Does Weight Training Count As Cardio?

Full show notes: https://bengreenfieldlife.com/504

In this solosode, you'll get the latest research on three questions I keep getting asked. First, seed oils: a brand-new randomized controlled trial put 52 adults on either a low or a typical Western intake of linoleic acid for 12 weeks, and the results are important less for what they found than for what they didn't. You'll hear why arachidonic acid didn't move, why EPA dropped instead, what that does to your inflammatory balance, which seed oils I still think are worth avoiding, and the one dietary adjustment that matters most if seed oils are part of your diet.

You'll also learn the surprisingly small amount of strength training that delivers the biggest longevity payoff, according to a 30-year study of more than 147,000 people, plus why pairing it with cardio is the single best exercise combination for blood pressure. I break down concurrent training, the interference effect between AMPK and mTOR, and when combining strength and cardio in one session helps you versus when it holds you back. Finally, I answer a listener question on peptides with six practical rules for stacking them safely, including which ones should never share a syringe, which ones cancel each other out at the receptor, and an honest look at how thin the human evidence really is behind the popular Wolverine stack.

Eat *This* If You Consume Seed Oils, Best Way To Combine Strength & Cardio, Peptide "Stacking" Rules & More! Solosode #504

Full show notes: https://bengreenfieldlife.com/juliepodcast

In this episode with Julie Gibson Clark, I'm highlighting a throwback conversation because the gap it exposed has only gotten wider. There's a leaderboard called the Rejuvenation Olympics where people submit a blood test that measures how fast they're aging. When we recorded, Julie was a 55-year-old single mom in Phoenix making under $100,000 a year, sitting at number two in the world, aging at roughly two-thirds the speed of the calendar, and ahead of people like Bryan Johnson, who was spending $2 million a year chasing the same number. Her budget was $27 a month for a gym membership and $79 a month for a supplement. This February, Bryan Johnson opened an elite longevity program at $1 million a year with three spots, an interview process, and a requirement that you hire a dedicated assistant to keep up with the protocol.

You'll learn what Julie actually does: sleep protected like it's sacred, walking and rucking, strength training and VO2 max work, a pile of vegetables every day, one supplement, prayer, and stillness. Nothing that requires an executive assistant. You'll also hear her full health history, from heavy metal toxicity and chelation therapy to the genetics that shaped her approach, exactly what she eats and when, her supplement stack, her sleep and sauna routines, and why she refuses to name a target lifespan. Now 56 and teaching as founding faculty at a longevity academy, Julie is proof that the affordable end of longevity practice still gets you remarkably far.

This 56 Year Old Mom Is Reversing Aging Faster Than Pro Biohackers On $106 A Month! With Julie Gibson Clark

Full show notes:https://bengreenfieldlife.com/dylan

In this episode with Dylan Gemelli, you'll hear one of the wildest origin stories in the health world. Dylan went from college athlete to Milan model to cocaine dealer to a 15-year prison sentence, and came out on the Fourth of July with two felonies, no job prospects, and a decision to start over. Within a year he had a million YouTube subscribers explaining compounds almost nobody was talking about yet, and today he hosts the number one health and fitness podcast in the country.

You'll also get the practical side: what SARMs really are and why he turned against steroids, what happened when a routine calcium score came back at 120 with an Lp(a) of 330, how he pushed back against the Mayo Clinic and got that number down into the 90s anyway, and what he learned about ejection fraction and chronic cardio the hard way. Dylan explains why he believes many biohackers are among the unhealthiest people out there, how stacking too many supplements and peptides creates redundancy that backfires, and which lesser-known peptides will rise in popularity.
