The CNS Fatigue Myth @BarbellMedicine

Uploaded May 2026 | Updated September 2026, 2 weeks ago

CNS fatigue has real cultural traction in the lifting community. The claim that advanced lifters are uniquely limited by accumulated central nervous system fatigue, and therefore require categorically different programming, has been tested directly. The data does not support the standard story.

In this segment from the Barbell Medicine Podcast, Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through Skarabot 2018, which used direct electrical nerve stimulation and transcranial magnetic stimulation to localize where the fatigue from a hard squat session actually sits. Plus a 2024 Garcia-Ramos finding showing that lower-load sets to failure produce more acute fatigue than heavy low-rep work performed below failure.
If you are dropping heavy work because you think your nervous system needs a longer break, this segment is for you.

2:30 - What they found: peripheral, not central
3:15 - The high-rep set actually hits you harder (Garcia-Ramos 2024)

$Body Composition, Bone, Brain, & the Fitness Changes (Data vs the Influencers) I Menopause Part 3 Most women in 2026 are told menopause affects everything, the weight, the belly fat, the bones, the heart, the brain, and that the fix is hormones, supplements, and a proprietary protocol. The data tell a different story. Menopause does some of it, but not all of it. Dr. Jordan Feigenbaum and Dr. Austin Baraki — with OB-GYN Dr. Loraine Baraki at the clinical changes — put real numbers on what menopause actually does to body composition, cardiometabolic healh around the final menstrual period, bone, cognition, and sleep. Then the single biggest modifiable lever against what actually kills postmenopausal women — which isnt a hormone. This is Episode 3 of Barbell Medicines four-part menopause series.
