The correct answer is "cardiorespiratory endurance."
In cardiorespiratory endurance, the heart and lungs are trained by endurance training or repetitive training that heightens the aerobic capacity of the body and preventing cardiorespiratory decompensation (i.e. not getting shortness of breath after walking a few blocks). Non-stretching is detrimental because stretching is an important component of exercise to prevent exercise-mediated injury. Speed training and meditation are not components of health-related fitness.
