HRC Workout - INTERVAL HR
For an INTERVAL HR workout the user shall first enter their Age, Lower HR limit, and UP
-
PER HR limit for the workout. The initial values for the Lower HR and Upper HR limits are
determined based on the following formulas:
LOWER HR
= (220 - AGE) x 0.6
UPPER HR
= (220 - AGE) x 0.8
The above equation essentially states that the suggested lower heart rate limit is 60% of the
user’s suggested maximal heart rate and the suggested upper heart rate limit is 80% of the
user’s suggested maximal heart rate.
As an example, for a 40 year old, the suggested LOWER HR limit is (220-40) x 60% or 180
x 0.6 or 108 BPM and the suggested UPPER HR limit is (220-40) x 80% or 180 x 0.8 or 144
BPM. Note that when the entry for AGE is changed, the displayed LOWER HR and UPPER
HR limits also changes based on the equations defined above. Should the user want to in
-
crease or decrease either the suggested LOWER HR or UPPER HR values they can do so
simply by using the applicable PLUS or MINUS buttons to adjust.
Once the AGE and LOWER HR values have been entered, press the NEXT button.
