The lesson during this first phase of your newborn's life is that exercise should not be at the top of your priority list. Squeeze in a slow to moderate walk when you can, but focus more on getting to know your baby and getting to know your spouse in his or her new role. Get plenty of rest and eat well. Before you know it, this special time with your newborn will be a distant memory. Relish it now.
Exercise is just around the corner.
Soon, your baby will begin to sleep for longer blocks of time and at more regular intervals. Now is the time to mark your return to fitness with an exercise plan. Work with your spouse to plan an equitable schedule with one of you watching the baby while the other gets in 30 minutes to an hour of activity. If you used to work out together, determine who among family and friends visits regularly. Most likely, they would love to take care of your baby for an hour or so while both of you log some exercise time.
