212: David Grey on Barefoot Dynamics, Foot Actions, and a Joint-Based Approach to Relieving Tendon Pain | Sponsored by SimpliFaster
Today’s episode features biomechanics specialist and rehabilitation expert, David Grey. David runs the Grey Injury Clinic and helps athletes with injury, pain, rehab, and performance. David has learned under a great number of mentors, and is influenced greatly by the work of Gary Ward who is a 2x previous podcast guest and the creator of the “Anatomy in Motion” system. David is also influenced by systems such as PRI and the martial arts.
Through his diverse studies and experience, David is able to get athletes and clients out of pain who have previously been through months of traditional therapy with limited results. He previously appeared on episode #160 of the podcast where he spoke on the link between pronation and using the glutes effectively.
In training and rehab, we so often look to exercises that strengthen, before we put a priority on biomechanics and joint actions. The problem is, that in treating pain, unless we fix the biomechanics, no matter how good the strength treatment was, the problem will eventually return. We know that in performance training, we want to build a “base of technique” because the way our body forms from a myo-fascial perspective as a season of training unfolds is going to be based on our technique. Bad technique can yield the result of muscles getting active and trained that shouldn’t, and other important muscle groups getting under-developed. By training the right joint motions, and getting the feet to work properly, we take a huge step in getting athletes to reaching their highest potential.
On the podcast today, David goes through a joint-based approach to working with those who have Achilles pain, and particularly, knee pain. He gets into the necessary co-contractions needed to help stabilize the knee joint, and why calcaneus mobility is important for both Achilles tendon and knee tendon injury prevention. We start out the talk with a chat on the feet, how barefoot training might not be all that it’s cracked up to be for some athletes, and the balance between pronation and supination of the foot in performance training. All this and more is in the latest podcast.

Timestamps and Main Points
5:00 The importance of supination in human movement and athletics, as well as why it is more important to think in terms of pronat-ing and supinat-ing rather than pronation and supination.
12:00 How sensation on the sole of the foot is essential for pronating properly and why simply walking around barefoot may not be truly helpful.
26:30 Supination, and its relationship between running, jumping and power in propulsion
36:00 Why joint motion should be the root of our efforts in injury prevention, rather than simply treating the tissue through strength-based exercises
45:30 Major biomechanical issues that show up with those athletes who have knee pain
50:00 The importance of stiffness, when called upon, in preventing knee pain
54:30 Using isometrics to assist co-contractions to help improve knee function
1:04.30 Thoughts on a joint based approach to knee pain
“I would be much happier with you having a flat foot that can experience some pronation and supination, versus a person with a neutral foot who can experience neither”
“People saying that “pronation is bad” is like saying “you shouldn’t bend your spine to the left”
“A collapse and a pronation are two different things”
“I don’t sell posture as a way to fix pain, I only relate to posture as a way to access movement”
“(In regards to tendon pain) If we are always going to presume that the tendon is the problem, then we are always going to assume that strength is the answer… but the problem is not always the tendon”

211: Cory Schlesinger Q&A on Autonomy-Driven Sports Performance, Isometric Training, and the Sport-Skill Continuum | Sponsored by SimpliFaster
Today’s episode features Phoenix Suns' head strength coach, Cory Schlesinger (and myself) answering questions on athletic performance training sent in from listeners. Topics for this show ranged from programming based on athlete-autonomy, to isometrics, to foot training, as well as important questions on blending strength work into a level of high-performance play where sport skill development far super-cedes one’s physical strength development.
Cory previously appeared on this show for episode #138 and is a popular speaker and podcast guest. Cory’s creative, yet practical style is an “athlete-first” method that gets results and leaves athletes with not only a first-class physical training experience but also facilitates their ownership in the process.

22:40 What the “Sun Café” is, and how it deals with the power of autonomy
34:05 Cory’s favorite isometric exercises for athletes
44:10 Achilles tendon injury prevention and gait biomechanics
51:50 Using floating heel work to improve the connection from the foot to the hip
0:58 Progressing an athlete’s strength development in tandem with their skill development
“You genetically gifted athletes who don’t need a lot of bar(bell) work, to be honest”
“Certain people need experiences that are a new experience, or experiences that give them a lot of confidence”
“Your grinders… what makes them confident? Squatting heavy weight, and you have got to give them that, but how do I expose them to things they are not good at to make their human capacities better?”
“You leave breadcrumbs to where you think the athlete needs to go”
“When I saw squat numbers go up, when I saw force place numbers go up… I did not see wins go up!”
“I don’t care what squat pattern a kid does, I really don’t”
“At Stanford, there was an environment where they got to pick the squat pattern, the extension pattern, whatever the meat and potatoes was that day”
“There is nothing more intentful, than them getting to choose what they want to do… having that autonomy is going to drive more results than them getting to predict their own success”
“Just because they do a between-the-legs dunk doesn’t make them a good athlete, that’s just one aspect of athleticism”
“The biggest low hanging fruit to get work done for me, is isometrics”
“My favorite (isometric) is a yielding isometric at the sporting angles that they create the most often”
“One of my favorite movements to load up is safety bar split, with a Hatfield hold (with a floating heel)”
“The one thing I do the most when identifying energy leaks, is super-heavy prowler pushes”
“In isometrics, if you put them in a position for long enough, you are going to see where their energy leaks are”
“The prowler was the original “floating heel squat”, if you do it right (without letting the heels mash down)”
“That’s how most Achilles tears happen (in basketball), is that false step, right into that forward (drive)”

