Dr. Andrew Best is a professor at the Massachusetts College of Liberal Arts where he focuses on evolutionary questions about human physiology. You can email him at andrew.best@mcla.edu. 

His latest study was titled "Ultra Endurance Athletes and the Metabolic Ceiling." They looked at the maximum, sustainable amount of energy expenditure that can be done over a long time period. It answers the question, "what is the limit of human energy expenditure?"

It's a metric that literally dictates how hard you can train. If you want sustainable performance, you'll love this episode.

Thank you MOBO Board!

Invented by renowned physical therapist Jay Dicharry, MOBO helps you stabilize your stance with an innovative rocker board that's set up on two fins. The design effectively forces you to drive your big toe into the board to improve your stability. I was pretty arrogant going into my first session on the MOBO Board. How hard can it be to balance, right? Well, I was humbled pretty quickly!

Even if you're a good runner, better balance, stability, and proprioception is going to help you have a more powerful stride and prevent more running injuries. You'll learn how to improve the efficiency of the kinetic chain from your hip to your big toe. Because as Jay likes to say, it's not just how strong you are, but how well you use that strength.

I was recently at a weekend physical therapy workshop (lol I was the only running coach) and learned how important (and rare) this simple movement is. Save 10% with code STRENGTHRUN10 at checkout at moboboard.com.
