?How to use the NASM Cardio Routines?

Ok this may seem complicated but I assure you it is not. When you open any one of the listed in the “Training Tools“ you will see 3 zones of heart rate training.
Zone 1: 60-75% of MHR
Zone 2: 80-85% of MHR
Zone 3: 86-90% of MHR
MHR is short for Maximum Heart Rate.
MHR = 220 – Age
This means if you are 40 years of age you MHR = 180. Now inorder for you to figure out your zones you multiply your MHR by the percentages listed in the zones.
Zone 1: .6 * 180 = 108 & .75 * 180 = 135
Zone 2: .8 * 180 = 144 & .85 * 180 = 153
Zone 3: .86 * 180 = 155 & .9 * 180 = 162
So lets say you are 40 years of age and we are following Cycle 5. Go ahead and open it by selecting the link. Look at the “High Intensity Day” you will notice all three zones are in use.
- When your in zone 1 during the 5 minuite warm up you will keep your HR between 108 and 135.
- When your in zone 2 you will keep your HR between 144 and 153
- When your in zone 3 you will keep your HR between 155 and 162
