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.

Cody’s early heavy-loading bias led to a total hip replacement and changed his training philosophy toward stability and movement quality. Reassess program priorities after a major injury: shift emphasis from maximal compressive loading to single-leg work, mobility, and stability. Use your injury story as a guardrail: design training that preserves life-long movement and allows play with family. Teach athletes the why: heavy strength is useful, but it must be paired with tissue resilience and mobility to avoid long-term breakdown. 5:31 – Coaching development, biases, and error-driven learning. Cody stresses that coaching wisdom grows from coaching people, making mistakes, and combining mentorship with hands-on experience. Get "skin in the game": coach real athletes and collect mistakes that refine your practice, not just textbook theory. Seek mentorship and internships to accelerate learning while still accepting the value of self-discovery. Avoid premature certainty: test provocative ideas and be ready to change your mind when evidence or outcomes demand it. 19:29 – The snapdown debate: context, progressions, and purpose. Snapdowns can be either a motor-learning tool for hinge/positioning or a low-value, non-stimulating ritual depending on context. Use snapdowns as a micro-dose progression: for young athletes, combine unweighting, pelvic control, and velocity to teach hinge and pretension. Do not use snapdowns as a one-size-fits-all landing mechanic; i...

James de Lacey, a professional strength and conditioning coach and founder of Sweet Science of Fighting, delves into the nuances of athletic strength and performance. He emphasizes the importance of rhythm and reaction in training for combat sports, linking Olympic lifting to real sport actions. Topics like oscillatory work and flywheel training show how movement quality can enhance athletic performance. James also discusses the effective mass in striking, relating these concepts to speed and power training, and practical drills that keep athletes game-ready.

Manuel Buitrago, PhD and founder of MaStrength, dives into the intricate world of Olympic lifting and muscle dynamics.

Today’s guest is Romain Tourillon. Romain is a sports physiotherapist and researcher specializing in the foot–ankle complex, with clinical leadership at the Swiss Olympic Medical Center, La Tour Hospital (Geneva). His PhD at Université Jean Monnet Saint-Étienne examined foot muscle strength and sport performance. It’s important to train the lower legs in athletes, but the question is what type of training is best, especially when it comes to working the toes and forefoot, versus more general calf and shin work. In this episode, Romain discusses his research on forefoot biomechanics and performance. He shares training that boosted MTP (big-toe) flexion strength ~28% in trained athletes and explains how stronger forefeet enhance sprinting, cutting, and jumping via better force transmission and stability. We also cover injury prevention, targeted foot/ankle exercises, challenges in measuring toe strength, and where 3D analyses may take the field— with practical takeaways for coaches and athletes throughout.

Test new foot or ankle drills on yourself first to refine cues and feel. Note the sensations and difficulties athletes might face before implementing. Use self-testing to build better communication and progression strategies. 4:46 – Using Everyday Objects to Innovate Foot Training The “foot bridge” concept came from standing barefoot on two bricks, showing that creative setups can unlock new sensations without expensive tools. Incorporate simple props like bricks or angled boards to change foot loading. Create small balance challenges to engage the toes and arches differently. Use low-cost, adaptable tools to spark innovation in foot training. 8:16 – Surface Texture and Proprioception in Barefoot Work Different surfaces alter how foot muscles activate, making proprioception a key training variable. Rotate athletes between rough, smooth, and dampened surfaces to shift activation. Use barefoot drills regularly to strengthen sensory feedback from the toes. Treat surface texture as a deliberate tool to adjust difficulty and stimulus. 11:27 – Breaking Down Romain’s PhD Research on the Forefoot Romain studied how forefoot strength training impacts sprinting, cutting, and jumping performance. Add structured toe flexion and forefoot drills to comple...
