Skye sat on the idea of posting his workouts for three months because he knew that the second he hit publish, there was no going back.

Skye Mackintosh is the Daily Reps guy, and he's spent the past year proving you don't need a gym, a trainer, or hours a day to get in real shape. He started with pushups and jump squats. Nothing else.

What drew me in was his reason for posting. He didn't do it to build a brand. He did it because he knew that if strangers were watching, he'd finally have to follow through.

We get into the moment his ego took a hit strapping on a weighted vest, why he just told his job of nine years he's done, and how consistency actually works when you're sick, tired, or having a bad day.

There's a real conversation in here about people outsourcing their thinking to AI, why authenticity is becoming the rarest thing online, and how being bored around a campfire might be more valuable than any productivity hack. He also gets into fatherhood, marriage, and the standards he reads to himself every morning.

If you've ever felt intimidated by fitness content or told yourself you don't have time, this one will hit differently.

The sun is not as damaging as you've been told… Zaid Dahhaj shows us where the research breaks.

Zaid runs The Circadian Classroom and studies circadian biology from first principles, which is how he ended up pulling apart the mainstream narrative around melanin, melanoma, and sunscreen.

Once you understand that the research demonising UV is largely built on isolated UV exposure, nocturnal mice, albino mice, and keratinocyte-only petri dishes, the whole "sun causes cancer" story starts to look a lot less airtight.

Melanin gets reframed here as an active defence system rather than damage on a ledger. It's photoprotective, it dissipates UV as heat, and it even chelates certain heavy metals.

Night shift work is classified as a probable carcinogen, and most people are living a low-grade version of it: dark days indoors, and bright nights under LEDs. That's the inversion Zaid keeps coming back to.

We also take a serious look at sunscreen chemistry, vitamin D3, sunglasses and eye health, seed oils and burn risk, and how to build a solar callus without frying yourself on a beach in Costa Rica.

You’ll learn:

[0:00] Introduction

[8:05] Night shift work's carcinogen classification and what it reveals about us all

[11:21] Circadian repair restores UV-damaged cells so there's no accumulated damage

[20:41] The sun-cancer research is built on nocturnal mice and isolated UV

[30:34] The melanoma overdiagnosis problem and dermatology's stage zero caution

[34:26] A tan isn't damage, melanin works as nature's sunscreen

[47:16] The case for actively seeking the sun, and when to do it

[51:58] Sunglasses remove one leg of the circadian stool

[58:46] SPF 50 blocks the very anti-cancer vitamin D your skin needs

[1:09:26] The exact daily routine to build your solar callus without burning

Miesha Tate spent her whole life chasing a UFC world title, and when she won it, it broke her.

Miesha is a former UFC Women's Bantamweight Champion, one of the fighters who cracked women's MMA open at the highest level, and someone who has now spent almost as much time deconstructing what that pursuit cost her as she did chasing it.

We sat down in Malibu and got into the parts of the story you don't usually hear. The moment she realised the gold belt didn't solve a single one of her problems. The years of eating disorders, distilled water weight cuts, and amenorrhea she was privately navigating while headlining pay-per-views. The pregnancy loss earlier this year that forced her to look at what her fighting career had done to her hormones. And the coach whose death became the reason she started her podcast.

Miesha is direct about what she got wrong: the war she waged with her own body, the intuition she overrode because she'd signed on the dotted line, and the mental health cost of being the "strong woman" everyone pointed to. She's also honest about what actually helped her rebuild, from cognitive behavioural therapy to prayer to learning, for the first time in her life, how to be present.

If you've ever confused discipline with self-punishment, this one will resonate.

You’ll learn:

[0:00] Introduction

[9:53] 99% of a cage fight happens inside your own head before the walk out

[15:20] How winning the belt became the biggest breaking point of Miesha’s life

[24:15] The eating disorder, the weight cuts, and drinking distilled water for 72 hours

[40:09] Women need 100 to 300 more calories in the luteal phase, and no diet accounts for it

[52:36] The pregnancy loss she believes was tied to years of under-fueling her body

[1:04:19] How prayer, reconnection, and a cognitive behavioral therapist pulled her out of the darkness

[1:14:40] The balloon exercise that taught her presence for the first time in her life

[1:25:57] Why Miesha believes public school was designed to divide the nuclear family

Most people think big wave surfers are fearless. Luca says fear is the only place courage can exist.

Luca Padua is a big wave surfer from Half Moon Bay, California, who grew up two miles from Mavericks, one of the most dangerous waves on Earth. He surfed it for the first time at 13, lived with Laird Hamilton and Gabby Reece for six years, and now runs Bigger Than Waves, a project supporting veteran mental health through VETS.

What surprised me is how honest Luca is about being scared. He was the cautious kid his mom had to walk down the high dive.

He argues fear is intelligence, not weakness. Courage isn't innate; it's built through training, like the pool sessions with Laird that once made him black out. That framing runs through every story he tells, from his first drop at Mavericks with the jagged Boneyard rocks below him to sitting shoulder to shoulder with his childhood heroes in the lineup.

We also get into his path away from enlisting in the military, the letter from a special operations friend that changed his direction, and why he believes purpose has to come before performance.

You’ll learn:

[0:00] Introduction

[6:04] Big wave surfers aren't fearless, and the only place courage can exist

[10:33] The lore of Mavericks and what makes an 80-foot wave so deadly

[23:49] Luca’s fallout with his parents after that first Mavericks session, and finding his path forward

[37:16] The lesson Laird Hamilton taught him about being faithful in the small things

[42:01] Almost enlisting in the military, and how Bigger Than Waves and VETS was born

[53:48] What training with Ido Portal and Christian McCaffrey taught him about being a beginner

Psychedelics can expand your consciousness in a way most people can’t imagine.

My guest is Dr. Chloe West, a PhD neuroscientist who's been researching psychedelics for nearly a decade and is now writing a book on psychedelics and religious trauma.

Dr. Chloe explains what happens in the brain during a trip, from increased entropy to disorganized activity in the default mode network. Her framing of the brain as clay, where plasticity softens it, and the trip itself guides how it gets reshaped, is one of the clearest explanations I've heard.

We get into the REBUS model and one finding that stopped me: the research doesn't actually show that psychedelics reliably turn atheists into believers, even though people will swear otherwise. Beliefs about the self, however, are another story.

Her personal story is where this conversation deepens. Chloe grew up in evangelical Christianity in the South, walked away from it in graduate school, and is now researching how psychedelics might offer something the deconstruction space has been missing: a tool for reconstruction.

She describes someone close to her who spent years praying out of fear, and after psychedelics only wanted to pray out of gratitude. That single shift, from fear to gratitude, is what many therapeutic outcomes seem to rest on.

You’ll learn:

[0:00] Introduction

[3:41] Psychedelics as the fastest method for rewiring rigid beliefs

[7:57] Defining consciousness, and whether psychedelics can really expand it

[17:30] Predictive processing turns your brain into a protection machine working against you

[23:08] Why integration matters and how set and setting predict a bad trip

[27:33] Eli Lilly's $3.8 billion DMT bet and why both political sides embrace psychedelics

[37:49] Growing up evangelical and using psychedelics to heal religious trauma

[50:21] Microdosing versus heroic doses, and the new psychedelics that skip the trip

[57:32] Finding your default state of consciousness through silent retreats and breathwork

[1:05:56] Which psychedelic calls to Chloe most, and the mystery of ayahuasca's plant intelligence
