Can I keep exercising in pregnancy?

Yes, if you have been use to exercising prior to pregnancy, there is no problem to continue. Ideally avoid risky activities, e.g. Horse-riding, skiing, water skiing, rock climbing. Check with your doctor if you are unsure.
A good exercise programme will help weight control and build stamina, do on a regular basis and do not over do it. Drink plenty of fluids and check your pulse rate, it should not go above 140 beats per minute. Alternatively if you cannot maintain a conversation during exercise, this may mean that you are overdoing it.
Ideal exercises in pregnancy include, walking, swimming, and yoga.
Stop and consult your Doctor or Midwife if any bleeding abdominal pain, shortness of breath, and leakage of fluid from vagina or dizziness.
