For the active month the chart provides a progressive comparison of the Number of Cardio workouts you planned using your AdLife Software Forecast tool versus the actual number of Cardio workouts you have done.
If you find that you are missing your targeted number of sessions you can balance this by extending the length of each session. This can help maintain your AdLife Points in the green while the session number may slip into the yellow.
It is however the best idea to keep the session number in the green as optimum benefit is gained with consistency.
