Sprint Mechanics & The CNS — Loading the Right System
Why "do more sprints" is the wrong answer for most athletes. A look at nervous-system sensitivity vs. plasticity and what it means for how you dose speed work.
Long-form podcast appearances, conference talks, and on-site clinics for pro teams, universities, and coaching federations.

Brazilian jiu-jitsu coach Ellee Beckman (Art of Coaching, Australia) on the coaching underneath the chaos — from a four-year-old "breathing fire" out of a closed guard to the deeper principles of teaching, constraint, and athlete development.
ListenA field report from the Emergence Movement Conference, where debates replace slides and coaches actually talk face to face. Jeff unpacks the real argument underneath ecological dynamics: capacity versus transfer, and what it means for how we coach.
ListenPosturologist Paul Gagné on why some athletes dominate in games while looking average in the weight room. How the brain uses vision, the vestibular system, and the foot to organize posture — and what that means for performance.
ListenParkour coach, builder, and founder of The Movement Creative on how movement can be a first language — turning a city into a classroom and frustration into the felt sense of learning.
ListenDr. Ty Melillo on how left-right brain asymmetry shows up in autism, ADHD, dyslexia, immune quirks, and gut issues — and how movement, sensory training, and targeted nutrition create real change.
ListenCoach Javi Miller Estrada (Ignite Performance, Emergence, Adaptable Athlete Podcast) on what it actually looks like to coach perception instead of technique — and why your athletes should get better at the game, not just better at drills.
ListenOlympic sprint and jumps coach Randy Huntington and Exogen's Joseph DeSetti unpack the methods, measurements, and micro-loads behind elite speed — from Chinese training systems to wearable resistance.
ListenOrthopedic surgeon and posturology pioneer Dr. Bernard Bricot on why posture isn't about "standing up straight" but about how the brain reads the world through the feet and eyes — and what that means for back pain, performance, and the body.
ListenA year-end solo episode unpacking the ideas that changed Jeff's training and his life — primitive reflexes, posturology, ecological dynamics, play, and why the fastest path to better performance is becoming more human first.
ListenAuthor and Feldenkrais practitioner Todd Hargrove connects three big ideas: how humans evolved to move, what childhood development teaches us about adult movement, and why "your squat is wrong" is the wrong question.
ListenMovement pioneer Rafe Kelley on how our disconnection from nature, play, and community shapes modern discomfort, anxiety, and performance — and what reconnecting actually looks like.
ListenShelby Copeland (Force of Nature) reframes fitness: solving movement problems instead of grinding reps. A conversation about what exercise can be when it stops imitating machines.
ListenChad Emmons, strength and conditioning coach for Haas Factory Team (NASCAR), on the unseen athletic world of a pit crew — and what race prep teaches about reaction, decision-making, and training under chaos.
ListenAnna Bezuglova (Bamboo Body, Barcelona) on 11 years of study under Ido Portal, and why movement practice is whole-person training — not just physical fitness.
ListenWater researcher Robert Gourlay (MEA water devices) on structured, negatively-charged water — and why it may be the fastest path to better cellular health and whole-body function.
ListenJohn Iams on moving past mechanical models of pain toward a model that actually matches what patients feel — and what that means for coaches working with injured athletes.
ListenA solo episode laying out Jeff's step-by-step framework for moving an athlete from post-rehab back to full performance — assessment, capacity, then exposure.
ListenGreg Souders on training athletes like wolves, not dogs — autonomy, environment, and coaching for adaptability over compliance.
ListenDr. Robert Melillo on primitive reflexes, brain hemispheric integration, and how neurological development underwrites everything an athlete can become.
ListenPodiatrist Andy Bryant on natural foot function — what healthy feet actually do, why most shoes work against them, and what that means from the ground up.
ListenMat Boulé returns to dig into the deep end of functional neurology — why the brain, not the muscle, is the bottleneck in athletic performance and rehab.
ListenA solo deep dive into Anatoli Bondarchuk's transfer-of-training system — what still holds up, what needs updating, and how it shapes Jeff's programming.
ListenTyler Yearby on softness, adaptability, and what martial artists and athletes can learn from water — yielding, redirecting, and finding strength in letting go.
ListenMeredith Ole on the biology of light — how photons, mitochondria, and circadian rhythms interact, and what "human optimization" looks like when you include the sun.
ListenKarin Bensabat on becoming a movement teacher — not just a coach. What it looks like to develop a practitioner's eye and to actually transmit feel, not just cues.
ListenFive core topics available for conferences, in-house clinics, federation events, and university coaching staffs.
Why "do more sprints" is the wrong answer for most athletes. A look at nervous-system sensitivity vs. plasticity and what it means for how you dose speed work.
Translating the constraints-led approach from theory into actual gym drills. Why training perception beats mechanical cueing for transfer.
A working framework for classifying exercises by their transfer potential, and how to sequence general → specialized work over the long arc of development.
A practical workshop on integrating neurological development (vision, vestibular, proprioception) with traditional strength and conditioning.
When the program isn't working: a 5-step checklist that starts with what to remove, not what to add.
Whether it’s a 30-minute podcast, a 90-minute keynote, or a full-day clinic for your coaching staff — Jeff brings the same approach he uses with athletes: assess first, then build the plan.
