Which benefit does strength training offer?

Strength training primarily focuses on increasing muscle strength and mass through resistance exercises. One of the benefits of strength training is indeed that it can lead to weight gain, but this weight gain is typically due to an increase in muscle mass rather than fat. This is generally seen as a positive outcome, especially for those looking to improve their overall body composition and physical performance.

Furthermore, while strength training is not primarily aimed at improving flexibility, certain strength training exercises can enhance flexibility as a byproduct. When muscles are strengthened, they can also become more functional, which can lead to greater overall mobility and range of motion in conjunction with flexibility-focused routines.

Thus, the answer encompasses the broader benefits that strength training can provide, including these aspects of weight gain through increased muscle mass and some degree of flexibility enhancement.
