In teams of two, complete as many rounds and reps as possible in 30 minutes of:
Run 400 Meters
15 Air Squats
Only one person may be running at a time. While one partner runs, the partner inside the box should be working through as many rounds as possible of “Cindy” (5 pull-ups, 10 push-ups and 15 air squats). Partners then switch roles once the running partner has returned.
