Among the athletes listed, the cross country runner is likely to use the least amount of weight training in their preparation. Cross country running primarily focuses on endurance, aerobic fitness, and running technique, with training often emphasizing long distance runs and interval training rather than heavy weight training.
While strength training can be beneficial for all athletes, the specific demands of cross country running make it less reliant on weight training compared to football players, wrestlers, and baseball players, who require more strength and power for their respective sports.
