Target Heart Rate.....Why Not?

We have all heard about the use of Target Heart Rate(THR) in exercise programs, however only a select few actually utilize it.
For those of you who do not know how to calculate your THR here is the procedure:

• 220 - AGE = MHR / Max Heart Rate      ( Eg: 220 - 32 = 188 )
• You will need to take your Resting Heart Rate / RHR (Eg: 62)
• Then you subtract your RHR from your MHR = your HRR / Heart Rate Reserve (Eg:188-62=126)
• To get your Low Range THR Take your (HRR x .5 [50%]) + RHR = LHR (Eg:(126 x .5) + 62 =125
• To get your High Range THR take your (HRR x .85 [85%]) + RHR = HHR (Eg:(126x.85)+62=169
• Thus making your THR 125 bpm - 169 bpm

Now that we are all on the same page, back to the question at hand. Myself I feel it is very beneficial to utilize your THR, heart rate being your internal intensity scale why wouldn't you use it. Using your HR appropriately will strengthen your heart aiding in better circulation and respiration in the end aiding you efficiently to get you to your goals.

Understandably this is only my opinion, if you have any discrepancies or arguments to this please comment
