ACSM Personal Trainer Certification Practice Exam

Vigorous-intensity aerobic exercise should be performed for 20 to 60 minutes per day according to the ACSM guidelines. This recommendation aligns with the understanding that to achieve significant health benefits, individuals should engage in sustained bouts of vigorous activity that elevate their heart rate and challenge their cardiovascular system substantially.

The duration of 20-60 minutes allows flexibility in exercise programming, accommodating individual fitness levels and preferences. For some, 20 minutes may be adequate to achieve the necessary intensity, while others might benefit from longer sessions up to 60 minutes. This range is designed to promote endurance, cardiovascular health, and overall physical fitness, aligning with established fitness recommendations for adults.

Shorter durations, as suggested in the other options, would not meet the intensity benchmarks set forth by ACSM for vigorous exercise and could potentially limit the associated health benefits derived from such high-intensity activities.
