Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. “Aerobic” means “relating to, involving, or requiring free oxygen”, and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism.
“Ideally, our muscles should obey our will. Reasonably, our will should not be dominated by the reflex actions of our muscles.” (Joseph Pilates)
