Personal Trainer Corner: Exercise For Fertility
26 Oct 2011
Women who exercise during pregnancy usually have a more comfortable pregnancy and faster postpartum recovery. If you’re not a gym fan pre-pregnancy is a good time to find a low-impact form of exercise you enjoy doing so that your body has time to get used to it. Starting an exercise program now is much better then starting a program when you are already pregnant and feeling the ups and downs of your first trimester. Pre-pregnancy is a great time to really work on your stomach muscles, especially your lower abs, they do a lot of work doing pregnancy.
We need to exercise. Our bodies thrive on movement, and quickly degenerate without it. It is also essential for fertility, weight loss and handling stress. Inactivity deprives muscles of the constant push and pull they need to stay healthy. It also saps their ability to respond to insulin and to efficiently absorb blood sugar. When that leads to too much blood sugar and insulin in the bloodstream, it endangers ovulation, conception, and pregnancy.
You don’t need to be fit to be fertile, but it helps. If you are in reasonably good shape this increases your chances of conceiving quickly and having an easier birth. Exercise also helps reduce stress, promotes good sleep patterns, improves your circulation and improves your feeling of both physical and mental wellbeing. And when you’re feeling good your confidence and sex drive increase.
Unless you are extremely lean and don’t need to lose weight exercise is a must for fertility. Research shows that for every hour of vigorous activity per week there was a 7 percent reduction in infertility. Vigorous intensity exercise causes a substantial increase in breathing or heart rate making having a conversation difficult, having a “perceived exertion” of 15 or greater and can burn more than seven calories per minute.
Perceived exertion is based on a scale that was developed by Dr. Gunnar Borg. It is based on how hard you perceive you are working. The scale runs from “no feeling of exertion” which rates a 6, to “very, very hard”, which rates a 19 or 20, this means you are exercising so hard you couldn’t possibly push yourself any harder. It runs from 6 to 20 to roughly correspond to your heart rate by multiplying your perceived score by 10 should give you your approximate heart rate.

Working your muscles is good for ovulation and conception as well as being an integral part of losing or controlling weight and keeping blood sugar and insulin in check. A single exercise session speeds the entry of blood sugar into muscle cells and improves their sensitivity to insulin, which, as we now know, is important for fertility.
Some women need more exercise then others for their weight or moods and others are active just because they enjoy it. Some who need to be active aren’t, while a small number of others are too active. Most women should be getting at least thirty minutes of exercise every day, unless your BMI is over 25, then you may need to exercise for longer. If your BMI is below 20 then you may need to cut back for a little while, we will discuss BMI and the “fertility zone” later.
