During Pregnancy exercise at a mild to moderate intensity and avoid exercise to the point of exhaustion. Exercise at least three days a week.
Exercise is always safest and most beneficial when performed regularly.
Avoid supine exercise after the first trimester. It can decrease the blood flow to the uterus. Avoid exercise in hot, humid environments and stay well hydrated. Drink water during your workout and wear cool clothing. Avoid exercise that can cause you to lose your balance, especially in the third trimester.
