What does progressive resistance training involve?

Progressive resistance training involves a gradual increase in the amount of weight applied to the muscles. This method is essential for building strength and improving muscle endurance. As the muscles adapt to the weight, increasing the resistance forces them to work harder, leading to greater strength gains and muscle development over time. This systematic approach not only fosters physical growth but also helps in preventing plateaus, where progress can stall if the same weight is lifted continuously without challenge.

Maintaining a consistent weight level, as suggested in one option, would not promote adaptation; similarly, decreasing weight would undermine the goal of increasing strength. A random alteration of weight lacks the structured approach necessary for effective muscular development and would not provide consistent overload, which is vital for progress in resistance training.
