What distinguishes progressive resistance training from other training methods?

Progressive resistance training is characterized primarily by the systematic increase of resistance used during strength training exercises to enhance muscle strength and hypertrophy. This method is distinct from other training approaches because it focuses on continually challenging the muscles by incrementally raising the weights or resistance over time. This increased demand on the muscles necessitates adaptations that result in strength gains and improvements in muscle size.

In contrast, while some training methods may incorporate elements like aerobic fitness or flexibility, they do not emphasize the incremental increase in resistance as a core component of the training regimen. This focus on progressive overload is fundamental to building muscle and strength, which is what sets progressive resistance training apart from other forms of exercise that do not prioritize this principle.
