HIIT Cardio -‐‑ Overview
The higher your cardio fitness level the quicker your HR will drop during recovery
intervals. This is a great way to measure your cardio improvement progress as you
continue with this training.
For example, for your first few HIIT cardio sessions, it may take you 3 minutes to
bring your HR back down to 60% of MHR. A s you progress and increase your cardio
fitness levels it will eventually take you 2 minutes to properly recover and then 1
minute.
Most cardio equipment has a heart rate monitor built in to the handgrips. If your
equipment does not include this built in feature you can buy a HR monitor watch.
This watch will show you exactly where your heart rate is so you can properly stay
within the proper HR zone and increase/decrease intensity as needed.
