I can tell you that the third trimester is suitable for doing some mild and low-risk exercise. These exercises can help you keep healthy, enhance muscle strength and flexibility, reduce discomfort and prepare for childbirth.

Here are some exercise suggestions suitable for the third trimester:

1. Walking: Walking is a simple and effective exercise mode, which can improve cardiopulmonary function, enhance leg muscle strength and relieve leg edema symptoms.

2. Swimming: Swimming is a low-impact exercise with less pressure on joints and muscles. At the same time, buoyancy in water can reduce the weight of the body and relieve back pain and edema.

3. Yoga: Yoga for pregnant women can help you relax and enhance muscle strength and flexibility. Choose a yoga class suitable for pregnant women to avoid overstretching and handstand.

4. Jogging: If you are used to jogging, you can continue jogging moderately. But please make sure that your doctor has approved it and follow appropriate safety measures, such as choosing a flat road surface to avoid strenuous exercise and overwork.

5. Fitness Ball Exercise: Using fitness balls for some simple exercises in the third trimester, such as pelvic inclination and pelvic circle drawing, will help to strengthen the core muscles and stabilize the body balance.

No matter what kind of exercise you choose, you should ensure that you feel comfortable and avoid overwork and strenuous exercise. Before starting any new exercise program, it is best to consult your doctor to ensure that your personal situation is suitable for these activities.
