I’ve been doing metabolic testing and VO2max testing for a fair amount of time now, but mostly with predictable results. Not until recently, have we been testing for than one type of runner, and boy have results not been quite so “textbook.” These results have led me to explore more into the topic of metabolic efficiency.

This led to some personal revelations as to why certain runners struggle so much with not only training, but losing weight, and being able to progress from a health standpoint. I hope you find this info interesting and can put some of this towards your own training or coaching!
