After Sarah Corcoran gave birth to her first child, a son, Benjamjin, she joined fitness classes designed for moms *and* their babies. She returned to her pre-pregnancy weight.
"I really enjoy being able to work out with him," says Sarah Corcoran.
Instructor Kathleen Donahoe says postnatal fitness is healthy for all new moms.
"Exercise post-baby is really important because it gets the mom back in shape and it is also great because it combats post-partum depression."
But Donahoe tells women that exercise alone won't make pregnancy pounds disappear.
"It's not a quick fix. You want to do it in a healthy way, you want to make sure you're eating enough, particularly if you're breastfeeding. I think a slow approach is best."
For women who had a condition during their pregnancy like gestational diabetes, or for those who had been on bed rest...
"It's especially important for these women to get out and exercise after they have their baby."
But moms should check with their doctor before starting any workout regimen.
As for Sarah, she cherishes the time she gets to spend with Benjamin at the classes.
"He really has a lot of fun doing this and its fun for me to watch him enjoy it so much."
