Milo’s six heart rate zones

• Zone 1: Recovery

  Very easy effort for warm-ups, cool-downs, and recovery.

• Zone 2: Easy

  Comfortable, all-day pace where most endurance is built.

• Zone 3: Tempo / Marathon

  “Comfortably hard” effort for improving stamina.

• Zone 4: Threshold

  Hard pace you can hold for about an hour. Boosts your lactate threshold.

• Zone 5: VO2 Max

  Very hard intervals that improve your aerobic engine.

• Zone 6: Max Effort / Power

  Short, nearly all-out bursts for top-end speed and neuromuscular power.
