How can i exercise safely during pregnancy?

Do...: The same things you would normally do during your exercise program. Cardio, resistance, jogging, walking, etc. However avoid risky activities where falling is a risk. You will need more water (carrying extra weight), so stay hydrated. Also the added weight will incrementally lower your efforts, compared to non-pregnant. And drink fluid and avoid hyperthermia. Always stretch.

Be smart: In the absence of medical or OB complications, pregnant women should continue to exercise at a moderate level for 30 minutes a day most days of the week. Speak with your doctor if you are unsure if exercise is safe for you. Knowing when to stop (vaginal bleeding, chest pain, shortness of breath) and avoiding high risk exercises (scuba diving, high risk of falls, contact sports) is important too.
