Which component of fitness is primarily developed through resistance training?

Resistance training primarily develops muscular strength and endurance. This form of exercise involves the use of resistance, such as weights or resistance bands, to challenge and enhance the muscles' ability to exert force and sustain activity over a period of time. By progressively overloading the muscles during resistance training, individuals can stimulate muscle hypertrophy and improve their overall strength levels as well as their muscular endurance.

While flexibility, cardiovascular endurance, and agility are important components of physical fitness, they are not specifically targeted through resistance training. Flexibility is usually developed through stretching exercises, cardiovascular endurance is improved through aerobic activities like running or cycling, and agility focuses on the ability to change directions quickly and effectively, which often involves specific drills rather than pure resistance training.
