Physical fitness should have a training plan, gradually increase the amount of exercise and the complexity of exercise, so that the collective can have a gradual adaptation process to prevent exercise fatigue and injury. Then, let me share with you the basic principles of fitness. Welcome to read and browse.

First of all, the principle of suitability

FIT is the abbreviation of three English words: Frequency, Intens and Time. It is the basic monitoring principle that we must adopt when engaging in health-oriented sports.

Number of times: indicates a person's cycle, such as the number of times a person exercises every week.

Intensity: that is, the intensity of exercise. The intensity control of aerobic exercise can be achieved by measuring the heart rate. When doing aerobic exercise, the heart rate should be controlled between 60% and 80% of the maximum heart rate. In strength training, the principle of FIT monitoring can be implemented by adjusting the weight of training equipment and the number of exercises.

Time: refers to the duration of each exercise. In order to improve the endurance of cardiopulmonary circulatory system, aerobic exercise should be carried out for at least 20-30 minutes.

Second, the overload principle

Physical fitness should have a training plan, gradually increase the amount of exercise and the complexity of exercise, so that the collective can have a gradual adaptation process to prevent exercise fatigue and injury. Overload principle refers to the fact that when doing physical exercise, the body or specific muscles are stimulated more strongly than when they are not exercising, or the stimulation intensity that they have adapted to is stronger.

Third, the principle of gradual progress.

The gradual principle is an extension of the overload principle. This principle means that when implementing an exercise plan to enhance a certain physical quality, the load should be gradually increased.
