Anaerobic
Exercise 78-90%
Generates speed and
power. It works at or
above the body’s oxygen
intake capability, builds
muscle, and cannot be
maintained for a long
period of time.
The upper and lower heart rate limits are calculated by
multiplying your MHR by the percentages of the selected
training zone.
For example:
A 40-year-old training for basic health maintenance:
• His Upper Heart Rate Limit [220 - 40(age)] x 78%
• His Lower Heart Rate Limit [220 - 40(age)] x 65%
IMPORTANT Always warm up before exercise and
select the training zone that best suits your physique.
Exercise regularly, 20 to 30 minutes per session, three
to four times a week for a healthier cardiovascular
system.
WARNING Determining your individual training zone is
a critical step in the process towards an efficient and safe
training program. Please consult your doctor or health
professional to help you determine exercise frequency
and duration appropriate for your age, condition and
specific goals.
