The Coach’s Protocol — Pulling Back the Curtain
The members have spoke and I listened....Most coaches talk about principles. Some share theory. Very few show you exactly what they do themselves. about to change that. I’m opening up my personal playbook, the protocol I run on myself, to show you how I structure my training, nutrition, supplementation, peptides, and recovery strategies to stay at the top of my game. This isn’t a “one-size-fits-all” plan. It’s the real system I use, built from: - Lab data and cellular feedback loops - Peptide science and mitochondrial optimization - Periodized training matched to performance goals - Nutrition timing dialed to physiology, not fads You’ll see the exact tools, dosages, timing, and reasoning I use and how I adjust based on metrics, recovery, and results. If you’ve ever wondered how a coach integrates the science into a living, breathing system… this is your chance to see it in action. Drop a 🔥 below if you want to see the full breakdown of The Coach’s Protocol.I will likely do this as a webinar. Let me know your thoughts who would be interested in seeing this to kick off our monthly case study feature.

Sleep, Rewritten: Why Kids Sleep, Adults Don’t, and How to Restore the Signal Part 1
If you watch a child fall asleep, it looks effortless. Not because the child is relaxed or well behaved, but because nothing inside them is fighting the process. Sleep is not something the brain turns on. Sleep happens when nothing is left on. That distinction matters. Children fall asleep because their systems are quiet by default. Adults lie awake because their systems never fully stand down. Think of sleep like landing a plane. Kids approach the runway with clear airspace, working instruments, and a cooperative control tower. Adults are trying to land during a storm, with half the gauges flickering, while still answering emails from the cockpit. The issue is not motivation. It is interference. Biological coherence means all systems agree on three things at the same time. What time it is. What state the body is in. And what the priority should be. In children, these signals are aligned. Light exposure matches the sun. Food intake follows hunger. Movement happens outdoors. Stress resolves quickly. Sleep pressure builds naturally. Nothing has to be forced. In adults, those signals are fragmented. People wake before sunrise under artificial light. They eat late while stressed. They spend most of the day indoors. They carry unresolved cognitive load into the evening. They ask the brain to shut off while feeding it stimulation. Sleep does not fail because melatonin is low. Melatonin is low because the brain does not believe it is nighttime. Children do not need magnesium, glycine, mouth tape, white noise machines, or expensive mattresses because none of those fix the root problem. Children do not have chronic circadian drift. They do not live in a constant sympathetic state. Their blood sugar is more stable. Their mitochondria are more efficient. Their nervous systems are not flooded with anticipatory stress. Adults have all of these issues layered together. So adults try to override biology instead of restoring it. That is the sleep industry in one sentence. One of the biggest blind spots in sleep discussions is safety. Sleep is a vulnerable state. The brain will not enter it unless it feels safe at a biological level, not a psychological one. Children feel safe because they are not responsible for outcomes. They are not anticipating tomorrow. Stress resolves quickly in their system. Their environment is predictable. Their bodies trust the signal to let go.

Great article and couldnt agree more. I have 2 young children and I've noticed the same trends in them vs my clients, and it's a large reason why I focus so heavily with my clients on managing their nervous systems and creating a rhythm that anchors their days to help maintain that predictability for their systems day to day. Amazing results come out of dialing that in and applying that for long enough periods of time. Also, a big reason why my wife and I have night routines for our kids that include a wind down, proper light esposure/management, etc so they are set up for when they are older vs having to "unwind" years of dysfunction and dysregulation
