Final answer:
The practice of increasing weights in weight lifting to gain strength is an example of the Overload Principle, which requires progressive intensity for muscle growth.
Step-by-step explanation:
The concept of weight lifting to become stronger and lift heavier weights is an example of the Overload Principle.
This principle emphasizes that in order to improve muscle strength and endurance, one must increase the intensity of the exercise over time. As you continue to lift weights, the muscle adapts to handle the current load.
To continually gain strength and increase muscle mass, the weight or resistance must be progressively increased, which challenges the muscles even further and forces them to adapt by becoming stronger.
