Robert Greene, M.D. provides some specific principles on fertility and exercise:
Principle One: Start a balanced exercise program which should incorporate aerobic activity, strength-building exercises, and flexibility training. If you are currently inactive, it typically takes two to three months to achieve a healthy level of fitness.
Flexibility and balance improves the range of motion of joints and muscles to help your coordination and agility. Activities that promote balance and flexibility include:
Principle Two: Activate your Lifestyle by staying active even in your “downtime”. A study of a group of students that were given 1000 extra calories a day found that the students that were very active did not gain weight. In this case, active is defined by informal everyday activities such as standing, fidgeting, or just walking around. Some suggestions for burning these extra calories without really trying are:
Principle Three: Cut back on excessive exercising. Studies have shown a relationship with vigorous exercise and fertility issues. Some warning signs of excessive exercise are sleep disturbances, prolonged soreness, chronic muscle soreness, missed menstrual cycles or an elevated resting heart rate. Even if you are not exhibiting these symptoms but suspect that you are overdoing it, here are some ways to cut back:
Principle Four: Create a longer lasting change so that exercise becomes a habit. Some suggestions for creating this type of change are:
Exercise is a necessity in increasing fertility with men and women. First, exercise helps to reduce insulin resistance by allowing the muscles to more efficient in taking in glucose, helping to keep blood sugar levels stable. Exercise also lowers stress hormones which can get in the way of fertility. It improves blood flow to the pelvic area so that the uterus and ovaries have a strong oxygen supply, improves immune function by lowering inflammation (which can interfere with implantation of the fertilized egg), helps you have more energy and normalizes circadian rhythm so that you sleep more soundly. As fitness improves, so do energy levels and mood, contributing to a more fertile you.
