Train with precision

Your six personalised zones appear instantly, colour-coded and ready to use with any heart rate monitor.

The Six Training Zones

Developed with sports scientist Joe Beer β€” each zone has a clear physiological purpose.

AR
Active Recovery
Very light effort β€” keeps blood moving without stress
~50–60% max
1
Extensive Aerobic
The foundation of endurance β€” long, comfortable efforts
~60–70% max
IA
Intensive Aerobic
Steady-state aerobic development; harder but still aerobic
~70–80% max
2a
Progressive Anaerobic
Approaching threshold β€” typical for sportives and Ironman races
~80–85% max
2b
Anaerobic Threshold
Lactate threshold effort β€” race pace for 1-hour events
~85–92% max
3
HIIT / Lactate Accumulation
High-intensity intervals β€” significant carbohydrate use
92–100% max

Exact BPM ranges are calculated from your personal test data β€” not a one-size-fits-all formula.
