It is suggested that we should not invite private teachers, observe the teaching of several coaches and try to chat up their students to find out. Personal experience in choosing private education can be shared as follows: it is best to find a same-sex private education with similar body size-because it is impossible to quickly evaluate the level of private education in a short time, which means that your private education may encounter problems in the process of fitness, and he can quickly help you correct and overcome them according to his own experience (or find a private education with your expected body size); 2). If you need to practice muscles, it is recommended to find a bigger male personal trainer-because muscle training often means strength training of equipment, and a major role of personal trainer is sports protection. If you find a petite and thin female tutor, do you think she can hold you back when the barbell falls? 3). On the premise that it can be recognized, find a personal trainer with long working hours and many training programs-generally speaking, long working hours means that he/she has experience and enthusiasm for fitness, while training programs mean that he/she has comprehensive knowledge, and can help you adjust standard movements according to your characteristics, and even help you adjust and decompose fitness goals in order to better achieve them; 4). Expensive is generally reasonable, but not necessarily the most suitable. It is suggested to ask (or take an examination of) personal education with your own questions about fitness to see if his answers are reasonable and useful. A really good personal education is to tell you the principles or key points without hesitation. Only amateurs will worry, and if they know it, they won't invite private teachers. No matter which private tutor you invite, it is most important to clarify your goals in advance, or communicate with the private tutor well, so that he can analyze your needs and goals and make a plan to achieve them.
