In aerobic exercise, the training intensity is between 65% and 75%, so the training goal is to lose weight. Therefore, the elliptical machine with light weight and high frequency is suitable for fat-reducing training, and the training intensity is 75%-85%, so the training goal is to exercise cardiopulmonary function, so the elliptical machine with high weight stability rate is suitable for cardiopulmonary function training. If the training intensity is lower than 65%, the training effect is very small and cannot be shown. If the training intensity is greater than 85%, then the training purpose is to tend to professional training. Therefore, the intensity of aerobic exercise is directly related to the training effect.
