Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this intervention is to help new mothers who had elevated blood pressure during pregnancy become more physically active after birth. The investigators will connect data from FitBits to the electronic health record. Women will then get weekly messages with feedback and goals to help them stay active. The investigators will test if the intervention improves step counts and blood pressure after pregnancy. The investigators will also test if the intervention is feasible and enjoyed by postpartum women.
