How about this as a format for session_plan (written in Pseudo-JSON)

session_plan:
  session_plan_exercises:
   [
      {
       number_in_set: int
       position: int
       station: Station (if locked to one)
       exercise: Exercise (no adjustments)

  phase: string
  position: int
  session_plan_exercises:
