Engineering Better NFL Athletes 🐊

A few years ago, I was sitting in a closed-door meeting with some of the most elite minds in human performance on the planet. The topic: how do we actually optimize sleep for the world's highest performers? We went around the room. These were people responsible for astronauts, Tier 1 military operators, Olympic athletes, and billion-dollar executives. And the answer was the same from everyone: Consumer wearables OR a clinical sleep study in a creepy hospital. That was it. That was the ceiling. I've spent my career working with some of the most decorated athletes in history: UFC fighters, MLB All-Stars, Olympic medalists, Hall of Famers, etc. We have incredibly precise tools for just about everything for training, nutrition, recovery — but when it came to sleep, the most fundamental pillar of human performance, we were stuck choosing between a $300 tracker OR a single night wired up in a hospital so we could be told we may or may not have apnea and sent home with a CPAP machine. Both of those options share the same fatal flaw: they tell you that your sleep is bad. But THEY DON'T TELL YOU WHY - so they don't give you a real plan to fix or improve. That gap is what led me to co-found @Absolute_Rest with my partner, Josh Ruben, a neurotechnology entrepreneur who was running into the same wall while building eye-tracking diagnostic systems for NASA and the DOD. We asked ourselves a simple yet radical question: if you had an unlimited budget and wanted to build the world's most precise sleep-optimization system from scratch, what would it actually look like? Over the last five years, we've assembled an interdisciplinary team — sleep clinicians, neuroscientists, clinical psychologists, performance coaches — to build exactly that. Today, Absolute Rest combines AT-HOME & WIRELESS FDA-cleared clinical-grade hardware (as good or better than you'll find in any sleep hospital or research lab), advanced biomarker testing, environmental analysis, and world-class expert coaching into a single, end-to-end platform. What started as a bespoke program for elite athletes and executives has grown into something much bigger. We've now supported hundreds of clients from all walks of life who have one thing in common — they are done being told they're bad sleepers and ready to finally feel how sleep can go from an anchor to an advantage. I am grateful to those of you who've supported us thus far. HUGE things are coming soon with this remarkable company. absoluterest.com to learn more.


The value of daily body weight isn’t the number. It’s the conversation it creates. Not: “Why is your weight down today?” But: “I noticed your score trends are off a bit this week. What’s going on?” That shift opens the door to: - sleep - hydration - nutrition - stress - recovery Context drives better coaching. And better coaching drives availability.

Controlled sleep restriction studies consistently show the same pattern: restrict healthy adults to 4-6 hours a night, and within a week, cortisol, glucose tolerance, insulin sensitivity, muscle protein synthesis, appetite hormones, and testosterone all move in the wrong direction. No single marker tells the story. The tax is cumulative.

@MarkHoover71 @StrCoachNetwork Just to be clear: My interest on this platform is NOT to debate. I’ve rarely talked publicly about my journey/story over the last 20 years (and even downplay it), but when I share what I think are simple anecdotes with people in my circle, it typically ends up leaving a profound impact on people that I never realized. Until a few weeks ago I didn’t participate on social media, but I’ve been strongly encouraged for quite some time by friends and mentors to start sharing, so here we are! I’ll be the first to say that Jay’s system isn’t the be all end all. I’ve met a lot of people with competing ideas who are doing great work. However, I will also say that what Jay and I did together almost 30 years ago WAS revolutionary and ahead of its time. While many have heard of my story, they only really know just the tip of the iceberg. What I learned and experienced during those years could fill dozens of books with life lessons and is far more valuable than any college degree. I’m want to share these I’m still learning how to use this platform - my communication style is brutally direct and can be off putting for some, but I try to be authentic and certainly don’t want to come across in a disrespectful way. Appreciate it all! 🙏

@carvperformance @MarkHoover71 @AdamArchuleta It’s an interesting follow Schroeder remains a bit of an enigma Old PLUSA articles by him were nuts



The dangerous idea in human performance is not always doing too much. Sometimes it is doing too little meaningful chronic work, then acting surprised when the body breaks down the moment real demands show up. That is the heart of Gabbett’s training injury prevention paradox. The paper argues that athletes accustomed to higher training loads can have fewer injuries than athletes training at lower workloads, and that non contact soft tissue injuries are often tied not to training itself, but to an inappropriate training program with excessive and rapid spikes layered on top of inadequate preparation. As Gabbett put it, “reductions in workloads may not always be the best approach to protect against injury.” Three points jump out immediately: • Too little meaningful chronic work can leave athletes underprepared for the actual demands of practice and competition. • Rapid increases in load are a major problem for non contact soft tissue injury risk. • Appropriately graded high training loads can improve fitness, and that fitness may help protect against injury while improving resilience and availability. To all my fatigue mitigation specialists, we need to be careful about the resiliency we do not build through the manicure process of being “ready” or feeling good. Everybody will always feel ready to compete on the couch or doing less work. The real question is whether they are truly prepared for the demands of the activity. That is the warning in this paper. The answer is not reckless loading. It is not crushing people. It is building enough meaningful chronic exposure that hard demands are no longer novel when they matter most. Source: Gabbett TJ.
