Your own situation. Practitioners are different in age, physique, health status, personality, technical level, study and work characteristics. Only by determining the appropriate exercise from this reality can we improve the exercise effect. For example, teenagers in the period of sudden height increase can practice stretching more, introverts should participate in group activities more, and mental workers can choose aerobic exercise that can promote brain cell activity and enhance cardiopulmonary ability.
The purpose of exercise. When participating in sports activities, different purposes, contents, methods and loads will be different. Taking running as an example, if you are ready to participate in the competition, you need to have greater intensity; If it is fitness, low-intensity uninterrupted jogging should be adopted, and the duration of each time should not be less than 5 minutes; When the main purpose is to lose weight, the duration is preferably not less than 20 minutes.
Activity environment. If possible, try to exercise in a place with fresh outdoor air and beautiful environment. In addition, it is also necessary to prevent accidents due to poor exercise environment.
Select the project. Different exercise programs have different exercise values. If you want to lose weight, you should choose aerobic exercise that consumes obvious body fat, such as long-distance running and swimming.
Amount of exercise. For ordinary junior high school students, moderate-intensity activities should be the mainstay. During the activity, the average heart rate should be kept at 130 times/minute, the exercise duration should be 40-50 minutes, and exercise 5-6 times a week, so as to obtain better exercise effect.
