Zone 3 Training
Tempo heart rate zone (70-80% max HR) that improves lactate clearance and sustained effort - the intensity most HYROX® athletes race at.
Zone 4 Training
Threshold heart rate zone (80-90% max HR) where lactate accumulates faster than the body can clear it - used for interval training and HYROX® station bursts.
Zone 5 Training
Maximum-effort heart rate zone (90-100% max HR) that develops VO2max and anaerobic power - used sparingly for sprint finishes and all-out HYROX® efforts.