209: Rocky Snyder on The Gait Cycle, Single Leg Work, and True Functional Training for Elite Athleticism | Sponsored by SimpliFaster
Today’s episode features personal trainer and human movement expert, Rocky Snyder. Rocky is the owner of Rocky’s Fitness in Santa Cruz, California, and is an experienced personal trainer, as well as an accomplished surfer and snowboarder. Rocky has taken an absolutely immense amount of continuing education in human performance and is the author of four books. His most recent being “Return to Center” , which featured a unique integration of a joint-based model of training and movement coaching, combined with neurological assessment of effectiveness.
“Return to Center” is the first training book in a very long time (outside of “Even with Your Shoes On” by Helen Hall that I read earlier this year), that I absolutely devoured (both books has heavy inspiration from Gary Ward, who has been a 2 time guest on this podcast, and developed the “Flow-Motion” model of tri-planar joint based analysis of human movement).
When it comes to “functional training” we often think of things like working on balance boards, or perhaps in a more realistic world, things like single-leg training and lots of bodyweight gait-pattern style movements, like crawling and heavy carries. Even in using these movements which are inherently more tied to human gait, they are often still performed under “manufactured” paradigms that take them outside of the scope of natural human movement and elasticity. Rocky has an incredible command of human movement principles, and can describe how these principles are showing up (or not!) in any exercise done in the gym, which is really the core of what we might call functional training.
For today’s podcast, Rocky tackles questions regarding his own joint-centered approach to training, as well as specifically how he looks at lunges and single-leg training in relation to the gait cycle, and how doing this optimally will improve joint health, VMO, and glute development, as well as athletic performance markers and injury reduction. This was a show that is a real key-stone in being able to truly train athletes on an individual level.

Quotes
“When getting the body to move as joints are expected to move, amazing things can happen”
“If we bring the body back into a more centrated place, the brain is going to allow a greater deal of force production”
“If you’re not going to explore how the (frontal and transverse planes) move then it’s going to reduce your ability to produce force in the sagittal plane”
“By knowing how the joints move in any exercise, it can tell the coach exactly what you are missing… the bottom line is that you should know how the body moves”
“The knee, when it pronates, should be flexing and externally rotating… the knee joint itself is rotating towards the midline faster than the tibia… am I seeing that when someone is lunging, or are they keeping it over the second toe because they have been told that it shouldn’t drive inward”
“A lunge is just an exaggeration of a walk, a gait pattern, that’s what a lunge should be”
“(In a lunge) Is the pelvis rotating away from the back leg and towards the front leg”

208: Christian Thibaudeau on Adrenaline, Muscle Tone and Optimizing Training Splits in Athletic Performance | Sponsored by SimpliFaster
Today’s episode features strength coach Christian Thibaudeau. Christian has been involved in the business of training for the last 18 years, having worked with athletes from 28 different sports. He is a prolific writer and presenter, having written four books, as well as presenting to top coaches and organizations all over the world.
Christian is also the creator of the Neuro-typing system, which classifies athletes according to the neurotransmitters they seek out. This system has the categories of 1A,1B,2A,2B and 3, and Christian has covered this topic extensively on this podcast, as well as many other shows.
There are many intersections of the neuro-typing system, as well as other categories of individualization. As discussed on my recent talk with Ross Jeffs, the “concentric”, “elastic” and “metabolic” sprinter types tend to fit with the 1A,1B and 2A neuro-types in regards to their strengths and optimal training regimen.
One element of training that I’ve been considering a lot is optimal training splits for sprinting and jumping athletes, and reconciling 4-day training splits (or even 6-day) where there is an intensive CNS element, versus more of a “high-low” split that Charlie Francis made so popular.
This new podcast with Christian digs into understanding how to give athletes their best training split by understanding the relationship of adrenaline to overtraining. It also looks at things like muscle tone as how one can make a better assessment of an athlete, what training they may respond best to, as well as how to assess them on a daily and weekly basis, and make the best training adjustments. Christian covers this, nutrition, child development and creativity, and much more on this information-packed show.

