1, serious (important place, leadership), demanding, simple and best, imposing manner, which is the slogan of cooperating with you to eat;
2. If you are in a private gym, you can be funny and cheerful, your movements can be neat and best, and any movements can be awkward;
3, if it is outside the gym, doing exercises, shouting slogans, attracting people, it is really a warm-up exercise suit+the part you want to promote, action exercises. Simply put, the public can do it and imitate it to the extreme.
I hope it helps you.
