Mental resilience is crucial in physical training as it helps individuals overcome challenges and remain committed to their fitness goals. Developing mental toughness enables athletes to push through discomfort and setbacks, ultimately leading to improved performance. This resilience fosters a positive mindset, allowing individuals to view obstacles as opportunities for growth rather than barriers. Training the mind alongside the body creates a balanced approach to fitness, enhancing motivation and perseverance, which are essential for long-term success.
