Interval training on a smart trainer: structured and controlled sessions

An indoor trainer is an excellent place for intervals. Traffic lights, descents and road conditions cannot interrupt the effort. With a smart trainer and the right app, work and recovery can be controlled clearly.

What defines an interval session?

Interval training alternates between planned work and recovery. Depending on the goal, efforts may be short and very intense or longer and controlled. FTP-based targets adjust the workload to your current ability.

KOMRIDER shows duration, target zone and current power throughout the session. In ERG mode, the app controls resistance automatically. The intended training load stays consistent even when concentration starts to fade.

A simple structure for beginners

Start with an easy warm-up. The main set should contain a manageable number of well-executed repetitions. Pedal easily between efforts so you can begin the next interval under control. Finish with a cooldown.

A clear session is better than a complicated one. Three longer controlled efforts often provide more quality than many repetitions that fall apart before the end.

Cadence and cooling matter

Use a steady cadence in ERG mode. Increase cadence slightly before a higher power step begins. This helps prevent a stall and the rapid rise in resistance known as the ERG spiral.

There is no cooling airflow indoors. A strong fan, enough fluid and a towel are essential parts of the setup. Better cooling makes power more repeatable and helps preserve the quality of later intervals.

Progress one element at a time

Do not increase duration, intensity and repetition count together. Change one element, then observe how well you complete the workout. Include easy days and stop if you experience pain, dizziness or unusual symptoms.

Consistent, appropriate intervals are more useful than isolated extreme sessions. KOMRIDER supports this approach with a workout catalogue, training plans and a generator for custom sessions.
