User: why did you pick that one

Weegy: Aerobic exercise is physical exercise that intends to improve the oxygen system.[1] Aerobic means "with oxygen", and refers to the use of oxygen in the body's metabolic or energy-generating process. [ Many types of exercise are aerobic, and by definition are performed at moderate levels of intensity for extended periods of time. This also requires strengthening. ]
