2. Physical fitness, muscle strength and various physical fitness tests. The human body is different, so it needs to be accurately tested to test the stretching ability of muscles in various parts of the body, the reaction speed of muscle contraction to the heart and so on. There are many methods for these tests, such as push-ups, pull-ups, squats, cardiopulmonary endurance tests, maximum heart rate tests, core competence tests and so on. Only by mastering these data can we design the trainer's exercise plan better and more reasonably.
3. Body composition test. This is generally tested by electronic instruments, and the body composition of the tester can be distinguished in detail according to the height, age and gender of the tester, so as to judge what state the tester is currently in. Now the gym also has this kind of instrument, which is more comprehensive and accurate, but at present, an electronic body fat scale is popular in society, which is very cheap and convenient, and can be connected to a mobile phone through Bluetooth for analysis. But the above data can only be used as a simple reference, and you can't believe it all. Because the machine is dead, the above data does not necessarily mean that you are in a healthy state. We must learn to analyze the above data in order to control our bodies better.
