YOUR TIME IS PRECIOUS; DON’T WASTE IT!



I’ve already written that LESS is MORE.  The key to successfully implementing the less is more principle is by cranking up the intensity. That’s because cardiovascular exercise relies on frequency, duration and intensity for effectiveness.  Both frequency and duration are about time, and none of us has enough time. So don’t waste it.  The only variable left is intensity.  So how do we increase the intensity?

Your heart rate is the best way to judge intensity:
The traditional formula (the latest formula takes into account a person’s resting heart rate and has results that vary slightly from the traditional formula presented here) used to calculate target heart rate zones is:
220 minus your age = 100% (maximum heart rate)

For example:  a 35 year old’s maximum heart rate is:
220 - 35 =  185.0


Many people who exercise regularly often workout at a moderate intensity level.  Moderate is defined as 60% - 70% of the maximum.  In our example the moderate range; 60% - 70% of the maximum 185.0 is 111 – 129.5.

A high intensity level falls between about 75 - 85% of your maximum heart rate.  At this level exercise feels challenging and leaves you too breathless to talk much.  For our 35 year old, this is a range of 139 – 157.
