Today’s guest is Bill Smart. Bill is a sport scientist and physical preparation coach specializing in elite fight-sports performance. As the founder of Smarter Performance and the Strength & Conditioning lead for the CORE MMA team, Bill integrates cutting-edge evidence with real-world high-performance systems to enable combat athletes to show up on fight day in optimal physiological condition.

Much of the conversation in sports performance hinges on speed and power development, or conditioning, as a stand-alone conversation. Sport itself is dynamic and combines elements of speed, strength, and endurance in a dynamic space. Training should follow the same considerations to be truly alive and effective.

In the episode, Bill shares his journey from cycling and rowing to combat sports. He discusses how long isometric holds develop both physical and mental resilience, and their implementation in his programming. The conversation dives into muscle-oxygen dynamics, integrating ISOs with conditioning, and how testing shapes his approach. Bill also explores flywheel eccentrics, fascicle-length development, and why sprinting is a key element for maintaining elastic power in elite fighters.

Today’s guest is Sam Elsner. Sam is a former NCAA Division III national champion thrower turned motor learning writer and educator. He’s the author of The Play Advantage and creator of the Substack CALIBRATE, where he explores how humans learn movement through play, perception, and environment design. Sam brings a rare blend of elite athletic experience and deep skill-acquisition insight to help coaches and athletes move beyond drills toward true adaptability and creativity in sport.

As athletic performance is largely driven by weight-lifting. It digs in to maximal strength and force-related outcomes in such excess that all other elements of athleticism are negated. Skill learning and high velocity movement are the wellspring of sporting success. As such, having a balanced understanding of the training equation is critical for the long-term interest of the athlete.

On today’s podcast, Sam and I dive into how athletes truly learn to move. Sam traces his journey from WIAC throws circles to Cal Dietz’s weight room, why a rigid “triphasic for everyone” phase backfired with a soccer team, and how ecological dynamics and a constraints-led lens reshaped his coaching. Together we unpack the strength–skill interplay, 1×20 “slow-cook” gains versus block periodization, the value of autonomous, creative training application. We touch on youth development, culture, and team ecology, plus where pros are experimenting with these ideas. This episode is loaded with both philosophy of training and skill learning, along with practical takeaways in program design.

Today’s guest is Ben Simons. Ben is a British performance coach and two-time Olympic bobsledder with a background in sprinting and sports science. A former World Cup gold medallist, he’s now focused on helping athletes develop speed, power, and coordination through evidence-based, real-world training methods. Ben blends biomechanics, motor learning, and nervous-system training to build explosive, adaptable athletes.

Many speed training topics and conversations focus exclusively on the most stimulating possible methods; fewer get into individual factors, athlete adaptability, and how that speed and power training evolves with the needs of the athlete.

On today’s show, Ben and I discuss asymmetry, rhythm, and “aliveness” in sprint and power development. We explore when to let unique mechanics—like Byanda Wlaza’s galloping stride—run their course versus coaching toward a technical model. Ben gets into the general speed training lessons he gained from bobsled, and shares why he now favors yielding isometrics, unilateral strength, and med ball throws over heavy lifts, emphasizing longevity, reflexive strength, and movement variability. We finish with how curvilinear sprints, pool work, and playful, multi-directional movement help athletes stay reactive, adaptable, and pain-free.

Today’s guest is Cody Hughes. Cody is a strength and performance coach at Farm & Forge in Nashville, blending over a decade of collegiate and private-sector experience into a practical, athlete-centered approach. His work bridges foundational movement with modern tools like VBT and GPS tracking, always anchored by the belief that health drives performance.

With the rising influence of technology in training, it can become more difficult to look clearly at the core facets of athletic force production, as well as how to optimally use technology to fill gaps, inform decisions, and even motivate groups.

On today’s episode, Cody traces his shift from heavy-loading bias to a performance lens built on force management, eccentric RFD, and training that actually reflects sport. We unpack depth drops vs. “snapdowns,” why rigid “landing mechanics” miss the mark, and how movement literacy, variability, and velocity drive speed and durability. On the tech side, we get into velocity-based training (VBT) as a feedback and motivation tool, using it to gamify effort and auto-regulate load, and knowing when to remove the numbers to protect recovery and intent.

Leaderboards, incentives, and smart stimulus design all matter, but Cody keeps it clear that data supports the human element that produces real power.

Today’s guest is James de Lacey. James is a professional strength and conditioning coach and the founder of Sweet Science of Fighting, a leading platform for combat sports performance. He has coached in professional rugby leagues across New Zealand, Europe, and the United States, and has trained athletes in MMA, boxing, Muay Thai, and BJJ. Through Sweet Science of Fighting, he delivers evidence-based programs and education for fighters and coaches worldwide.

Strength training for athleticism typically focuses on sets, reps, and general forces, but rarely gets into aliveness and skill management of the resistance itself. The former is great for building basic physical competencies, but in integrating the latter, we can breathe more life into a performance program.

