Power
CP (Critical Power)
The highest power you can sustain indefinitely from aerobic metabolism alone.
En savoir plusFTP (Functional Threshold Power)
The highest power, in watts, you can sustain for roughly an hour.
En savoir plusNP (Normalized Power)
A weighted average of power that reflects the physiological cost of a variable-intensity ride.
En savoir plusSweet Spot
Training intensity at roughly 88–94% of FTP — high productivity per unit of fatigue.
En savoir plusThreshold
Intensity at or around FTP/LTHR — the boundary between sustainable and unsustainable effort.
En savoir plusVO2 max
The maximum volume of oxygen your body can consume and use during intense exercise.
En savoir plusW' (W-prime)
The amount of work, in kilojoules, you can do above Critical Power before exhaustion.
En savoir plusHeart rate
Training load
ATL (Acute Training Load)
A 7-day weighted average of your daily training stress — a proxy for fatigue.
En savoir plusCTL (Chronic Training Load)
A 42-day weighted average of your daily training stress — a proxy for fitness.
En savoir plusIF (Intensity Factor)
A workout's Normalized Power divided by your FTP — a simple measure of how hard the ride was relative to threshold.
En savoir plusTSB (Training Stress Balance)
CTL minus ATL — a single number that estimates how fresh or fatigued you are.
En savoir plusTSS (Training Stress Score)
A single number summarizing how much physiological stress a workout produced, scaled to FTP.
En savoir plusPace & effort
Cadence
How many times your legs complete a full pedal stroke per minute (cycling) or steps per minute (running).
En savoir plusNegative split
Completing the second half of an effort or race faster than the first.
En savoir plusZone 2
Easy endurance riding at 55–75% of FTP — the foundation of aerobic fitness.
