When can I safely exercise again?

If you had a healthy pregnancy and a normal vaginal delivery, the answer may be sooner than you thought. You can start exercising within a few days of delivery if you feel ready, according to the American College of Obstetricians and Gynecologists.

That doesn't mean picking up where you left off in your favorite boot camp class, though. Walking is a great start for many women. That could be a 10-minute stroll around the block, with or without your baby. Build up as you feel able, aiming for 20 to 30 minutes a day.

By six weeks postpartum, getting 150 minutes of exercise a week is a good goal, just like for all adults.

Moms who had complications or delivered by C-section may need to take it more slowly. A doctor, midwife or physical therapist can give personalized advice.
