How to track your Heart Rate during exercise:
Take wrist pulse for 6 seconds and multiply by 10.
Here's how to figure your 'Target' heart rate:
220 minus your age = [A]
[A] = Maximum heart rate
70% = Ideal Fat Burning Heart Rate ([A] X .70)
40% = Resting Heart Rate ([A] x .40)
To get the most effective results from this routine, modify your intensity level to train within your target fat burning heart rate (70%).
