Weight training improves sports performance by enhancing muscle strength, power, and endurance. It helps build lean muscle mass, which contributes to overall athletic capability and can lead to improved performance in various sports. Strengthening muscles through weight training also enhances joint stability, reducing the risk of injuries during competition. Furthermore, incorporating resistance training into training regimens can enhance metabolic rate and improve body composition, giving athletes a competitive edge in their respective disciplines when executed alongside sport-specific training.
