Zone 4 (80 to 90% of maximum heart rate):
●
Hard training
Zone 4 training improves speed endurance
and enhances the ability of the body to use
protein (sugar) for energy. In addition, Zone
4 training allows you to tolerate high levels
of lactic acid in the blood.
Zone 4 training results in muscle fatigue and
rough breathing.
Zone 5 (90 to 100% of maximum heart rate):
●
Very hard training
Zone 5 training improves maximum
performance. Large amounts of lactic acid
are accumulated, so long-term training is
not possible.
Zone 5 training results in labored breathing
and muscle fatigue.

If you engage in heart-rate training while the
heart rate zone alert is enabled, the watch will
perform a sound and/or vibration operation to
let you know when your current heart rate is
outside your target zone. If you do not re-enter
