Mainly because the obese people in China have no sports foundation and know nothing about sports. It's good that the wrong and backward physical education in school won't ruin you. There is indeed a big gap between the sports and training bases of China people and foreigners.

Therefore, most responsible coaches will definitely not advise you to start with comprehensive intensive training from the beginning.

For example, the arrangement of group calisthenics abroad, aerobics, boxing, step exercise, dumb exercise, barbell, etc., are really not suitable for obese people in China. Their individual qualities are more complicated, and everyone's physical fitness is different, and they don't know if they are sick. Isn't it asking for trouble to engage in high-intensity comprehensive aerobics directly? It is not a matter of persistence at all, because it is more scientific and prudent to arrange your own fat-reducing fitness training plan.

For beginners, it is necessary to learn one action at a time and improve their own ability in order to complete the fat-reducing training more effectively, safely and healthily.

Never suggest that it is best to participate in complex sports blindly without knowing your own abilities.
