The beginner target heart rate zone for the HRmax cardiorespiratory system is considered to be between 55% to 64%. This range is specifically for individuals who are new to cardio workouts and need to gradually build up their heart and lung endurance. Option B, 65%-74%, is a slightly higher range that may be more suitable for those who are already somewhat active and looking to challenge themselves. Option C, 75%-90%, is a moderate range that is generally recommended for individuals who have been consistently working out and have good cardiovascular health. Option D, 90%-100%, is a high range that is typically reserved for experienced athletes who have a high level of fitness and can sustain intense workouts for extended periods of time. Therefore, A is the most appropriate and safe target heart rate zone for beginners.
