When runners get hurt, it’s often a tissue health problem, like a tendon injury. Jay Dicharry is a physical therapist, author, entrepreneur, and faculty member at Oregon State University who knows a lot about tissue health for runners. He’s written some of my favorite books on running performance and injury prevention, including “Anatomy for Runners” and “Running Rewired.” Jay also hosts workshops for physical therapists. In this episode, Jay and I talk about:  New research on tissue remodeling and load tolerance skills to develop durable runners Improving strength, bone density, and tendon health through specific exercises and training methods Debunking common beliefs around running and bone health Proper plyometric training for bone and tissue health The link between nutrition, bone health, and stress fractures Tendon health and repair through slow loading (including Achilles injuries) How to prevent and address tendon injuries in runners through sound strength training Why runner’s feet need special attention Using the MOBO Board as a diagnostic tool for fatigue Every runner can learn something about tissue health from Jay in this episode to help them run strong and stay injury-free.

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.

PT & MOBO Creator Jay Dicharry on Tissue Health: How to Strengthen Bones & Tendons

Runners ask all the time: How should I fit strength training into my endurance goals, and how can I get as strong as possible with limited time? Holly Martin is a personal fitness trainer and run coach based in Nashville, TN who specializes in time-efficient circuit training and individually tailored run programs. Holly comes from a diverse background of professional ballet, ultramarathon running, and 10 years of experience in CrossFit. She’s finished many ultra marathons, including two 100 milers. In this episode, Holly and I talk about:  Strength training for ultra runners to prevent injury and improve endurance Single leg work to reveal weaknesses, imbalances, and poor movement patterns Proper mechanics and activation of certain areas, particularly for runners with weak glutes or other imbalances Purposeful workouts over working out for appearance Strength training for trail runners, focusing on heavy lifts and single leg exercises Alternating between heavier weights and technical work like agility to improve power and explosiveness Quality over quantity in strength training while training for an ultra-marathon When to modify or cut back on strength training for runners based on hunger, fatigue, and form Matching strength training to current fitness level and adjusting as needed in the final two months before the race Enjoying the training process for an ultra-marathon, rather than solely focusing on numbers and metrics Avoiding technical or skill-based movements in the gym that don't directly benefit running Mobility work and static stretching for runners who experience tightness or muscle boundness after training  This is a must-listen episode for an ultra runner who knows they need to step up their strength training game in an approachable way.
