Exercising on the Elliptical Machine During Pregnancy

Dear Fitness Expert,
Is it safe to use an elliptical machine during the third trimester. If so, how long can I spend on it?

Yes, I love the elliptical machine. As you move into the third trimester, your joints are shifting and softening as your body prepares for childbirth. The pounding on a treadmill our outdoor jogging/walking can sometimes be too much, particularly if you already had knee or hip issues. The elliptical allows you to work on cardio without putting undue pressure on your joints.

Ahh, but there is a catch that you need to be aware of. Because it is indoors, because you will often have a fan on or A/C and because it is easier on the joints, you will likely go further and faster on this machine. As a result, your inner core temperature can spike without you even realizing how hot you actually are.

This is a problem because you do not want your inner core temperature to exceed 101° F. Your baby has no ability to sweat and regulate his or her own body temperature. As you pump away on the elliptical, you can make that baby oven of yours hotter than you should.

How to fix this?

And ... no, that doesn't mean, "Oh, goodie ... I get to sit on the couch and eat bon bons." It means that you need to buy a rectal thermometer. About every 20 minutes, you need to get off the elliptical and go to the bathroom. With your handy dandy rectal thermometer, check your temperature. If you are hovering at 100 degrees, take a walk to the water cooler, get a drink, cool down a little and hit the weights. If you are around 99 degrees, you can continue on if you so choose -- depending upon the time you have set out for yourself.

But be sure to get permission from your doctor first and, if you can, talk to a trainer. Pick up tips on how to work the machine and how you can add in light weights to sculpt, tone and prepare your body for the big day! Your body will thank you later!
