Build workouts that actually match how you train.

Structured workout planning means designing sessions with specific intervals, power zones, heart rate targets, and rest periods — rather than just logging what you did. Fitter lets you build these structured workouts and sync them directly to your device.

Fitter is built for cyclists who train with power and heart rate zones. You can create interval workouts with nested repeats, cadence targets, and power zones, then push them to Wahoo or export FIT files for Garmin and Zwift.

With Fitter's interval builder, you create work and rest blocks with specific targets (power, heart rate, cadence), nest them into repeat groups, and arrange them into a full session with warm-up and cool-down. Or ask the AI coach to generate one for you.

Yes. Fitter syncs structured workouts directly to Wahoo devices over Bluetooth, imports rowing data from Concept2 Logbook, and exports standard FIT files for Garmin and Zwift. Completed workouts sync back via Strava and Polar.

Tell the AI coach what you're training for — a race, a fitness goal, or a specific session type — and it generates a structured workout with warm-up, intervals, and cool-down tailored to your targets and training history.
