Getting physical exercise while pregnant is not only safe, it’s important. How much exercise you engage in while pregnant is determined in large part by how much activity you’re already accustomed to and the health of your pregnancy.
Certain conditions make exercising while pregnant a bad idea, so you should always check with your doctor before starting an exercise routine. In a healthy, normal pregnancy low-intensity exercise such as walking, jogging, swimming, stationary cycling, or low to moderate weightlifting can provide great benefits.
Be sure to avoid potentially dangerous activities like horseback riding or waterskiing as well as impact sports such as soccer or basketball.
