Form follows function · the two blind spots
Two structures the body's mechanics depend on. Neither one belongs to anyone.
Part I · The curriculum
Chest. Back. Shoulder. Bicep. Tricep. Quad. Hamstring. Glute. Calf. Core. The body in twelve cells. The foot is the floor of the cell.
The standard split — each cell is a training day or a section of a day
The two dashed cells are the structures whose absence the rest of Saturday demonstrates.
Part II · The care system
The systems the curriculum names. The structure the curriculum skips.
Each gets its own residency. Each gets its own department. Each gets its own billing code.
A footnote in most curricula. A specialty inside a specialty. Something you might learn in a hands-on elective.
Foot strength training is absent from the standard gym curriculum and from most hands-on movement curricula (McKeon et al., Br J Sports Med 2015;49:290).
Part III · The terminology
The formal name is six years old.
Anatomy timeline · 1858 → 2025 · six milestones
Part IV · Why this matters tonight
The two structures no one trained you to take care of.
A spring made of bone, fascia, and intrinsic muscles. The drive mechanism for every step. Sealed inside a tapered platform for sixteen hours a day. Tonight the windlass is going to lift it.
One continuous tissue from the bottom of the foot to the top of the skull. Designed to glide. Where it stops gliding, the body stops reaching. Tonight the fabric is going to be named.
The rest of the dial is what the blind spot contains.
The three tiers
Foot intrinsic muscle training is absent from standard fitness curricula. Fascia received formal anatomical recognition only in 2019. These are facts of the literature and the standards, not opinions.
Fascia is studied — by anatomists, biomechanists, and a growing research community. The statement is not that no one studies it. The statement is that the structures determining movement quality are not where most training puts its attention.
The twelve-cell curriculum here is a stylized rendering of how most commercial fitness splits look. Real programs vary. The "fascia footnote" image is a generalization about hands-on training that doesn't apply to every practitioner.
