Juliet and I just got back from Vancouver and 27 straight days of back-to-back conferences. The shift at the YPO Health Summit from two years ago was striking. The conversation has moved from mitochondrial supplements to something more basic: are you doing the fundamentals? We call this third wave fitness, and it finally feels like we are cresting into it.
Romania's football federation just introduced a Black Card for youth soccer, and it is unlike anything we have seen before. Referees can now permanently end games because of how parents and spectators are behaving. No rematch, no restart, just over. There are also silent game days where adults cannot cheer or coach at all. The whole platform is built around joy, respect, and optimism in youth sports. With Outplay finished and heading to shelves next fall, we are paying close attention.
EC Synkowski's A Good Nutrition Book dropped October 1st. We wrote the foreword to the book because her work and thinking around nutrition have been genuinely transformational for us.
And finally, the University of Liverpool just published the longest randomized trial ever run on diet drinks. The results are going to surprise you, or at least give you permission to enjoy your crispy Diet Coke in peace. We have opinions, a bedazzled can, and an unhinged passion that we can't totally explain.

What if the fitness metrics you’re obsessing over aren’t telling you what you think they are? HRV. VO2 max. Resting heart rate. Zone 2. Wearables have given us more data than ever… but do you know how to use it to inform your training?
In this episode of the Ready State Podcast, Kelly and Juliet Starrett sit down with renowned strength and conditioning coach Joel Jamieson to cut through the noise around cardiovascular fitness, recovery, and resilience. Drawing on more than 25 years of experience coaching UFC champions, Olympic athletes, special operators, and professional sports teams, Joel explains why a higher HRV isn’t always “better,” what Zone 2 training is really trying to accomplish, and why your aerobic engine matters even if endurance sports aren’t your thing.
They also explore how to balance low, moderate, and high-intensity training, practical ways to measure whether your conditioning is actually improving, and why stress outside the gym has to factor into how you train. The takeaway? Better fitness isn’t about chasing a perfect score – but about understanding what your body can handle, how well it recovers, and how to train accordingly.

This one's a first: Juliet and I are recording from different states. I'm up in Evergreen, Colorado, fresh off the Farren Summit in Boulder, where Juliet and I ended up in the same room as Robb Wolf, John Welbourn, and Andy Stumpf. Felt like CrossFit 2.0.
The American Society of Hematology just raised the diagnostic floor for ferritin from 15 to 30 ng/mL, and if you've ever been told your iron levels are fine while running on empty, this is a massive deal. Juliet shares her 30-year story here, including what finally worked.
Two landmark CTE studies dropped the same week: one out of Australia showing 61% of examined rugby league brains had CTE, and one from the US putting it at 1 in 4 NFL players. We get into what that means for families and youth athletes thinking about contact sports.
Plus a real update on Outplay, our book on youth sports performance for parents, which we are nearly ready to turn in.

What does it take to keep someone performing when their job leaves almost no room for downtime? In this episode of the Ready State Podcast, Kelly and Juliet Starrett sit down with longtime friend Dr. Drew Contreras, a retired Army physical therapist who went from supporting soldiers in combat to becoming the first full-time physical therapist embedded in the White House Medical Unit.
Drew shares what he learned caring for everyone from White House staff to Presidents Barack Obama and Joe Biden – and why the fundamentals of human performance matter even more when time is your most valuable resource. From encouraging naps during relentless work schedules to introducing walking meetings at the White House, Drew explains how small changes can help people stay functional under extraordinary pressure.
The conversation also explores the changing role of physical therapy, why PTs should be doing more than treating injuries one patient at a time, and how technology such as digital health and AI could reshape the profession.

Juliet and I have been saying yes to everything this fall. We're calling it the Fall Travel Junket, and it's stacked with events from Phoenix to Vail to Antarctica. Follow our Instagram or subscribe to The Ambush for details. And spoiler: you can join us in ANTARCTICA! For real!
We've been watching the new season of Ted Lasso, which is putting women's sports on mainstream television in a way that's hard to ignore. We get into what that means culturally, including who we'd want to see make a cameo.
Private equity is moving into youth sports with the "stay-to-play" model and it's terrible for players and parents. We dig into that, the "pay-to-play" model, what's happening at the policy level, and what parents can actually do.
We close with two Instagram trends that gave us pause: men in the longevity space calling facelifts "aesthetic wellness," and a dating site for people who didn't get the COVID vaccine.

What if the biggest breakthrough in women’s health isn’t a brand-new protocol… but learning how to better apply the fundamentals to the person in front of you?
Kelly and Juliet Starrett sit down with Dr. Abbie Smith-Ryan, professor of exercise physiology and nutrition at UNC Chapel Hill, to explore what the latest research can teach us about training, body composition, creatine, and women’s health across the lifespan. Drawing from more than 15 years in the lab – and her experience as a collegiate runner who suffered 9 stress fractures – Abbie explains how our understanding of female physiology has evolved.
They unpack how women can use body composition data without becoming ruled by the numbers, why creatine may become even more valuable as we age, whether women really need female-specific strength programs, and how to approach HIIT and recovery during perimenopause and menopause.
The takeaway? Human bodies aren’t black and white. And now that we have more tools than ever, the focus should be on finding the ones that work best for you.

