TARGET HEART RATE ZONES
Minimum / maximum target heart rates applicable to every
age are called the “target heart rate zones”.
Formula: max HR = 220 – age.
Maximum heart rate, or max HR, is the highest number of
heartbeats per minute (bpm) in an all-out effort. Training
intensities can be expressed as percentages of max HR.
With your personal physiological data properly set (Refer to
Page 10) first, the heart rate percentage is automatically
calculated by the system and the real-time heart rate
percentage is indicated during exercise.
HARD
Benefits: Maximizes performance capacity.
Recommended for: Fit persons and for short exercise sessions.
MODERATE
Benefits: Improves aerobic fitness.
Recommended for: Everybody, for sessions of moderate length.
LIGHT
Benefits: Manages weight and general wellness.
Recommended for: Everybody, for longer sessions.
Subject to training requirements, there are three different
exercise zones: Hard, Moderate, and Light.
