Which of the following is NOT a benefit of aerobic training?

Aerobic training focuses on activities that enhance the efficiency of the cardiovascular system in absorbing and transporting oxygen to the muscles. One of its primary benefits is improved cardiovascular fitness, which means the heart and lungs are more effective during physical activity. Another key benefit is increased endurance; regular aerobic exercise allows individuals to sustain physical activity for more extended periods without fatigue. Weight management is also a notable advantage of aerobic training, as it helps burn calories, contributing to weight loss or maintenance.

Extreme muscle hypertrophy, on the other hand, is typically associated with resistance training rather than aerobic training. While aerobic activities can promote some muscle endurance, they generally do not lead to significant increases in muscle size (hypertrophy) as resistance training does. This is due to the different types of stimuli that aerobic and resistance exercises provide to muscle fibers. Thus, understanding the distinctions between the types of training can clarify why muscle hypertrophy is not a benefit of aerobic training.
