What does the principle of overload in physical training emphasize?

The principle of overload in physical training emphasizes working harder than the normal exertion level. This principle is foundational for improving strength, endurance, and overall fitness. To promote physiological adaptations in the body, such as increased muscle mass, enhanced cardiovascular efficiency, or improved endurance, individuals need to apply a greater load than their body is accustomed to.

By progressively increasing the intensity, duration, or frequency of exercise, the body responds by adapting to those challenges, leading to improved performance over time. This approach encourages individuals to push their limits safely and effectively for optimal results in their training programs. Understanding this principle is critical for anyone looking to enhance their fitness levels or achieve specific health goals.
