Finally, there's water. Staying well hydrated before, during and after exercise is always important. When you're well-hydrated, muscles and tissues function at peak performance and can help quell the desire for extra food. In the final months of pregnancy, drinking a lot of water can contribute to frequent trips to the bathroom. Do mild to moderate exercise three times per week.
Regular exercise is better and safer than intermittent exercise.
Avoid exercising while lying flat on your back after the first trimester, as this may restrict blood flow to your baby. Moderation is the key. Stop exercising when you feel tired or breathless. Never exercise to the point of exhaustion. Modify exercise to minimize problems with balance, oxygen and endurance that may occur as your pregnancy progresses.
