If you're trying to stay in the fitness habit during your pregnancy, a well-chosen fitness routine that you can do in the comfort of your own home can make it much easier to keep your new commitments. It can also come in handy after you've had a baby, when it's not as easy to go for a fitness walk or to an exercise class with your baby in tow. You should try to formalize a great routine now and also use it after the baby is born.
First, find a good spot in your house that may inspire you to work out whenever you have some free time. Maybe some place near the TV so you can catch up on your favorite shows and work out at the same time. You might also want to opt for an exercise video or even some home equipment like a treadmill or elliptical trainer. Although the latter can be a serious investment, the cost is often no more than that of a one-year gym membership, a swim card for the local pool, or a year's worth of drop-in aerobic classes. Plus, you won't have a built-in excuse not to exercise when the weather is bad or you can't find a sitter.
