Arm Intervention/treatment
Experimental: Physical Activity Intervention
Patients will be allocated to a physical activity intervention to be performed 3-5 days per week
Behavioral: Monitored, At-Home Exercise Intervention
Patients will be enrolled in the BurnAlong program as well as receive FitBit heart rate + activity monitors to track adherence rates to the prescribed exercise regimen on BurnAlong, with subsequent motivational interventions triggered if compliance varies from prescription

No Intervention: Control
Patients will receive standard counseling regarding activity recommendations in pregnancy

Primary Outcome Measures :
  1. Adherence rate [ Time Frame: 20 weeks ]
    Total number of performed exercise sessions divided by prescribed exercise sessions (3 per week at minimum)

Secondary Outcome Measures :
  1. Gestational Diabetes [ Time Frame: 20 weeks ]
    Development of Gestational diabetes as determined by routine 1 hour and then subsequent 3 hour glucose testing results

  2. Maternal Weight Gain [ Time Frame: 20 weeks ]
    measured in kilograms

  3. Gestational age at delivery [ Time Frame: One year ]
    Infant's gestational age at delivery

  4. Rate of Cesarean delivery [ Time Frame: One year ]
    measured as the number of cesarean deliveries per total number of deliveries

  5. Infant weight [ Time Frame: One year ]
    Infant weight in grams measured post delivery

  6. Neonatal Apgar scores [ Time Frame: 1, 5, and 10 minutes of neonatal life ]
    An assessment of neonatal wellbeing measured at 1, 5, and 10 minutes post-delivery, and is measured on a scale of 0-9, with 9 being the highest, and 0 being the lowest.

  7. Neonatal Intensive Care Unit (NICU) Admission Rate [ Time Frame: One year ]
    Rate of admission of infants post-delivery to the NICU

  8. Neonatal hypoglycemia rates [ Time Frame: One year ]
    Number of infants with hypoglycemia divided by the total number of delivered infants
