The Strength Running Podcast

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 [email protected]. 
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.

Sam Alexander is the head coach of the men's cross country and track & field teams at Connecticut College (Jason's alma mater!). Sam recently coached the track team to a historically high finish at the New England championships and helped the cross country team qualify for the National Championships for only the second time in program history. 
This episode focuses on development - or, how to progress through beginner to advanced stages of running. We discuss:
Athletic development for college runners vs. new runners
The "order of operations" of development
How to build speed and mitigate injury risk
"Fundamental" workouts that build specific skills
Talking to college coaches is always educational because these are the operators, those in the trenches with athletes every day in high-stakes, performance-driven environments. We can learn a lot from Sam!

In this episode, former WR holder and current AR holder Zach Bitter joins us to discuss how he navigates failure, what led to his DNF at his recent 100-mile record attempt, his experiments with fueling and carbs, and a lot more.

Thank you Gut & Green!
Previnex's new Gut & Green Superfoods powder is my new go-to. It has organic barley and oat grass, alfalfa, spirulina, chlorella, kale and broccoli… and that's it. Simplicity is powerful and Gut & Green delivers on what I care most about: doing one thing really well.
Their ingredients are backed by clinical data and contain three specific gut fibers that help promote GI health, digestion, reduced inflammation, and a better microbiome. As someone who doesn't always eat all of their vegetables, this is important to me.
With twice of the fiber of my last greens mix and a better flavor, it's a no brainer. Gut & Green Superfoods is like insurance against my diet (which isn't always as good as it should be) so I can feel my best throughout the day.
Try it for yourself here at previnex.com and be sure to use code "JASONGREENS" to save 15% off your first order. Don't tell anyone, but if you put Gut & Green Superfoods powder in your cart, then the 15% off discount will work for anything else you add into your cart as well. Thanks Gut & Green!

After resisting most supplements for the better part of my life, I'm cautiously changing my tune. I'm now a Masters runner and in my personal life, I'm optimizing for longevity. I want to be my healthiest self for as long as possible and I'm excited to partner with Previnex to make that happen.
Previnex uses the most bioavailable, clinically tested ingredients, the optimal form and dose of each ingredient, pharmaceutical grade manufacturing, testing of raw ingredients and finished products. For every purchase you make, they also donate vitamins to kids in need.
Their new Muscle Health Plus is something I'm now taking. Turning 40 – and having a thin frame – has made me realize that I need to prioritize lean muscle mass to stay healthy and age well. Muscle Health Plus has creatine, essential and branched chain amino acids, and it's designed in a way to maximize protein synthesis and the absorption of amino acids.
Muscle Health Plus will help you prevent muscle damage, which is particularly important for aging runners who want to protect themselves from muscle loss and recover faster after hard workouts. As is true for all of their products, Previnex adheres to the highest of standards: their ingredients are clinically proven to do what they say they're going to do.
They're now offering international shipping so if you live in the UK, Canada, Australia, or anywhere around the world, you can try Previnex as well.
Previnex offers a 30-day money back guarantee. If you don't feel the benefits of their product, you get your money back no questions asked. With their focus on quality and customer satisfaction, I hope you'll try it!

So, what exactly is "training?" Is it different than "exercise?"
In this episode, we discuss what training specifically is, what it's not, and what it's attempting to do. Once you understand that we're after change in our bodies, we can better structure training to reach our goals.
