Overweight and obese endometrial cancer (EC) survivors at the University of North Carolina (UNC) at Chapel Hill will be approached for tailored feedback fitness intervention. The investigators plan to enroll 36 women (18 in each arm) to evaluate if receipt of weekly tailored feedback messages can improve physical activity in EC survivors. It is hypothesized that women receiving the feedback message intervention will increase step counts from baseline more than 2,000 steps compared to women in the non-intervention arm.

Objectives:

• To assess if a tailored feedback fitness intervention can increase physical activity in EC survivors from baseline to 12 weeks post-baseline
• To determine the acceptability of the fitness intervention in EC survivors through a completion survey.
• To assess if a tailored feedback message fitness intervention can (1) decrease BMI, (2) reduce waitst to hip (W.H) ratios, (3) improve quality of life (QOL) and (4) improve serum metabolic markers (insulin, glucose and low density lipoprotein (LDL) in EC survivors.

Inclusion Criteria:

• Be over the age of 18 years
• Have a confirmed diagnosis of endometrial cancer and have completed therapy (surgery, chemotherapy or radiation) within the past 6 months
• Have no current evidence of endometrial cancer
• Have a BMI 25 kg/m2 or greater
• Have approval from their treating physician to engage in moderate-intensity physical activity.
• Have a smart phone with Bluetooth capabilities turned on
• Have access to email

Exclusion Criteria:

• Are currently undergoing treatment for their cancer
• Are unable to read a sample message aloud
• Do not have a computer or smart phone with Bluetooth capabilities
• Are pregnant
• Have a history of angina or palpitations with exertion
• Have a history of uncontrolled pulmonary disease (COPD or asthma)
• Have one or more significant medical conditions that in the physician's judgment preclude participation in the walking intervention.
