Signals Library · Twelve markers, three capacities

Your body is already producing the signal.

Every marker on this page is a sentence your physiology is writing. Each one, read in context with the others, tells you which capacity is robust and which is constrained. This library is the reference — pick a marker to learn what it reveals and how to move it.

How every marker is scored
Fit
86 – 100
Where the healthiest people of your age and sex actually sit. Not a lab “normal” — an observed ideal.
Well
50 – 85
Inside the well range, short of Fit. Nothing diagnosable. This is where coaching does its most productive work.
Short of well
26 – 49
The clinical thresholds live here — a score of exactly 25 is the diagnosable line, at any age.
Sick
25 and under
Past the diagnosable line. Still coachable, and worth a physician’s eyes alongside the coaching.

The figures beside each marker below are the Fit edge at age 40. Your Radar shifts these bands by age and sex, so every marker page carries a calculator that scores your own number exactly the way your report does.

Capacity 01
Regulate Energy

How cleanly fuel is processed and cleared. When this capacity is constrained, every other system costs more.

HbA1c
≤ 5.2%
Three-month average of glycemic exposure. The slow, accumulating record of how well fuel is being handled.
Fasting Insulin
≤ 5 µIU/mL
How much insulin you need at rest. Elevated values reveal insulin resistance before A1c moves.
TG : HDL Ratio
≤ 1.00 (M) · ≤ 0.85 (W)
A proxy for insulin resistance and lipoprotein particle size. The Radar puts the diagnosable line at 3.5.
ApoB
≤ 76 mg/dL (M) · ≤ 73 (W)
The true count of atherogenic particles in your blood — a more accurate risk signal than LDL-C alone.
Capacity 02
Recover From Stress

Whether the body absorbs stress and returns to baseline — or accumulates it.

Blood Pressure
MAP ≤ 85.6
Scored as MAP = (SBP + 2×DBP) ÷ 3. Chronic elevation is the body failing to return to baseline.
Resting Heart Rate
≤ 58 bpm (M) · ≤ 61 (W)
Measured upon waking. A trend upward from your own baseline is the earliest recovery signal.
hs-CRP
≤ 0.67 mg/L (M) · ≤ 0.97 (W)
High-sensitivity inflammation marker. Persistent elevation means the body is not resolving stress.
ALMI
≥ 9.1 kg/m² (M) · ≥ 7.6 (W)
Appendicular lean mass index. The lean-tissue reserve that absorbs training stress and rebuilds between doses.
Capacity 03
Preserve Functionality

Whether bone, strength, and structural reserve are being maintained across decades.

Visceral Fat (VAT)
≤ 1.4 lb (M) · ≤ 1.2 (W)
Metabolically active fat around the organs. Entered in lb, scored in kg — the depot that quietly erodes long-term reserve.
BMD / T-score
T-score ≥ +0.3
Bone mineral density. Below −1.0 is low bone mass; below −2.5 is osteoporosis.
Grip Strength
≥ 52 kg (M) · ≥ 35.5 (W)
Whole-body strength proxy. Strongly predicts all-cause mortality independent of other factors.
Body Fat %
≤ 16% (M) · ≤ 23% (W)
Composition matters more than weight — and the Radar reads it on age- and sex-adjusted bands, not one cutoff.
How to use this library

Read the capacity, not the marker.

No single number tells the story. The question is always: which capacity is constrained, and where should coaching start? Each marker page shows the marker in its capacity context, the four bands it lives in, what it reveals when it moves, the lever that actually shifts it — and a calculator that scores your own number the way your Radar does.
