"Tissue tolerance" might be a hard term for the average runner to define. But it could also be how you prevent your next big running injury.

Phil Batterson, PhD, is a former competitive runner with a background in human bioenergetics.

As the founder of Critical Oxygen, he gives athletes and coaches knowledge, testing, and coaching to optimize their physiology and maximize endurance performance.

We talk about:

• How pliability, range of motion, and mobility affect tissue tolerance
• The impact of shock on the body while running
• Approaching training with injury prevention in mind
• Strength training and plyometrics to build tissue tolerance
• The role of cross training in injury prevention and adaptations
• How proteins help runners stay strong, but many aren't eating enough of it
• Hill training as a tool to improve tissue tolerance
• Why you don't need to barefoot run

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.

Treat yourself to delicious, high quality, performance benefitting coffee with Chafed & Cranky. Use code JASON at checkout to save 15% at chafedandcranky.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.

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! Use code jason15 for 15% off your first order at Previnex!
