Structured and adaptive workouts

A structured workout comes from the built-in library, an imported .zwo file, or the in-app workout builder. While it runs, your trainer holds each step's target power (ERG mode); the route underneath still drives the map, the distance and your world position.

The adaptive mode needs both a heart rate strap and a power source. It starts by finding out how fresh you are today, then adjusts every block's power target to how your body is responding.

The adaptive mode never lets your heart rate run away: if it climbs too high, power backs off until you recover.