On today’s show, we dive into James' approach to building athletic strength and power across multiple mediums. We explore how Olympic lifting, especially pull variations, connects to real sport actions, and how striking and collision sports highlight the importance of timing, rigidity, and effective mass. We also break down resistance methods like oscillatory work, flywheels, and accentuated eccentrics, focusing on their alive, reactive qualities rather than just load. These principles carry into speed and power training, including plyometrics and sprinting, with rhythm and movement quality as a central theme. The episode makes strong connections between field sports and combat sports, showing how momentum, relaxation, and rigidity at impact shape performance.

Today’s guest is Manuel Buitrago. Manuel is a PhD, along with being the founder and director of MaStrength, a global education brand dedicated to authentic Chinese weightlifting. Since launching MaStrength in 2014, he’s taught 100+ seminars worldwide, authored Chinese Weightlifting: A Visual Guide to Technique and Chinese Weightlifting: Technical Mastery & Training

There are many misconceptions in the world of strength training, especially as the lens of a skeletal pressure-based view is not included in modern training systems. When skeletal pressure dynamics are understood, it allows us to see why athletes prefer particular variations of lifts, how and why they fail lifts, and what aspects of the lifts themselves lead to better athletic outcomes.

On today’s episode, Manuel speaks on the practicalities of weightlifting and how it carries over to sport. He compares powerlifting and Olympic lifting from a technique and transfer standpoint, and gets into how body shapes, breathing, and set-ups affect a lift. Manuel also touches on connective tissue and why it matters for performance and durability. From this episode, you’ll learn concepts about the Olympic and powerlifts that can not only improve lifting performance but also facilitate a better transfer to athleticism and movement ability.

Today’s guest is Kathy Sierra. Kathy Sierra is a computer scientist, author, and horse-movement innovator who bridges neuroscience, learning psychology, and equine training. Co-creator of the award-winning Head First programming series and founder of the JavaRanch community, she later turned her expertise in intrinsic motivation toward her lifelong passion for horses. Through her Panther Flow approach, Kathy helps horses and riders unlock confident, curious, and expressive movement, sharing her work worldwide through courses, workshops, and writing.

In training and movement, drilling “perfect form” is standard practice. The more we get into how humans learn, the more we realize that “perfect form” is a myth, and learning is a far more complex venture. Using both differential learning (variety) and constraints helps athletes hone in on their own optimal (and robust) technique, without needing to constantly be looking for one “perfect” way to do things.

This is not only true in animals, but also in humans and in machine learning. On this week’s episode, Kathy covers aspects of training horses using the same motor learning concepts that work best in humans. She also goes into how and why robots learn to move better based on constraints, trial and error, versus a “perfect technique” type of programming. This is a fascinating and wide-ranging discussion on human movement, learning, and sport skill.

Today’s guest is Michael Zweifel. Michael is the Defensive Coordinator and Defensive Backs Coach at UW–La Crosse, now in his fourth season with the program. He previously founded Building Better Athletes (BBA Performance) in Dubuque, Iowa, training athletes from youth to pro levels. Michael also coached at Clarke College and the University of Dubuque. A former record-setting wide receiver, he won the 2011 Gagliardi Trophy and still holds the NCAA all-divisions career receptions record (463).

In athletic development, the “5 S’s of performance”: Strength, Speed, Stamina, Suppleness and Skill” are often brought up. What tends to be the case is those 5 elements are weighted in that order, with skill mentioned, but rarely or ever studied in how to improve it.

On today’s show, Michael discusses his own creative approach to skill development in American football players with an emphasis on building artistry and adaptability in his players. He speaks on the nature of constraint-based coaching that helps athletes improve their arsenal of movements on the field, as well as their decision making skills in the midst of chaos. We also touch on the crossover between basketball and football, and ultimately the art of long-term development of skill in one’s sport and as an athlete in general.

Today’s guest is Will “Hoss” Ratelle — former All-Big Sky linebacker turned strength and conditioning coach, with experience at the University of North Dakota, the NFL, and the CFL. Known for his intense, results-driven training style, Hoss blends his pro football background with evidence-based methods to build size, speed, and resilience in athletes. He’s also the creator of popular programs like “Hoss Concurrent” and a respected voice in the online performance space.

Most fitness and training education tends to be rigid, centered around fixed sets, reps, heart rate zones, and prescribed loads and timing. While this structure has value, athletes eventually need to move beyond it and enter a more adaptive, natural rhythm of training. Sets and reps can serve as a starting point, but great coaching gives training a feel, one that fosters ownership, problem-solving, and deeper athlete engagement.

On today’s episode, Will Ratelle shares practical strategies for building training protocols that allow for flexibility and athlete autonomy. He discusses how to keep athletes dialed in during strength and power work, while also diving into topics like hamstring rehab, velocity-based training, and more.
