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 cleanly fuel is processed and cleared. When this capacity is constrained, every other system costs more.
Whether the body absorbs stress and returns to baseline — or accumulates it.
Whether muscle, bone, and structural reserve are being maintained across decades.
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 range it lives in, what it reveals when it moves, and the lever that actually shifts it.
