First, train according to your physical condition. Some pregnant mothers who have never done fitness exercises and rarely do physical activities are more desirable to simply walk and do some slight stretching exercises. Too many complicated exercises that require great physical strength and energy loss are not desirable, and may be counterproductive, hurting the baby and the mother themselves, rather than achieving the effect of exercising.
Secondly, I'll introduce some suitable sports to you. Aerobic exercise is the first choice for pregnant mothers. The purpose of aerobic exercise is to sweat a little and maintain the level of cardiopulmonary function. Pay attention to sweating slightly and keep your heart rate slightly tired, which is easier to grasp and suitable for your own exercise. For example, the elliptical machine is relatively mild and suitable for pregnancy, but we must pay attention to the strength of the thighs and body, and don't let the knees be stressed. During pregnancy, your knees are really fragile because of the weight gain. Treadmill has a fast slope, so running is not recommended in case of insurance. You can adjust the treadmill slope to 3-5, and then walk for 20-30 minutes, sweating slightly. This is the first exercise I recommend to pregnant mothers. Secondly, because of posture changes during pregnancy, you will have backache. Shoulder training is very important. We can do small dumbbell boating or elastic belt boating, with a load of about 3kg on one side. Also, the chest will expand rapidly during pregnancy, so you must practice your chest muscles to prevent sagging breasts. It is important to gain weight quickly in the third trimester, and the footwall is unstable. You can do self-weight squats, because the load will increase the negative pressure, which will easily hurt the placenta and lead to bleeding. Pregnant women bring their own loads.
