Swimming and running belong to aerobic exercise. The premise of aerobic exercise is that your heart rate is not more than 85% of the maximum heart rate and not less than 60%. The purpose of doing aerobic exercise can be divided into several types: reducing fat, improving your cardiopulmonary function, clarifying some toxins in the body and improving your muscle endurance.

From the point of view of nutrition, the pressure on running knees and ankles is relatively high, which is not suitable for high intensity. If you exercise and swim every day, it is full-body exercise, which is a very good choice for joint injury and muscle strain.

The conclusion is that swimming can completely replace running, and it is also aerobic, provided that it is best to do it in a constant temperature swimming pool. If the water temperature is too low or swimming in winter, this kind of exercise is very good for strengthening physical fitness, but there is a problem that it is very difficult to lose fat in the future and the business is very complicated. If the water temperature is higher than 29 degrees, the heart pressure will be very high, and it will feel depressed if it is far away.
