Get in the swim. Working out in the water is wonderful for both of you. You'll enjoy feeling weightless after all those months of feeling huge, and she'll enjoy the simple act of splashing her tiny hands. And exercising with baby in the water is simple — you can use your baby as a weight by holding her beneath the arms and lifting her up, then lowering her back into the pool; or, get a pint-sized "boat" (make sure it's safe) she can float in while you do your thing next to her.
Of course you want to get back into shape — and of course, finding time to work out can be next to impossible with junior (adorably) monopolizing your time. One way to get back into the fitness swing is to start exercising with baby. Here, some simple ideas on moving your butt (and whittling down your belly) with your little one at your side.
Join a "mommy and me" class. The ultimate in exercising with baby! Check your local Y or newspaper, or look online for classes in your neck of the woods.
While you exercise with baby, avoid forcing any poses or moves to prevent injury to you or your little exercise buddy. While exercise for mom offers many benefits, including reduction of anxiety, stress and likelihood of postpartum depression, the opportunity to bond when you exercise with your newborn is a bonus from which you both benefit.
