In their own words

Huberman says he has doubled down on five foundational categories that must be re-upped every 24 hours: sleep, nutrients (macro and micro), movement, light (especially morning sunlight), and relationships.
00:05:08Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
He reversed his belief that you cannot train for endurance and strength at once; the data on concurrent training convinced him you can pursue multiple adaptations simultaneously, so he rebuilt his program to target one specific adaptation each day.
00:22:50Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
He details his full weekly split: Sunday endurance hike/jog, Monday legs, Tuesday sauna/cold plunge recovery, Wednesday cardio or torso, Thursday torso or cardio, Friday short VO2 max work, Saturday smaller muscle groups.
00:24:34Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Tibialis (tib) raises, learned from Ben Patrick (Knees Over Toes Guy), eliminated his right-side sciatica, fixed shin splints, and let him run pain-free; he also discovered he never actually had flat feet, just weak tibs.
00:33:01Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Dedicated neck training improved his posture, eye contact, confidence, and injury resilience; he does it lying on a bench and stomach with a towel-wrapped plate.
00:50:39Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
His sleep stack remains magnesium threonate, theanine, and apigenin, with added myo-inositol (900 mg) to help fall back asleep; if forced to pick two, he chooses magnesium threonate and apigenin.
01:15:41Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Rhodiola rosea (200 mg pre-workout) is his standout recent performance addition because it reduces perceived effort and post-exercise energy crash without suppressing cortisol, unlike Ashwagandha.
01:36:34Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Huberman has been monitoring sperm parameters and freezing sperm, and credits Ferriss with the idea that optimizing for fertility is a proxy for optimizing overall vitality.
01:44:32Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023

00:21:12Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
After about 25-30 minutes of repetitive exercise, central pattern generators engage so the movement becomes near-automatic, like an autopilot button appearing on the steering wheel.
00:28:43Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Protein synthesis peaks around 48 hours after a resistance workout but is held for additional days, so a muscle group does not need to be hit every 48 hours.
00:59:29Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Charles Poliquin's caution: resistance training beyond 60 minutes raises cortisol, harming sleep and recovery, so Huberman keeps lifts to an hour or less.
01:02:43Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
A University of Houston study found 'soleus pushups' (seated calf raises) done while sitting significantly improved insulin sensitivity and glucose uptake.
01:10:48Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
The soleus is about 1 percent of body musculature but can account for over 15 percent of daytime energy expenditure.
01:11:54Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023

01:18:23Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023

01:29:06Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
An Israeli study found 20 minutes of afternoon sun on bare skin three times a week significantly increased free testosterone, estrogen, and libido; the skin acts as an endocrine organ via the P53 pathway.
01:53:41Dr. Andrew Huberman · The Tim Ferriss Show · Mar 2023
Huberman recommends everyone view sunlight for two to ten minutes every morning upon waking to trigger a healthy cortisol pulse and set timers for both wakefulness and later melatonin/sleepiness.
00:16:35Andrew Huberman · The Tim Ferriss Show · Jul 2021
His preferred sleep cocktail is 50mg apigenin, 300-400mg magnesium threonate or bisglycinate, and 200-400mg theanine taken about 30 minutes before bed, paired with morning light.
00:36:20Andrew Huberman · The Tim Ferriss Show · Jul 2021

The eyes are literally two pieces of brain squeezed out during early development - the only parts of the central nervous system outside the cranial vault.
00:06:41Andrew Huberman · The Tim Ferriss Show · Jul 2021
Ideal morning light exposure is about 14 to 16 hours before you want to sleep, and your 'temperature minimum' (about two hours before natural waking) is the anchor point for shifting the circadian clock and beating jet lag.
00:24:20Andrew Huberman · The Tim Ferriss Show · Jul 2021

00:47:43Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Eccentric loading for tendons was a 'false positive' — it worked because of slow velocity, not the eccentric motion itself; heavy strength training has the identical effect, and zero velocity (isometric) gives the biggest bang for the buck.
00:22:50Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
A boot or RICE is a 'mechanical stress shielder' that removes the tension tendons need to heal, so the standard orthopedic treatment can actually make the injury worse and cause scarring.

Connective-tissue cells need only about 10 minutes of loading (e.g. 10s on, 50s off) to get the full adaptation signal, then a six-to-eight-hour refractory period before responding again — matching bone's response to as few as 40 stimuli.
00:08:19Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Tendon stress relaxation drops exponentially; by 30 seconds you reach about 85% of the bottom, and waiting two minutes only adds about 15% more — hence 30-second holds for injured tendons.
00:26:29Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Three days in a 3D-printed cast cost a mouse tendon 15–20% of its collagen and made it roughly 30% mechanically weaker — a larger loss than the muscle itself.
01:08:34Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Fluoroquinolone antibiotics like ciprofloxacin raise Achilles rupture rate about 3.5-fold, while AT-1 (angiotensin) receptor blocking 'sartan' blood-pressure drugs taken by 15+ million Americans raise it 7.6-fold.
01:19:39Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
On keto, no carbohydrate forces reliance on mitochondria, and lowered mTOR triggers 'mitophagy' that culls weak mitochondria — but keto severely harms bone mass, which is why epileptic kids must eventually cycle off it.
01:36:51Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Using a resorbable suture in Achilles repair allowed native tissue to recover and produced better collagen-synthesis markers than non-resorbable, with no difference in tendon length — contradicting surgeons' fears.
00:54:32Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Testosterone activates lysyl oxidase and decreases collagen, creating stiff but brittle tendons — explaining why steroid-using baseball players' performance would suddenly 'drop off a cliff' from tendon ruptures.
01:26:25Dr. Keith Baar · The Tim Ferriss Show · Feb 2025
Rupturing your ACL makes you 50% more likely to have a heart attack, driven by the habitual decrease in activity that follows the injury.
