To view your Cardio load status and Cardio load buildup in the Flow web service, go to Progress > Car-
dio Load report.
The red bars illustrate the cardio load from your training sessions. The higher the bar, the harder the
session was on your cardio system.
The background colors show how hard a session was compared to your session average from the past
90 days, just like the scale of five bullets and verbal descriptions (Very low, Low, Medium, High, Very
high).
Strain shows how much you have strained yourself with training lately. It shows your average daily car-
dio load from the past 7 days.
Tolerance describes how prepared you are to endure cardio training. It shows your average daily car-
dio load from the past 28 days. To improve your tolerance for cardio training, slowly increase your
training over a longer period of time.
