• Post-operative physical activity as measured by an accelerometer. [ Time Frame: Baseline to 12 months post-surgery ]
  Post-operative physical activity will be calculated as the time spent in different intensities of physical activity over a period of 7 days as measured by accelerometer
• Physical function as measured by the Patient Reported Outcomes Measurement Information System (PROMIS) - Physical Function Domain [ Time Frame: Baseline to 12 months post-surgery ]
  The PROMIS Physical Function 4-item short form will be used to measure physical function. Each item is measured from 1 to 5, representing low to high physical function, respectively. Total score ranges from 4 to 20. Total raw scores will be converted to T-scores.
• Disability as measured by the Oswestry Disability Index. [ Time Frame: Baseline to 12 months post-surgery ]
  The ODI has 10 items and scores range from 0 to 100%. A higher score represents higher disability.
• Back pain as measured by the Numeric Rating Scale (NRS). [ Time Frame: Baseline to 12 months post-surgery ]
  The NRS has 1 item and scores range from 0 to 10. A higher score represents more back pain.
• Leg pain as measured by the Numeric Rating Scale (NRS). [ Time Frame: Baseline to 12 months post-surgery ]
  The NRS has 1 item and scores range from 0 to 10. A higher score represents more leg pain.
• Opioid Use as measured by patient self-report. [ Time Frame: Baseline to 12 months post-surgery ]
  A single-item patient-reported opioid use question that ask about current opioid use.
• Depression as measured by the Patient Reported Outcomes Measurement Information System (PROMIS) - Depression Domain [ Time Frame: Baseline to 12 months post-surgery ]
  Depression 4-item short form will be used to measure depression. Responses for each item vary from Never, Rarely, Sometimes, Often, and Always. The lowest score is 4 and the highest score is 20, with higher scores indicating greater severity of depression.Total raw scores will be converted to T-scores.
• Pain self-efficacy as measured by the Pain Self-Efficacy Questionnaire (PSEQ) [ Time Frame: Baseline to 12 months post-surgery ]
  PSEQ has 10 items and responses vary from Not at all confident to completely confident. The lowest score is 0 and the highest score is 60 with a higher score representing higher pain self-efficacy.
• Fear of movement as measured by theTampa Scale of Kinesiophobia. [ Time Frame: Baseline to 12 months post-surgery ]
  The 17-item Tampa Scale of Kinesiophobia will be used to measure fear of movement. It has two sub-scales (activity avoidance and fear of pain) and the total score ranges from 17 to 68 with higher scores indicating greater fear of movement.

• Behavioral: Physical activity intervention
  Participants randomized to the physical activity intervention will receive a Fitbit and be enrolled in Fitabase (Fitbit tracking system). Participants will also participate in 8 tele-health sessions with a physical therapist. Sessions will involve setting weekly physical activity goals and reviewing the participant's physical activity on the Fitbit tracking system.
• Other: Usual care
  Usual postoperative care includes surgeon-directed lifting restrictions, advice to stay active, and oral analgesics as needed. Physical therapy referral will be at the discretion of the surgeon. However, physical therapy is not typically started until 12 weeks after surgery.

• Experimental: Physical Activity
  Participants randomized to the physical activity intervention will receive usual postoperative care and a tele-health physical activity intervention.
  Intervention: Behavioral: Physical activity intervention
• Usual Care
  Participants randomized to usual care will receive postoperative care as determined by their treating surgeon.
  Intervention: Other: Usual care
