Active_comparator: Arm I (usual care)

Patients receive usual care consisting of the clinician educating the patient on the importance of increasing exercise activity in the preoperative period and early ambulation in the postoperative setting.

Active_comparator: Arm II (usual care, Fitbit)

Patients receive usual care consisting of the clinician educating the patient on the importance of increasing exercise activity in the preoperative period and early ambulation in the postoperative setting. Patients also receive a Fitbit to monitor step count

Experimental: Arm III (usual care, Fitbit, Fitbit app)

Patients receive usual care consisting of the clinician educating the patient on the importance of increasing exercise activity in the preoperative period and walking in the postoperative setting. Patients also receive a Fitbit device, install and use the Fitbit app on a smartphone. Postoperative step goals are as follows: Postoperative day (POD) 1: 25% of baseline. Subsequent days will be increased by 10% until patient reaches baseline daily step number. Five automatic daily reminders (delivered by the Fitbit Inspire HR\^TM device itself) to meet a minimum of 250 steps an hour. Postoperatively, patients will be invited to participate in a private group with a leaderboard that consists of step numbers of other participants in the study in an anonymous fashion.
