Rethinking the warm-up: what Starrett, Galpin and Huberman recommend
Kelly Starrett warms up with play and breath holds, Andy Galpin covers warm-ups in his strength protocols, Huberman explains warming up and whether to stretch before or after training, and the B-Team grapplers describe their own warm-ups. A warm-up is the part of a session most people improvise, and these sources give it a purpose and a structure.
Speed, power or size: where strength fits for fighters and skill athletes
Max Holloway trains for speed, not size, Bert Sorin explains why power matters for fighters, Chris Duffin discusses strength in skill sports and the speed of relaxation, and Georges St-Pierre, John Danaher, Gordon Ryan and Israel Adesanya describe where strength work fits in their preparation. Athletes in skill sports have limited training time, so how much of it goes to strength is a real choice.
Win bonuses and fighter pay: what fighters say about combat sports money
Francis Ngannou, Dustin Poirier, Aljamain Sterling and Matt Serra's group talk through win bonuses or fighter pay, and Craig Jones built a tournament with more than $2 million in prize money around athlete pay. Their accounts show how the money in combat sports reaches the athletes, which fans rarely see.
Better gloves, fewer stand-ups, no cage: the MMA rule changes insiders want
Joe Rogan sets out his rule changes with Israel Adesanya, Jiří Procházka and Belal Muhammad (up kicks, referee stand-ups, better gloves, covered fingers, no cage), while Royce Gracie, Tank Abbott, Rico Verhoeven, John McCarthy, Justin Gaethje with Trevor Wittman, and Matt Serra's group debate gloves, eye pokes, kicks to the knee and rules that make no sense. Rules decide which techniques count and how fighters get hurt, so the changes the sport's own people keep asking for are worth setting side by side.
Zone 2 and breathless intervals: how experts build the cardio week
Huberman's fitness tools start from 150 to 200 minutes of zone 2 cardio a week and add harder sessions, Rhonda Patrick swaps 10,000 steps for 10 breathless minutes, Stacy Sims tells women to polarize their training and sprint briefly, and Vonda Wright's routine pairs walking with sprinting. Seeing how each of them combines easy and hard work helps a reader spend limited cardio time well.
Protocol overwhelm: why health experts keep returning to a few core habits
Rhonda Patrick says you do not need 50 health hacks, Rangan Chatterjee reduces health to four pillars, Mel Robbins boils expert advice down to breathing, walking and sleep, and Huberman answers a listener's question about protocol overwhelm by saying optimization should serve your life. Their shared answer to endless health information is a short list of basics, which gives an overloaded reader a place to start.
Fixing fight judging: why fighters and commentators say MMA scoring is broken
Fight Companion panels argue over the 10-point must system and disputed decisions, Rico Verhoeven lays out how he would fix judging after a controversial stoppage, and John McCarthy explains how judges actually see a fight. Bad scorecards change careers and pay, so the specific reforms these insiders propose matter to anyone who follows combat sports.
Overreaching or overtraining? The warning signs and how to track recovery
Andy Galpin lays out the stages from useful overload to true overtraining and the metrics that track it, Kyle Gillett warns of an overtraining trap that works against hormone health, Huberman lists recovery tests such as heart rate variability and carbon dioxide tolerance, and Peter Attia notes that extreme exercise has a cost. Knowing the difference lets people push hard without sliding into months of lost progress.
Stem cells for injuries: what fighters swear by and what doctors say
Rogan and his fight-world friends trade stories of stem cell clinics, and he and Terry Bradshaw disagree about them in a friendly way, while physician Craig Koniver describes how he uses them and Stanford neurosurgeon Gary Steinberg describes stem cells as a recovery tool after brain injury. Putting the testimonials beside the clinical accounts helps readers tell hope from evidence before paying for treatment.
Breathing for the gym: bracing during lifts and calming down afterward
Andy Galpin explains how to breathe during a lift and how to down-regulate after training, Huberman's fitness tools include breathing between sets and at the end of a workout, Galpin's recovery episode lists breathing among the fastest recovery tools, and Pavel Tsatsouline teaches breathing for power. Breath is the one recovery and performance lever available in every session at no cost.
Cancer risk you can change: screening, metabolism, alcohol and immune defenses
Jason Fung describes cancer as a seed that needs the right soil, Peter Attia and Chris Thompson argue for earlier and better screening, and immunologists explain why tumors slip past the body's defenses. Together they show which parts of cancer risk a person can act on and where the experts still disagree.
