May was about forging the machine. Understanding the two cylinders that determine your long-term structural and cardiovascular durability. Building the dataset that the Engine Report will interpret.
June is about going deeper.
The Decoder early access is opening. The Engine Report is taking shape. And for anyone who wants to understand what precision longevity actually looks like in practice, there has never been a better moment to be paying attention.
If you have been measuring, you are ahead. If you have been reading but not yet acting, the gap between knowing and doing is exactly one appointment.

The Ultimate Men Over 40 Global Health Summit runs June 8โ14.
๐ฉ๐ถ๐ฟ๐๐๐ฎ๐น, ๐ณ๐ฟ๐ฒ๐ฒ ๐๐ผ ๐ฎ๐๐๐ฒ๐ป๐ฑ, and built around practitioners who show their work.
The speakers bring data and diagnostic frameworks. The content assumes you're past the point of needing motivation and ready for methodology. Seven days, seven pillars, 100+ experts covering what the second half of life actually demands from a performance and longevity standpoint.
I'm delivering two talks. "The Second Engine" is for men over 40 who want to understand how the Longevity Engine shifts after 40 and what precision-based training looks like when you stop chasing volume. "The Constraint: Men Over 40 Edition" is built for coaches and practitioners working with this population โ diagnostic methodology, pattern recognition in structural and cardiovascular data, and where the constraints compound when left unaddressed.
If you've been following this month's content, you've already seen the framework.
The Summit is where it goes deeper, with voices beyond mine adding their own diagnostic and clinical perspectives.

This month we have been building toward something: a system that takes your clinical test data and translates it into a personalized longevity roadmap.
๐ง๐ต๐ฒ ๐๐ป๐ด๐ถ๐ป๐ฒ ๐ฅ๐ฒ๐ฝ๐ผ๐ฟ๐ ๐ถ๐ ๐๐ต๐ฎ๐ ๐๐๐๐๐ฒ๐บ. It maps your DEXA, VO2 Max, RMR, Proteus Power, Movement screening, Grip Strength results through the Longevity Engine framework to produce a document that identifies your primary constraint, explains the mechanism driving it, and outlines the intervention priorities in order.
The Decoder is the tool that generates it. Early access is opening soon.
Here is what that means for you right now: every measurement you take before The Decoder launches becomes more valuable the moment it does. Your DEXA body composition data. Your VO2 Max thresholds. Your RMR baseline. The Decoder doesn't need new data. It interprets the data you already have.

This month established something important: the machine is measurable, the constraint is identifiable, and the intervention should be specific to what the data actually reveals.
The Longevity Engine Read Tool demonstrated the concept. Enter your data, see your cylinder scores, identify the primary constraint. It is a meaningful starting point built on self-reported inputs and simplified reference ranges.
The Decoder takes it the rest of the way.
It runs your clinical test data, DEXA bone density and body composition, VO2 Max with full ventilatory threshold mapping, Proteus 3D power output, RMR with metabolic flexibility analysis, through the five-cylinder Longevity Engine framework and produces a personalized Engine Report.
The Engine Report does not just score the cylinders. It explains the mechanisms driving each score. It identifies the interaction effects between systems, where the structural cylinder is limiting cardiovascular output, where metabolic inefficiency is undermining structural maintenance, where the neural cylinder is constraining power expression before the muscles show any measurable deficit. And it produces a programming priority sequence: the specific order in which constraints should be addressed for maximum return on intervention.
This is the interpretation layer at full depth.
Early access is forming now. The first cohort will be clients and practitioners with current clinical data on file. If your DEXA, VO2 Max, or Proteus assessments are more than three months old, this is the time to update them. Current data produces the most accurate Engine Report.
Testing is available at DexaFit Seattle and DexaFit Renton. If you already have recent data from another facility, it may be interpretable through The Decoder without retesting. Book a call and we will determine what you have and what you need.
