CARDIOSTRONG CST-TX40E Assembly And Operating Instructions Manual page 44

Example:
For a 45-year-old man or woman, the maximum heart rate is 175 (220 - 45 = 175).
• The fat burning target zone (55%) is at approximately 96 beats/min.
= (220 - age) x 0.55.
• The cardio target zone (75%) is at approximately 131 beats/min.
= (220 - age) x 0.75.
• The maximum heart rate for an anaerobic load training (90%) is at approximately
157 beats/min. = (220 - age) x 0.9.
