The study duration is 4 weeks long, during which subjects will undergo a 1 week run-in period followed by 3 randomized weeks of observational study. During the 1 week run-in period, subjects will familiarize themselves with the CGM and the other data collection procedures. Following the run-in week, the subject will be randomized to a specific order of observation weeks. The three observation weeks are a resistance training week, an aerobic exercise week and a control week with no explicit exercise. During the observation weeks, there will be 4 interventions planned, two during both the aerobic exercise and the resistance training week. See Schematic below for details. During both the aerobic exercise week intervention visits, subjects will exercise for ~45 minutes on a treadmill and during the resistance training week, subjects will perform strength training exercises for 1-3 sets per exercise at a weight that can be lifted for 8-12 repetitions (~60-80% of 1-repetition max). The duration of the resistance training period is expected to be ~45min. Subjects will continue to perform daily activities during each of the weeks.
