Lifting more weight doesn't always mean you've gotten stronger. In this foundational session, Dr. Jordan Feigenbaum and Dr. Austin Baraki introduce the Fitness-Fatigue Model to explain why "stalled" progress is often just a temporary masking of strength by accumulated fatigue. By learning to differentiate between a lack of fitness adaptation and a lack of recovery, you can avoid the "panic pivot" and maintain the long-term signal necessary for elite-level gains.Supercast Sign-UpFor the 6-part audio series and Training Plateau Action Plan, sign-up for Barbell Medicine Plus:https://barbellmedicine.supercast.com/Key Learning PointsThe Fitness-Fatigue Model: Understand the physiological duality of every workout—while a session builds your "fitness" (potential), it also creates "fatigue" that temporarily suppresses your performance.Strength vs. Effort: Performance must be measured relative to RPE. If the weight on the bar increases but the RPE climbs disproportionately (e.g., jumping from RPE 8 to RPE 10 for a 5lb gain), your absolute strength has not actually improved.Noise vs. Signal: A one-week stall is statistical "noise." Constant program hopping in response to a single bad session destroys the cumulative stimulus (the "signal") required for actual tissue adaptation.The Root Cause Audit: Determining the "Why" behind a plateau.Lack of Fitness: The stimulus is no longer sufficient to drive a new adaptation (Needs more volume/intensity).Lack of Recovery: The fatigue is overwhelming the adaptation (Needs a deload or volume reduction).Autoregulation as a Diagnostic Tool: Using RPE not just to prescribe load, but to "interrogate" your current state of recovery and readiness.Timestamps[00:00] Intro: Introducing the Barbell Medicine Plus Exclusive Series[02:15] The Thought Experiment: 310x6 @ 8 vs. 315x6 @ 10[05:30] Deep Dive: Defining the Fitness-Fatigue Model[09:45] Interpreting the Stall: Is it a Stimulus Problem or a Recovery Problem?[14:20] The Danger of "Short-Termism": Why Panicking Destroys the Signal[18:50] Introduction to the 6-Part Audio Course & Actionable PDFPearlsThe Pivot Rule: Never change a successful program based on a single week of data. Look for a 3-week trend of stagnant or declining performance (at the same RPE) before initiating a program pivot.Peaking Mechanics: Most "peaking" protocols do not build new strength; they simply reduce fatigue to reveal the strength you've already built.The stimulus-Recovery Trap: If you feel "beat up" but the weights are moving well, you likely don't need a deload yet. If you feel "great" but the weights are stuck, you likely need a stronger stimulus.Our Sponsors:* Check out FIGS and use my code FIGSRX for a great deal: https://wearfigs.com* Check out Factor: https://factormeals.com/bbm50off* Check out Quince: https://quince.com/BBM* Check out Quince: https://quince.com/BBMSupport this podcast at — https://redcircle.com/barbell-medicine-podcast/donationsAdvertising Inquiries: https://redcircle.com/brandsPrivacy & Opt-Out: https://redcircle.com/privacy
