It's not surprising that for many new moms, exercise often gets set aside by other priorities such as sleep, but daily exercise actually gives you more energy, not less. To lose, or "burn" fat, you'll want to do some form of aerobic exercise: fast-paced movements using large muscle groups that elevate your heart rate. With choices that range from walking or running to swimming or biking, there's a type of aerobic exercise for everyone, at every level of coordination.
A good goal is 20 to 40 minutes of aerobic exercise three to five times a week. If you weren't active during your pregnancy, start gradually. If you tapered off your fitness routine as your pregnancy progressed, begin at that modified level, and increase the intensity or time as you feel ready.
In combination with an aerobic workout, strength training also helps speed up your postpregnancy weight loss. Although most yoga routines aren't fast-paced enough to raise your heart rate to a fat-burning level, yoga classes can stretch your muscles and ease your mind, as well as improve your posture. In addition, as a mom who exercises, you'll be providing a great role model for your child. The key to exercise is finding an activity that fits in with your schedule and lifestyle -- and that you enjoy -- and then sticking with it.
