The vast majority of anaerobic exercise belongs to strenuous exercise, such as running, playing ball, and doing a lot of fitness. In addition, strenuous exercise is also related to physical fitness. People who exercise regularly have very developed cardiopulmonary function. During exercise, their heart rate can't exceed 120, they don't sweat and breathe smoothly.

On the contrary, if you lack exercise, doing 10 push-ups will make you sweaty and short of breath. If your heart rate exceeds 140 beats/min, push-ups will be considered strenuous exercise. Don't rest immediately after strenuous exercise, you can do some simple and mild exercise. And replenish water after the body recovers.

Extended data:

There is a significant correlation between heart rate and exercise intensity. When the intensity of exercise increases, the heart rate will inevitably accelerate, but when the intensity of exercise is high, we will feel very painful because of the accumulation of lactic acid and cannot persist.

In other words, people may be exhausted before reaching or approaching the maximum heart rate and can only stop to rest. People with good exercise ability can withstand the high lactic acid environment in the body and continue to increase their heart rate, which means that their ability is enhanced when they bear the ultimate load.
