Precision Calculation for your Heart Rate Training Zones
Hint: This is about a million times more accurate that that junky chart on the eliptical trainer.
Determine the rate at which you are going to do your cardio:
First determine your Resting Heart Rate.
This is most accurately accomplished by taking your pulse for 1 full minute first thing in the morning, before you even get out of bed. Double check it by taking a 15 sec pulse and then multiplying by 4.
Now plug your RHR, or Resting Heart Rate, into this formula.
220 – Age – RHR x % + RHR = Target Heart Rate
