What is the primary benefit of strength training?

The primary benefit of strength training is increased muscle mass. Strength training, also known as resistance training, involves exercising with resistance to build strength and size in the muscles. This process leads to muscle hypertrophy, where the muscle fibers increase in size due to the adaptation in response to the mechanical overload imposed during workouts. Increased muscle mass is essential not only for improving overall strength but also for enhancing metabolic rate, which can assist in weight management and overall health.

While improved flexibility, enhanced cardiovascular endurance, and better coordination are important aspects of overall fitness, they are typically more associated with other training modalities. Flexibility is primarily targeted through stretching and mobility exercises, cardiovascular endurance is improved through aerobic activities, and coordination can be enhanced through skill-based training. Thus, while strength training can contribute somewhat to these areas, its primary and most significant benefit lies in its ability to increase muscle mass.