Juliet and I are officially empty nesters. Both girls are launched, the bathroom is clean every morning, and we're figuring out what the next phase looks like. It rhymes with dusk bike rides, protein shakes for dinner, and a cereal bar in Marin we somehow didn't know existed until now.
We also revisited one of our longest-running household debates: women's pain tolerance. An Instagram infographic claiming childbirth equals breaking 20 bones made the rounds and reignited everything. We cover what the McGill pain scale actually says, why medical research has failed women on pain, and the full story of my eardrum, which ends with blood in the ER and a pain scale I have never quite recovered from.
From there we got into our book Outplay and the data shaping every youth sports conversation right now. The number everyone cites is that 70% of kids drop out of sport by age 13. A researcher on LinkedIn tried to find the primary source and came up empty. So did researchers at the Aspen Institute. So did everyone else. We unpack what the CDC data actually shows and why citation drift doesn't mean youth sports is fine.
The biggest chunk of this episode is something I wanted to make sure we gave real time to: what two years of running the Starrett System has actually taught us. Most people coming into the program weren't working a coherent physical practice at all. They might have been doing some weight training or riding a Peloton, but nobody was hitting all three legs of the longevity triangle: strength, conditioning, and mobility. Nobody was sprinting. And a lot of people believed that the moment they felt discomfort, they should stop.
Watching that shift has been one of the most rewarding things we've done. Member Lily gained 5.4 pounds of lean mass in eight months. Cole said he's craving training every day for the first time. The fall cohort starts September 8th. Early bird: $200 off at starrettsystem.com.

Andy Stumpf spent years navigating some of the most extreme environments imaginable as a Navy SEAL, but he says the hardest lessons he learned had nothing to do with combat. In this episode of the Ready State Podcast, Kelly and Juliet Starrett sit down with the retired SEAL Team Six operator, pilot, skydiver, and author of Drownproof to explore the mindset that helps people stay steady when life feels anything but that.
From a chaotic military skydive gone spectacularly wrong to the emotional toll of divorce, Andy shares why the ability to "chunk" overwhelming challenges into the next manageable step has become one of the most valuable skills he's ever developed. Along the way, the conversation dives into self-talk, asking for help, ownership, leadership, flow state, and why resilience isn't about being fearless – but about learning to focus on what you can control when everything else feels out of control.
Whether you're navigating a personal setback, leading a team, raising kids, or simply trying to build a more resilient mindset, this episode offers practical lessons for staying grounded, making better decisions, and keeping your head above water when the inevitable storms of life arrive.

We're back from one of the most bonkers trips of our lives. Juliet and I just finished hiking the Haute Route, the classic alpine traverse from Chamonix, France to Zermatt, Switzerland, roughly 90 miles over 10 days with our daughters Georgia and Caroline. Caroline's senior trip. Years of mental infiltration paid off.
Neither of us trained specifically for it. I spent the spring managing a torn ACL and calf. I skipped the surgery because we had this trip on the calendar, and I wasn't willing to miss it. Somewhere around day eight or nine on the trail, my knee actually started to feel better. That's the thing about movement as medicine: there's no substitute for the reps.
The trip had other highlights. We've been telling Georgia since she was three that we would someday find wild Edelweiss in the Alps. On day four, crossing one of the high passes, she spotted a patch. She actually cried. It was one of the best moments of my life.
We also dig into the news that Thorne, one of the most trusted names in supplement quality, has been acquired by Procter & Gamble for $3.8 billion, and why this deal raises real questions worth watching.
Then there's the Tour de France Femme and Kasia Niewiadoma's historic climb on Mont Ventoux: 5.3 watts per kilo for 55 minutes. We talk about the coverage problem, the naming problem, and why this race deserves far more than it's currently getting.
We close out with GLP-1 Watch: new data on cancer risk reduction, dementia, addiction disorders, and which grocery category is taking the biggest hit. Spoiler: it's chips.

Movement doesn't have to feel like punishment to improve your health. In fact, Caleb Marshall believes the secret to staying active for life has far less to do with discipline – and far more to do with joy. In this episode of the Ready State Podcast, Kelly and Juliet Starrett sit down with the creator of The Fitness Marshall to explore why fun, play, music, and community may be some of the most overlooked ingredients for long-term health.
Caleb shares how growing up feeling like he didn't fit into traditional fitness or dance spaces inspired him to build a radically inclusive movement community where people of every age, ability, body type, and experience level feel welcome. They also dive into the surprising psychology behind making fitness sustainable, why creating a judgment-free environment helps people move with more confidence, and how Caleb's devastating ACL injury reshaped his relationship with recovery, resilience, and trusting his body again.
Whether you're someone who loves the gym, avoids it altogether, or simply wants to enjoy moving again, this conversation is a powerful reminder that the best exercises are often the ones you look forward to doing.
