Do remember that exercise doesn't have to be strenuous to be beneficial.

Do try to keep active every day.

Do remember that the appropriate level of exercise will depend on how fit you were before becoming pregnant.

Do wear loose, comfortable clothes.

Do drink plenty of fluids, and don't allow yourself to get overheated, as this can be harmful to the baby.

Do take a gentle approach to exercises that put strain on joints and ligaments. During pregnancy, women are more vulnerable to joint and ligament injury because the body produces relaxin, a hormone that loosens joints and ligaments in preparation for childbirth.

Do listen to your body. Dizziness and fatigue is not uncommon in the first 12 weeks or so. Some women lose their balance later on as the baby grows and their centre of gravity shifts.

Do avoid contact sports and any activity with a potential for falling or being hit, such as horse riding, judo or skiing.

Do wear a supportive bra whilst exercising.

Do remember that if you can’t talk easily while exercising, you’re overdoing it, so slow down.

Don’t exercise in order to lose weight during pregnancy because this may harm your baby.

Don't do any strenuous exercise in hot weather.

Don’t exercise flat on your back, particularly after 12 weeks, because your bump presses on the big blood vessels, and it can make you feel faint.

Don't use saunas or steam rooms as the heat may be harmful to the baby.

Don’t skip the warm up or the cool down stretches when doing aerobic exercise.
