Skipping rope does not belong to aerobic exercise, because aerobic exercise means that the amount of oxygen inhaled is equal to the amount of oxygen consumed, and it can be achieved by keeping balance for more than 20 minutes and jumping at a uniform speed. If you can skip rope continuously for 20 minutes or more, consider aerobic exercise. So are other sports. The amount of oxygen inhaled continuously for more than 20 minutes is equal to the amount of oxygen consumed. Exercise to keep balance is called aerobic exercise.
