Polarised Training

Polarised Training: Polarised training is a training philosophy where approximately 80% of volume is at low intensity (UT2) and 20% at high intensity, with minimal time in the moderate threshold zone.

What is Polarised Training?

Polarised training is the dominant training model in elite rowing and endurance sport. The principle is simple: most training should be genuinely easy (UT2), and the remaining hard sessions should be genuinely hard (AT/TR/AN). The moderate "grey zone" between easy and hard (UT1/threshold) should make up only a small fraction of total volume. Research consistently shows that polarised training produces better endurance adaptations than threshold-focused or evenly distributed training. The reason: easy training develops the aerobic base without accumulated fatigue, while hard sessions provide the high-intensity stimulus needed for VO2 max and speed development. The grey zone provides a moderate stimulus but creates disproportionate fatigue.

How Watta Uses Polarised Training

Watta's Effort Score helps enforce polarised training. By tracking each session's score and zone (Recovery, Building, Training, Peak), you can verify that the majority of your sessions fall in the Recovery/Building zones (easy) with targeted sessions in Training/Peak zones (hard). If most sessions cluster in the "Building" zone, you may be training too hard on easy days.
