What does the term "cross-training" refer to?

Cross-training refers to the practice of engaging in multiple types of exercise to improve overall performance. This approach is beneficial because it allows individuals to work different muscle groups, enhance their cardiovascular fitness, and reduce the risk of overuse injuries that can occur from focusing solely on one type of exercise. By varying the workouts, a person can also maintain motivation and interest in their fitness routine.

In contrast to the other choices, which advocate for a narrow focus or specialization, cross-training promotes a well-rounded fitness regimen. It combines elements of strength training, aerobic conditioning, flexibility, and other forms of exercise, making it an effective strategy for improving athletic performance and fitness levels.
