In this episode, Dr. Moose Herrring and Dr. Rob Green have a lively discussion on trainning zones and the confusion they can create for many.   Do you use HR?  Do you use Pace or Power?  Do you use perceived exertion?In the end, we expose that one metric is not the end all, be all.  They all have advantages and disadvatages.   We also cover how to do field tests at home to find your anaerobic threshold pace, power and lactate threshold heart rates.   Enjoy HUB Life!
