Light
Exercising in the Light* intensity zone (60-70% HR
max
) is good for improving health and fitness. It also improves basic endurance and
helps you to recover from heavier exercise.
Moderate
Exercising in the Moderate intensity zone (70-80% HR
max
) is effective particularly for improving aerobic fitness. All programs include
exercise in this intensity zone.
Hard
The Hard intensity zone (80-90% HR
max
) is for relatively short exercise at high intensity. Exercising in this zone causes heavy breathing,
muscle tiredness, and fatigue. It increases maximum performance capacity. Only Improve and Maximize Programs include exercise in this
intensity zone.