Quotes
“Any type of blue light or screen time is the number one enemy to child development”
“You will always have what I call grinders… they will never become the stars, and the stars are those that have that little extra something, and that comes from creativity”
“That’s one trait of high acetylcholine individuals, they will be more creative”
“Some people will break down adrenaline super-fast, and if they can do that, they can tolerate a lot more training stimulus. That is why some people naturally can tolerate a boatload of volume”
“COMT is the enzyme that breaks down adrenaline. The one that is fast will break down adrenaline very quickly after release, on the other hand if I have someone with a slow variation of the COMT enzyme, when you release adrenaline it stays high forever”
“The type 3 is very similar to the type 1a from a genetic perspective. Both have poor methylation, both have slow COMT, they don’t clear out adrenaline fast”
“Carbohydrates control adrenaline”
“The 1B is only aggressive under high adrenaline… they will be super chill until it counts”
“The 1B if he fails he will just try again. The 2A, looking foolish is destructive, because what others think of him is super important”
“Anxiety is nothing more than your brain firing too fast for you to control it”
“That person (who has high muscle tone) always has high adrenaline. To me that person has slow COMT, he doesn’t break down adrenaline fast”
“9 times out of 10 what we call overtraining is a desensitization of the beta-adrenergic receptors”

207: Edward Yu on Slowing Down to Run Faster and Integrating Sensory Awareness into Technical Acquisition | Sponsored by SimpliFaster
Today’s episode features Feldenkrais practitioner and human movement specialist, Edward Yu. Edward is a former triathlete, current martial arts enthusiast, and perennial student of Masters Li Xueyi and Ge Guoliang in the art of Bagua. Edward has worked with members of the US Olympic Track Team as well as those in the Portuguese National Ballet. Edward is also the author of “Slowing Down to Run Faster” the impetus of which came years after Edward quit running and discovered that conventional approaches to training are not always effective in turning people into better athletes. Edward’s interest in how people learn and process information has led him to mix the disparate fields of sports, martial arts, dance, psychology, cognitive science, information theory, and political economy into both his teaching and writing.
Learning about human movement and the acquisition of technique in sport skill has been an incredible, yet humbling journey for me. After hearing cue after cue from coaches that never worked, I was always looking into how we actually process and acquire skills as human beings. Two areas that I’ve dipped my toe into that I feel are vastly under-appreciated in sports performance are the martial arts, and then the world of movement through sensory awareness (such as the Feldenkrais method).
Today’s podcast is all about exploring human movement and sport technique from a wider lens. On the show, Edward and I cover many aspects that are particularly human when working on sport skills, such as over-trying, self-sabotage and motivational factors. Edwards also gets into his ideas on our sensory and motor development has humans, how our skills as adults hinge on things we need to learn as children, and how understanding that can lead us into new territory when it comes to guiding athletes to their optimal technique.

“We have a culture that’s really heavy handed with using will power and discipline and pushing to try and get results”
“I think if we look at the individual without looking at culture, and political economy, we are missing a lot. You have to look at both together”
“The self-sabotage in our culture has a lot to do with habits. If you just removed (the chair (from our culture) you gain a lot of advantages”
“If something is not learned in childhood, it is going to affect all more advanced/directed movement in the future. If we don’t go back and try to learn those fundaments, they will not be as efficient as they could be in the future”
“The potential for learning is not as vast (in animals versus for humans)”
“To learn to fun faster, you need to know what it means to learn”
“The way we are often coached is to try to imitate the ideal, but you can’t imitate what you don’t know in your own body”
“The fundaments for learning appear from the time we exit the womb, to the time we are 6,7,8, and a lot of that happens on the ground. It is very powerful to go on the ground,

206: Ross Jeffs on Individualizing Speed Training by Understanding Concentric, Elastic and Metabolic Sprint Types | Sponsored by SimpliFaster
Today’s episode features track and sports performance coach, Ross Jeffs. Ross is a sprints, jumps and hurdles coach at the Aspire Academy in Doha, Qatar. He formerly worked in the Netherlands as a sprints and jumps coach at Atletiek Trainingscentrum Rotterdam, and has also coached under the guidance of Jonas Dodoo within the Speedworks system. Ross has also worked with a number of athletes from a range of sports including a grand slam tennis player, professional boxers, Olympic medallists from basketball and rugby sevens, and World Cup finalists in rugby. Ross appeared on the podcast recently in episode 145.
In the training of athletes, be it in track and field or team sports, not all athletes respond to the same stimulus in the same way. Give 20 random athletes a diet of fast sprinting and heavy weightlifting, and some will respond amazingly well to it, others average, and some poorly. The same thing could be said of a plyometric focused program, as well as other types of setups. I first remember this idea of individualization in reading how the late Charlie Francis had mentioned some athletes liking heavy lifting, others plyometrics and bounding, while others responded well to the use of tempo training. Since then, I’ve been able to dig into things like Christian Thibaudeau’s neurotyping system, as well as Ross Jeff’s “trainers vs. racers” ideas on designing programs for athletes based on how far or close they can get to their competitive best in a practice environment.
Ross Jeffs is one of my favorite coaches and thinkers when it comes to training setups and organization to get the most out of athletes. He is continually asking questions and getting outside the box in order to help coaches and athletes understand training, adaptation and peaking better. Our conversation focus today is on sprinting, and how the differences of “concentric oriented”, “elastic oriented” or “metabolic oriented” are going to impact how these athletes are best trained and coached. This episode is also incredibly valuable for team sport coaches, where there is guaranteed to be more diversity than in a single track and field event in the process of coaching.