How much lifting builds muscle: weekly volume, effort and session length
Huberman's muscle episode covers how many sets, how long and how often, Andy Galpin offers a forgiving hypertrophy framework built on volume near failure and variety, and Jeff Cavaliere argues for sessions under an hour that are hard instead of long. Together they give a clear range for muscle growth, which is a different goal from maximal strength and is programmed differently.
Never too late: what starting to train after 50 delivers
Vonda Wright rejects the idea that decline is inevitable, Layne Norton and Pavel Tsatsouline explain how to lift safely later in life, and performers in their seventies describe getting stronger than they were at 50. Their accounts answer the common worry that the window for building strength has already closed.
Turning Back the Clock: Age Reversal, Escape Velocity and What Is Actually Proven
David Sinclair reports that a cellular reprogramming therapy has entered its first human trial, Ray Kurzweil forecasts more than a year of added life expectancy per year by the end of the decade, and Nick Bostrom and Michael Levin add what ending aging would demand and another biological route to it. The sources contain no outside critic of these claims, so this piece sorts each one by its evidence: shown in animals, shown in human cells, under test in people, or still a prediction.
Your mouth is a health organ: oral bacteria, fluoride and whole-body disease
Dentist Staci Whitman and Huberman's oral health episode treat the mouth as a living ecosystem that teeth repair within, and warn that harsh mouthwash and constant snacking damage it, while James Nestor ties shrinking jaws to breathing problems. Looking after the mouth turns out to protect far more than teeth.
Does cardio kill your gains? How to combine lifting and endurance
Andy Galpin explains the interference effect, Huberman's endurance episode covers concurrent training and recovery, Jeff Cavaliere says where to place conditioning in a week, and Huberman's hormone and daily-routine episodes add rules for which to do first and in what ratio. Most people want both strength and stamina, so knowing when the two actually interfere, and how to order them, saves wasted effort.
How much to drink when you train: the Galpin equation and salt
Andy Galpin gives a simple formula for fluid during exercise and warns that both too little and too much water hurt performance, and Huberman's salt, water and endurance episodes build on the same equation with sodium and electrolytes. It replaces vague advice to stay hydrated with numbers a person can use in a workout.
Fitness without a finish line: how performers in their fifties to seventies keep training
Adam Sandler, Tom Segura, Ron White, Rick Springfield, Bryan Callen and MrBallen each describe to Joe Rogan the routines that keep them strong as they age, and veteran fighters and a retired special operations soldier talk about staying on the mats in their fifties. None of them follows a program with an end date, and their accounts favor steady habits that survive injuries and touring over short bursts of intensity.
Erectile dysfunction as an early warning: blood flow, not hormones
Urologists Michael Eisenberg and Rena Malik say most erectile problems come from blood vessels and the pelvic floor and often appear before heart disease does, and Kelly Starrett and Kyle Gillett add the movement and lifestyle side. Men who treat it as a health signal get a chance to fix the cause early.
Growth hormone: the youth hormone that may not lengthen life
Clinics offer growth hormone and drugs that release it to restore youthful muscle and skin, and Kyle Gillett and Craig Koniver describe using them, yet David Sinclair notes that lower growth signaling goes with longer life and Huberman lists the risks of injecting it. The contrast shows why feeling younger and living longer are not always the same goal.
Reversing type 2 diabetes: what Fung, Attia and Means say works
Jason Fung calls type 2 diabetes a problem of too much sugar stored in the body, Peter Attia describes the factors behind it and cases of remission, and Casey Means explains the early blood markers. They agree the condition can often be pushed back with food timing, weight loss and movement, which changes how patients should think about a diagnosis.
Is fruit a problem? Fructose, fiber and the fatty liver question
Robert Lustig and the Means siblings single out fructose as uniquely harmful to the liver, yet Jason Fung, Peter Attia and David Sinclair each draw a different line between whole fruit, juice and added sugar. Sorting out their positions tells readers what to cut and what to keep eating.
Use it or lose it: novelty and mental challenge protect the aging brain
Tommy Wood, Mark D'Esposito, Alan Castel and Charan Ranganath all say the brain stays adaptable when it keeps meeting new and demanding tasks, and that routine alone lets it slide. This gives people a second lever against cognitive decline that works alongside exercise and sleep.
Artificial Sweeteners: Harmless Swap or Hidden Problem for Gut and Appetite?
Layne Norton treats non-sugar sweeteners as a useful way to cut calories, Robert Lustig and Justin Sonnenburg see risks to insulin and the microbiome, and Peter Attia and Andrew Huberman end up in the middle with limited use. The sources show what evidence each position leans on; gastroenterologist Chris Thompson was asked the question, but his answer did not survive in the available transcript.
