Consult workflow for stalled lifters

Three weeks of stalled squats. The conventional answer is to switch programs because you've crossed into intermediate territory. The data says something else. In Part 3 of the Progressive Loading series, Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through why the standard novice / intermediate / advanced framework runs into trouble in real training, what the four adaptive systems are actually doing across a training career, and why most of what gets called a stall is impatience with the noise floor at your current strength level.

This is Part 3 of the Progressive Loading series. Part 1 covered why loading should react to demonstrated adaptation. Part 2 covered RPE-based autoregulation and the artificial-momentum approach. Today is the mechanism layer.

What we cover 

- The novice / intermediate / advanced framework: three claims and why each one fails the data test

- The 17-year IPF strength curve and what the no-kink finding does and does not establish (Latella 2024)

- The four adaptive systems and their separate timescales (neural, muscle, connective tissue, bone)

- What early growth actually is, including the deuterium-oxide finding that most week-3 size is fluid (Damas 2016)

- Why connective tissue lags muscle by six to eight weeks, and why that produces patellar tendinopathy four months in

- The 9.5 vs 0.74 to 3.3 injury rate gap between novice and experienced CrossFit participants

- The CNS fatigue myth and the Skarabot 2018 finding that locates the fatigue in the muscle, not the brain

- Why the LIFTMOR trial result (heavy lifting for bone density in women in their 60s and 70s) is being missed by primary care

- A practical decision tree for stalls: environment first, then load, then program

- Tease for next week: leptin, the HPG axis, and the metabolic driver of low testosterone almost nobody connects
