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.

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.

Thanks to Chafed & Cranky Coffee!

If you know me personally or watch our YouTube videos, you know that I love caffeine and coffee in particular. We all know the performance benefits of caffeine at this point: it's the world's most studied drug and is the most effective, legal performance enhancing drug on the market for runners. If you're not supplementing with caffeine before and during your big races, you're missing out on faster finishing times.

Chafed & Cranky is a quirky brand that I love. But despite the fun branding, it's a high quality product with a variety of organic, fair trade, and single origin roasts to choose from. Because I like to be on brand, I go for a light roast since it has a higher caffeine content and I grind the beans fresh for my personal French Press in the morning.
