(1) evaluation In the evaluation, the private tutor looks for the needs of the guests, understands the current lifestyle of the guests, and suggests that the guests make adjustments. Evaluating guests is the first process and the most basic step of private education, which can provide valuable information for private education and guests. It is also the measurement and evaluation of physical fitness, and provides the best way (way) to collect the information of guests' current health status and physical fitness level. The so-called measurement is to test the physical condition and physiological indicators of the guests; Evaluation is to give the guests a comprehensive evaluation based on the measured data and indicators. In fact, it is relatively easy to make measurements. As long as you master the basic requirements, steps and precautions of the test, you can measure accurate data and physiological indicators. What is difficult is how to give the guests a more comprehensive, comprehensive and accurate evaluation and put forward scientific and constructive suggestions according to the measured data and indicators. This requires private education to have strong professional skills and comprehensive level. For example, making exercise prescriptions, reasonable diet suggestions and so on. For another example, when you detect that the guest has high blood pressure, tell the guest what causes the high blood pressure, and what fitness methods and diets can be improved and recovered. To sum up, measurement is to find problems; Evaluation is to analyze problems; Teaching is to solve problems. It can be seen that the ability to find, analyze and solve problems is an important condition to become an excellent personal trainer.

(2) Safety In the teaching process, we should adhere to the principle of safety and effectiveness, prevent hidden dangers in sports, and ensure the safety in the following aspects:

1. Before the lecture, remind the guests of the safety issues of fitness, such as wearing sportswear and fitness safety protection articles (such as knee pads, wrist guards, gloves, etc.). ) prevent hidden dangers in fitness exercise.

2. Why do you warm up before fitness? Do stretching after fitness. Why? It is necessary to explain and explain clearly to the guests. In other words: let the guests taste it and know what it is.

3. In terms of teaching safety, if the guests are under great pressure, it is recommended not to do antagonistic or intense sports (such as playing basketball, playing football, spinning, running fast, skipping rope, etc.). ). This will increase the burden on the heart, lead to an increase in blood pressure, cause hypoxia, and cause adverse reactions such as shock. If you are obese (overweight) and lose fat, don't run fast at the beginning, it will be dangerous. First, cardiopulmonary function can't keep up, which will increase the burden on the heart; Secondly, it will increase the possibility of injury accidents such as disc compression and knee joint strain. Suggesting the best way for guests (such as riding a strength exercise bike or walking on a treadmill) can prevent the hidden dangers of fitness exercise. After losing weight and excess subcutaneous fat, guests choose the combination of treadmill and strength exercise bike. Tip: If you do aerobic exercise for 30 minutes, you can choose the treadmill (difficulty is preferred) for the first 15 minutes, and then ride the strength exercise bike 15 minutes. The advantage of this is that with the decline of sports ability, the difficulty will also decrease. This can reduce the psychological pressure of the guests, which is not only safe, but also can improve the training effect and enrich the training content and entertainment. If the gym doesn't have a strength exercise bike, you can choose to sprint on the treadmill, and the effect is good.
