Maximum Heart Rate (MHR)for someone of your age. To determine the effective heart rate range for

For someone who is 40 years old their
target heart rate zone is calculated:

220 – 40 = 180 (maximum heart rate)
180 x .6 = 108 beats per minute  

 SJQE\MQYQ

180 X .8 = 144 beats per minute  

 SJQE\MQYQ

So for a 40 year old the training zone would be 108 
to 144 beats per minute.

If you enter your age during programming the  
console will perform this calculation automatically. 
Entering your age is used for the Heart Rate programs. After calculating your MHR you can decide upon 
which goal you would like to pursue.

With all Spirit Fitness Heart Rate programs treadmills you may use the heart rate monitor feature without 
using the Heart Rate program. This function can be used during manual mode or during any of the seven 
different programs. The Heart Rate program automatically controls elevation to keep you at your desired
