Feasibility of an Activity Regimen in Patients With Advanced Stage Lung Cancer

The investigators will evaluate the feasibility of implementing a low-intensity, patient-centered activity regimen (PCAR) that prioritizes education and communication over a 12-week period in advanced stage lung cancer patients. The primary outcomes will include number of patients increasing their overall step count over the study period and adherence to step count recommendations. Secondary outcomes will include quality of life (QoL), dyspnea, and depression scores before and after the intervention as well as a patient feedback questionnaire (to guide further interventions). The goals are to increase overall step count and obtain adherence of \>50% of participants. The investigators will also assess whether the physical activity regimen influences markers of inflammation and glucose control and novel markers of cancer.
