You should know the basics of fitness

1、What is aerobic exercise

Aerobic exercise belongs to the training of long endurance (more than 20 minutes, less than 60 minutes). It is required to complete a certain amount of exercise in a certain period of time with a certain speed and intensity through continuous and repeated activities (whole-body). During the whole exercise, we can smoothly complete the breathing process, but the breathing is slow and rapid (60-85% of the maximum heart rate). A certain heart rate is usually reached for training purposes. For example: long-distance running, swimming, skipping, aerobics, cycling, mountaineering and so on.

2、What is anaerobic exercise

Anaerobic exercise refers to the rapid and vigorous exercise of muscles in the state of "hypoxia". Anaerobic exercise is mostly high load intensity, instantaneous strong movement, so it is difficult to continue for a long time, and the time of fatigue elimination is slow. For example: weightlifting, sprinting, strength training and so on.

3、What is heart rate

Heart rate refers to the number of beats per minute. Different training objectives have different requirements for heart rate.
