Intero · Performance, measured where it lives

Performance has a nervous system. And no one knows it better.

Load is what the world puts on you. What your body actually does with it is the part most people never see — so that's what we measure. Moment by moment, under real pressure, against your own physiology, not someone else's. Tailored and customized, from the individual to the entire organization.

The product line

Four ways in. One system underneath.

Every product reads the same Five Capacities against your own physiology — so pick the one built for you, and everything you measure travels with you.

For individuals

TERO

The gold standard in human performance.

Our coach in your pocket: an app and the Polar hardware that makes the read real. A 24/7 band builds your baseline around the clock; a chest strap gives the truth under load when it matters. A coach that has your back 24/7/365 — with an honest read of what you felt against what your body recorded.

For coaches, practitioners & clinics

CONSOLE

The one-of-a-kind actionable insights portal for client management.

The TERO companion for the people who watch over people. Every client against their own baseline, never against each other. You see what each person chooses to share; they keep everything. A roster, not a leaderboard.

For teams in high-consequence worlds

LiveLabs

The only doctrine-based scenario development and biofeedback analysis tool.

Design the scenario, run it live with real physiology streaming from every operator, then debrief on what the load actually did — person by person, moment by moment. Built for military, fire, law enforcement, and the teams whose training has to hold up under pressure.

For organizations

Integrated Solutions

Let us build exactly what you need.

The consulting and integration practice. We map the load profile your work environment actually places on your people — using the same scenario design and instrumentation that runs our platforms — and we integrate wearable technology around what you need to know, not what a brochure says a device can do.

Not sure where to start? Start with the baseline.

The 5 Capacities Baseline — the Operational Stress Reactivity Profile (OSRP) — is the free front door: one sitting, 25–35 minutes, and you walk away with your own baseline. Every product above builds on it.

Take the OSRP — free

The framework underneath

Performance isn't one thing. It's five.

The Five Capacities are five readings of the same signal: the margin between what's on you and what you've got left to carry it with. Every product above reads them the same way, so a read taken anywhere means something everywhere.

The front door · OSRP

One sitting. Your baseline across all five.

The Operational Stress Reactivity Profile is where every circle starts: a sequential protocol that puts your nervous system and your thinking under accumulating load while a chest strap records the truth beat by beat. Free, 25–35 minutes, and you leave with your own baseline.

What one sitting looks like
BASELINELOAD, ACCUMULATINGRECOVERYYOUR READ25–35 MINUTES · STRAP STREAMING BEAT-TO-BEAT THROUGHOUT
What you walk away with
  • Your five-capacity signature — threshold, variance, slope, time-under-load, recovery kinetics.
  • The read, in plain language — what the session showed, against your own physiology.
  • What you felt vs. what your body recorded — answered before any results render, so nothing anchors you.

It costs nothing but the sitting, and every product on this page builds on it: TERO reads your days against it, CONSOLE lets a coach see what you choose to share of it, LiveLabs joins it to how you perform under a live scenario. Take it once and your baseline travels with you.

What you need: a quiet half hour and a chest strap — a Polar H10, or any Bluetooth monitor that transmits beat-to-beat R-R intervals. Pairing checks the signal before you start.

Retakes at 30, 60, and 90 days are never the same session twice — and the ruler never changes, so the change you see is you.

The read, live

This is what someone looks like under load.

This is the engine behind everything we make — the same read that runs TERO, CONSOLE, LiveLabs, and the OSRP. Live physiology, read against each person's own baseline, the moment load lands visible in real time. Shown here mid-scenario.

Each event, rated for impact and IDC, against the measured response — with the operator's F3 gate beneath. Gates are calibrated to the individual, never fixed numbers.

The threshold is his — drawn from his own baseline, nobody else's. What it all stacking at once costs is the time spent under it, and how he holds there.

Recovery starts where the slope turns, not halfway up. The rate and the completeness of the return are read against his own band.

Where we stand

We'll also tell you what we don't know.

The honest position

The instrumentation is sound — research-grade heart data, quality-gated beat by beat, with the right instrument named for each job. The constructs are well-motivated in the published literature. And none of it is yet a validated instrument: the studies that would license bigger words are designed, not done. We say that plainly, because a read you can trust starts with a company that doesn't overclaim.

Two more things we hold everywhere: every number we output must sit inside the range a sports scientist or cardiologist would accept as sound, and your continuous record belongs to you — organizations only ever see what is deliberately declared or shared.

The only comparison that means anything is you.

Take the OSRP once and you have a baseline that's yours — the starting point every other circle builds on. It's free, and it takes one sitting.
