Foot position changes the strategy. 👉 Start learning FREE at https://www.uhp.network 💡 Foot position is often treated as preference or style. In reality, it is a constraint that reshapes how the system manages rotation, pressure, and force. In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus examine ramps, heel elevation, flat foot positions, and toe-only loading. They explain how each option biases propulsion, what each choice gives you, and what it quietly takes away when used without intention. This is not about labeling movements as good or bad. It...

Should You Get Certified? How to Choose the Right Education for You 👉 Start learning FREE at https://www.uhp.network 💡 Not all certifications are created equal. And more letters after your name won’t guarantee better outcomes. In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus discuss what it really means to become a skilled practitioner — and why many educational paths lead to confusion instead of clarity. This episode introduces the new UHPC Practitioner Certification Pathway, but it’s more than an announcement. It’s a guide to rethinking your...

Balanced training isn’t about push vs pull. It’s about pressure, shape, and strategy. 👉 Start learning FREE at https://www.uhp.network 💡 Most training imbalances aren’t muscle problems. They’re compressive strategies that limit movement options. In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus challenge the traditional idea of “balanced training” and explain why pushing and pulling are not opposites at all. They explore how all loaded exercise increases compression, how force production shapes the body, and why chasing symmetry in the gym often creates...

Shoulder pain isn't a mystery. It's a strategy. 👉 Start learning FREE at https://www.uhp.network 💡 Shoulder impingement isn't caused by a faulty shoulder. It's a shape problem. In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus break down the three common types of shoulder impingement (and one bonus type). They focus on constraint, space access, and thorax behavior instead of outdated diagnoses. You’ll learn: 🔸 Why impingement isn't about the rotator cuff, and what to look at instead 🔸 How thorax compression creates the illusion of local...

The ISA isn’t the answer. It’s the question. 👉 Start learning FREE at https://www.uhp.network 💡 Most people measuring ISAs are looking for a fixed answer. But in the UHPC Model, the infrasternal angle (ISA) isn’t a number — it’s a behavior. And if you’re basing your entire intervention strategy off “wide vs narrow,” you’re likely missing the point. In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus break down what the ISA really tells you (and what it doesn’t). It’s one of the most searched topics on our YouTube page — and also one of...

Stretching ≠ solving hamstring tightness. 👉 Start learning FREE at https://www.uhp.network 💡 Feeling “tight hamstrings” doesn’t mean your hamstrings are short and need to be stretched. It means your system is expressing a strategy under load. In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus walk through why stretching often makes hamstring tightness worse — and what actually drives lasting change. You’ll learn: 🔸 Why hamstring “tightness” is usually a protective output, not a length problem. 🔸 How anterior...

Stop guessing with assessments. Start learning from the source. Free courses and the new Assessment 101 are waiting for you: http://UHP.network Think you know how to assess a squat? Think again. In this episode, Bill Hartman and Chris dismantle the myth of “squat as pattern” and show you how to actually use squats as diagnostic behavior. The focus is on propulsion, internal rotation, and how the system expresses its real strategy. You’ll never look at a butt wink, heel lift, or shift the same way again. What You’ll Learn Why squats are not universal patterns. They are...

It is so much more than biomechanics… → Join http://UHP.network FREE to start learning. Not a pattern. Not a form. A strategy. This episode redefines everything you thought you knew about squatting — through the lens of the Unified Health & Performance Continuum (UHPC) Model. We dive deep into the energetics of squatting, shape acquisition, center of gravity descent, and why movement patterns are a misleading lens. You’ll learn how strategic resistance influences squat mechanics, why some people “butt wink,” and how propulsion phases explain squatting better than any...

"You’re Not Measuring What You Think: Movement Screens, Compensations, and Energetic Behavior" → Join http://UHP.network FREE to start learning. Episode Overview Bill and Chris explore how complex movements—like squats, toe touches, and turns—serve as energetic assessments within the UHPC Model. Rather than relying on outdated biomechanical frameworks or traditional mobility screens, they explain how movement reflects behavioral strategy under constraint. Gravity, pressure, and shape—not joints or range of motion—govern what you see. The episode walks through real examples,...

Episode Overview Bill and Chris unpack the philosophy and implementation of assessment within the UHPC Model, showing how testing reveals energetic behavior—not just structural position. Rather than focusing on static joint angles, they illustrate how relative motion, systemic organization, and phase-based strategies tell the real story of what a system can or cannot do. The discussion critiques isolative and reductionist interpretations and offers a coherent, propulsion-informed approach to understanding and intervening effectively.

💡 Most people measuring ISAs are looking for a fixed answer. But in the UHPC Model, the infrasternal angle (ISA) isn’t a number — it’s a behavior. And if you’re basing your entire intervention strategy off “wide vs narrow,” you’re likely missing the point.
In this episode of the UHPC Podcast, Bill Hartman and Chris Wicus break down what the ISA really tells you (and what it doesn’t). It’s one of the most searched topics on our YouTube page — and also one of the most misunderstood.
You’ll learn:
🔸 Why the ISA is a proxy measure.
🔸 The most common errors people make when assessing rib cage shape.
🔸 How compression, compensatory strategy, and behavior blur structural bias.
🔸 When your “narrow” isn’t really narrow — and how to know.
🔸 Why trusting the process matters more than getting the angle right.
⚠️ If you’ve ever had someone tell you you’re “wide” — only to later learn you’re “actually narrow” — this episode explains why that happens, and how to interpret ISA inside the full system.
🧠 The ISA doesn’t predict outcomes. The response to intervention does. Learn how to measure, sense, and course-correct inside the only coherent movement model that connects structure, behavior, and constraint.

0:00 — Why the ISA conversation keeps coming back
Chris and Bill discuss how the YouTube algorithm loves ISA content — but it often draws people in through the wrong lens. They talk about why the ISA is misunderstood and why it's not a stand-alone model.
1:50 — What the ISA actually is
Not a number. Not a diagnosis. It’s a proxy for rib cage behavior during breathing — and it requires context, structure, and experience to interpret properly.
4:36 — Experience matters more than accuracy
Why you need more reps to understand ISA. The difference between making a wrong call and letting the response reveal your answer.
10:52 — What not to do when measuring ISA
Bill explains why using a goniometer, fixating on symmetry, or basing your entire intervention off of ISA alone will lead you down the wrong path.
13:44 — Archetypes, compensation, and behavior
They dig into how structure becomes more apparent after compensation is resolved — not at the beginning — and why this trips people up.
19:36 — Why behavior reveals more than structure
ISA “types” can look the same under compression. But when behavior is reorganized, structure becomes clear.
22:36 — Measurement is a beginning, not a conclusion
This wraps with how to let the system show you where to go — even if your initial measurement was off — by using process, response, and KPIs.
