session load
A simple measure of how hard a training session was: effort rating (0 to 10) × minutes.
weekly load
The total of all session loads in a week.
heart-rate recovery
How much your heart rate drops in the first minute after you stop hard exercise. A bigger drop usually means better cardiorespiratory fitness.
benchmark
A repeatable task you measure inside your normal activity (for example, laps of a set route) to compare over time.
moving average
The average of the last few results (for example, the last 3), recalculated each time, which smooths out random ups and downs.
training log
A record of each session: what you did, how long, how hard, and how you felt.
