Those female contestants are naturally good in physical fitness, hard in training and demanding in nutrition. 95% of men can't bear the amount of training they do.
The coach is right. If you want to lose weight and shape, you have to do this. Your point of view is a bit general. Women always think that they will become muscular men after practicing a few times. If nothing else, look at the men who have worked hard in the health club. How many people are muscular? It is difficult for women to grow muscles because of hormones, and the amount of exercise you lose weight is not as good as that of professional bodybuilding. Do you exercise your muscles like this to kill your popularity?
It's almost impossible for you to become a muscular person with a casual practice, just as I became Liu Xiang with a casual practice. If you really practice so casually and become a muscular man, then I envy you too much, and I will rely on you to win glory for China bodybuilding in the world.
