Heart Rate Monitoring - LifeSpan C5i Owner's Manual

Heart Rate Monitoring

Zone 5 — Performance Redline Zone: 90% - 100% of your Max HR
The performance zone involves extreme effort, requiring the heart to beat
at or near maximum capacity. Training bouts include intense incline or
sprinting, benefiting speed, power, and anaerobic performance competency.
Zone 4 — Threshold Zone: 80% - 90% of your Max HR
The threshold zone involves intense jogging or sub-maximal sprinting,
typically unsustainable for long periods of time. Benefits include highly-
elevated calorie burn, speed and power performance enhancement,
improved lactate removal capabilities, and enriched heart health.
Zone 3 — Aerobic Zone: 70% - 80% of your Max HR
The aerobic zone is ideal for cardiovascular training. Workouts in this zone
are more intense, involving moderate jogging. Long-term benefits are
improved heart health and cardiovascular performance, reductions in blood
pressure and cholesterol, and increased calorie burn.
Zone 2 — Temperate Zone: 60% - 70% of your Max HR
The temperate zone consists of moderate-intensity exercise, typically as fast
walking to slow jogging. Speaking is more difficult and breathing is elevated.
Benefits are similar to those of the healthy heart rate zone, though caloric
expenditure is higher.
Zone 1 — Healthy Heart Zone: 50% - 60% of your Max HR
The healthy heart zone involves safe, low-intensity activity, like medium-
to-brisk walking. Full conversations can be held, despite a gentle increase
in respiration. Benefits include reduced risk of heart and vascular disease,
moderated blood pressure and cholesterol, and improved insulin sensitivity.
