Target Training Zone (TTZ)

To achieve the real benefits of an aerobic workout and overall fitness, your core workout should raise your heart rate to your target training zone.

Calculate Your TTZ here:

Enter Your Age
Enter Your Resting Heart Rate
Don't Know RHR
Your MHR is  
Your TTZ is



The formula for exact calculation of TTZ:
TTZ = Training Range % + Resting Heart Rate
Training Range % = (Heart Rate Reserve) x (60% to 80%)
Heart Rate Reserve = MHR - Resting Heart Rate

The formula for quick calculation of TTZ:
TTZ = 70% to 80% of MHR
Eg.: If your MHR is 190, then your TTZ is between 133 to 152

You can also refer the chart below to find out the TTZ for various ages. Draw a vertical line starting from your age found in the horizontal line below. The two nos. that cross at the lower and upper limits of green zone will give you the TTZ.
