How are levels assigned to the workouts?

Levels are assigned to each workout in GlucoseZone based on the movements being performed and the challenge and intensity of those movements.  Level 1 workouts are light intensity designed for beginners, or people who are just getting started with physical activity.  Level 2 workouts are medium intensity, and designed for intermediates, or people that are ready to progress from Level 1.  Level 3 workouts are rigorous in intensity and designed for advanced challenges.  Some programs in GlucoseZone have Level 1, Level 2 and Level 3 workouts.  Other are only Level 1, or only Level 3.
