What this workout is for

Training Goal:

Introduction to HIIT training.

At its core, this is high-intensity focus for cycling. The structure matters more than the title: duration, recoveries, and intensity changes decide whether the session builds base, threshold control, or a harder top-end stimulus.

Workout structure

The chart is rendered from the stored workout data. Wider sections last longer, and taller blocks indicate higher target intensity.

10 min @ 60% | Ramp from 60% to 85% | 8x 1 min on / 1 min easy | 5 min @ 60% | 8x 1 min on / 1 min easy | 5 min @ 60% + 2 more steps

Training effect

The main stimulus sits in the hard sections. Sessions like this improve VO2max, anaerobic tolerance, and the ability to repeat demanding efforts without losing form.

How to execute it

Ride the easy sections with discipline and use power or heart rate as the guardrail. For structured indoor sessions, ERG mode works well as long as FTP and zones are current.

Where it fits in the week

Place this workout with an easy day before or after it. In a normal week, one session like this is often enough, especially if long endurance or strength work is also planned.

Watch especially for

  • Do not make the easy parts too hard.
  • Update zones before the session if your fitness has changed.
  • Review whether the intended stimulus was achieved, not only the averages.
