There are many fitness exercises suitable for pregnancy, but we need to pay attention to the intensity and mode of exercise. Generally speaking, low-intensity exercise, such as walking and stretching, should be carried out in the first trimester. The movement should be slow and small, at least five times a week, and each exercise lasts for 20 minutes to 30 minutes. Moderate-intensity exercise should be carried out in the second trimester, such as aerobics and swimming for pregnant women. During this period, the focus of exercise is to enhance physical fitness and improve self-immunity.

In addition, there are some precautions:

-Warm-up exercises must be done before exercise to avoid cramps.

-The heart rate during exercise should be within 140 beats per minute.

-Exercise time is 20-30 minutes every day.

-The amount of exercise is below moderate intensity.

-For pregnant women, the limit of exercise is not tired, relaxed and comfortable.

-replenish water in time before, during and after exercise.
