For example, a runner might incorporate swimming or cycling into their routine. This variety helps to strengthen different muscle groups and enhances cardiovascular fitness while allowing specific muscles to recover. Additionally, cross-training can keep workouts interesting and prevent boredom. By mixing activities, individuals can maintain motivation and stay committed to their fitness goals. It is also beneficial for athletes in various sports, as it helps develop skills that can enhance performance in their primary activity, such as basketball or soccer.
