Exercise intensity refers to the degree to which physical exercise stimulates human physiology. It is one of the main factors that constitute the amount of exercise. Exercise intensity directly affects the effect and safety of exercise, so determining exercise intensity is an important link in formulating exercise prescription. When making exercise intensity, we should consider the purpose of exercise, physical examination results, personal physique, exercise content, age, gender, exercise experience and other factors.

1. Indicators for evaluating endurance exercise intensity: maximum oxygen uptake, heart rate, metabolic equivalent, and level of consciousness fatigue;

2. Indicators for evaluating strength training intensity: load intensity, duration, number of repetitions and number of completed groups;

3, the evaluation index of tensile strength:

Fixed routine stretching exercises and aerobic exercise;

Increase the number of repetitions or action ranges of routines,

Complete the height of body posture and increase the intensity of exercise.

The exercise intensity of general stretching exercise and aerobics: generally divided into three categories: large, medium and small, measured by the number of knots.
