Quick Answer: For most uncomplicated pregnancies, staying active in the third trimester is generally beneficial. Focus on low-impact activities like walking, swimming, prenatal yoga, and pelvic floor exercises. Avoid lying flat on your back, high-impact activities, and anything with fall risk. Third trimester is the time to prepare your body for labor with squats, pelvic tilts, and breathing exercises. Always listen to your body, get your doctor’s clearance before starting, and stop if you experience warning signs.
