibility exercises to prevent falls. Adapting workouts to align with one's age-related changes ensures safety and maintains effectiveness, allowing for sustainable physical activity throughout life.
