What does overload do to the demands on your body?

Overload refers to a training principle that emphasizes pushing the body beyond its normal limits to induce physiological adaptations. When you increase the workload through greater intensity, frequency, or duration of exercise, you challenge your body's systems—muscular, cardiovascular, and metabolism. This heightened demand stimulates the body to adapt, leading to improvements in strength, endurance, and performance.

By applying the principle of overload, your muscles and other bodily systems must work harder than they are accustomed to, resulting in increased workload. This process not only promotes physical adaptations but also prepares the body to handle more challenging tasks in the future, ultimately enhancing overall fitness. Thus, the correct answer highlights that overload significantly increases the demands placed on the body.
