The term "cross-training" in sports refers to a training regimen that incorporates various fitness activities to enhance overall athletic performance. By diversifying workouts, athletes can develop skills not typically addressed in their primary sport, leading to improved strength, flexibility, and endurance. For instance, a runner may include swimming or cycling in their routine to build cardiovascular fitness while reducing the risk of overuse injuries. Cross-training helps athletes maintain motivation, balance muscle development, and prepare for the demands of competition through a comprehensive fitness approach.
