Unless your doctor has told you otherwise, your body's ready to exercise. Even now, though, your joints and ligaments may still be loose from the effects of pregnancy, so go easy at first, perhaps with a low-impact exercise class.

If you're nursing, don't worry – exercise won't affect your ability to breastfeed or the composition of your breast milk. For your own comfort, though, you might want to pump or feed your baby before high-impact activities such as running, and wear a bra that provides plenty of support.

You can also involve your baby in your new workout routine. Put him or her in a stroller or baby carrier when you go for a walk, or in a baby seat or crib to watch you doing stretches or strengthening exercises. You may want to look for a gym that has a nursery so you can work out while your baby is supervised close by.

Find ways to fit exercise into your busy life. Consider workout DVDs you can use when your baby is playing or sleeping. If you drive to work, park a little farther from the office and squeeze in some walking, or look into a lunch-hour program at a nearby gym. If you pick something that's simple and convenient, you'll be more likely to stick with it.

Don't be too hard on yourself, though. While it's healthy to care about your body, getting in shape takes time and energy that may be in short supply these days. You'll undo all the great mental benefits of exercise if you stress too much about your appearance or how often you're working out. Your body did an amazing thing when it created your baby – give it some credit!
