2. Shorten or extend the exercise time: the exercise time refers to the total time or interval of each exercise, which ensures sufficient exercise time while ensuring a certain reasonable intensity and density.
3. Increase or decrease the exercise density: the exercise density refers to the number of repeated exercises per unit time, which reflects the relationship between time and quantity in the exercise load and is generally proportional to the exercise load.

Strategies for adjusting exercise load:
Exercise load should be gradually increased according to the changing law of human physiological function and activity ability and the adaptation law of human function. In the arrangement of teaching materials, high and low exercise load exercises can be arranged alternately, such as low-intensity walking and jumping and high-intensity running and jumping combination.
There are standard, bimodal, front high and then low, front low and then high exercise load modes. Standard type means that the exercise load gradually rises to a certain level from small to large, and then gradually decreases after a certain period of time. Shuangfeng style refers to the practice that students bear two kinds of high exercise loads in one class. The "high before and low after" type mainly means that the basic part of the class has a large amount of exercise in the first half and a small amount of exercise in the second half.
The former low and then high type is just the opposite of the former high and then low type, and the exercise load changes from small to large. The general adjustment strategy of exercise load should be the combination of high and low, alternating static and dynamic.
