THE BRONX - Not all moms would say pregnancy is the key to weight loss, but one Bronx native is using her mommy status to shed the pounds.

Sherisse-Lee Lewis says she uses her son's stroller as a workout machine.

The stroller helps her run, do lunges and even crunches to lose 60 pounds in just nine months.

At her heaviest, the 5 foot 4 inches mom weighed 200 pounds.
