Now is the era of national fitness, and the competition of fitness clubs is becoming increasingly fierce. First of all, you must be very familiar with and understand your club, and spend some time learning fitness knowledge, such as fitness, physique, or fitness to lose weight, fitness and shape. When you understand this as a topic, tell the people around you what you know. Introduce people in your circle of friends first (you don't harm them, fitness is a good thing). After you find self-confidence and fully master this knowledge, you will find that everyone around you is your development goal ~!
