Muscle map

Where everything lives — the big force movers and the small, often-skipped stabilizers. Schematic, not textbook anatomy: shapes mark regions, dashed = deep muscles hidden under others.

01 / FRONT

Front view

Push movers Pull movers Core Lower body Small stabilizers Deep (hidden)
Neck (SCM) Delts Biceps Serratus anterior Forearm flexors / grip Hand intrinsics Adductors Tibialis anterior Chest (pecs) Obliques (side abs) Abs (rectus) Obliques TVA — deep brace Hip flexors Quads
Front: push movers (warm) on the chest/shoulder line, core down the middle, stabilizers threaded everywhere between. ◌ = deep, sits under the surface muscles.
02 / BACK

Back view

Neck extensors Rear delts Triceps Lats Forearm extensors QL — deep side Glute med Hamstrings Foot intrinsics Traps Rotator cuff Lats Spinal erectors Multifidus Deep hip rotators Glutes Calves
Back: the pull chain (cool) dominates — traps, lats, rear delts — with the deep stabilizers (rotator cuff, multifidus, QL) hidden underneath.
03 / THE OVERLOOKED ONES

Small stabilizers, isolated

The same two bodies with everything else faded out — so the muscles that usually get skipped are all you see. These are small, they don't move big loads, and machines do their job for you, which is exactly why they get neglected. In the base phase they're the whole point: solid outline = trainable at the surface, dashed = deep, sits under other muscle.

FRONT Neck Serratus Hand grip Adductors TVA Hip flexors Tibialis ant. BACK Neck ext. Rotator cuff Forearm ext. Glute med Deep hip rot. Lower traps Multifidus QL Foot intrinsics
The neglected roster on its own. = the ones that need a dedicated drill (compounds structurally skip them). Notice they cluster at the joints — shoulder, spine, hip, wrist, ankle — because their job is holding a joint centered while the big movers pull on it. That's why "strong-at-every-angle" is really a stabilizer story.

★ The ones that genuinely need direct work

Everything else on the map rides along on slow, full-range, unilateral compounds. These few don't — a big lift never really loads them, so they need a targeted low-load, high-control drill. Light and controlled is the point; chasing heavy load here misses it. Cool work, not warm.

  • Rotator cuff — band external rotations (shoulder health before heavy overhead)
  • Serratus anterior — wall slides, scap push-ups
  • Glute med / min — side planks, banded walks, single-leg work
  • Deep hip rotators — 90/90 hip switches, clamshells (compounds mostly miss them)
  • Tibialis anterior — tib raises (nothing else pulls the foot up under load)
  • Wrists / hands — rice bucket, wrist rocks (condition before heavy hangs)
  • Neck — light slow curls/extensions (compounds barely touch it)
  • Foot intrinsics — barefoot balance, short-foot drill

The first five are the priority; neck and feet are close behind — both are in the "mostly skipped" column of the table below. Everything not starred is already covered by doing the base-phase compounds properly.

04 / THE TABLE

Every muscle, and how it gets trained

Two routes, per the framework: indirect — the big compound done slow / full-range / no-momentum recruits the stabilizers because the task demands stability (specificity); direct — a targeted low-load control drill. Warm work builds the movers' force; cool work builds the stabilizers' control.

Pattern to notice: almost every purple row's "indirect" column is a slow, full-range, unilateral, or hanging version of a big movement. That's the base phase working as designed — the stabilizers ride along because momentum was banned. The direct drills exist for the few muscles (tibialis, neck, feet) that even good compounds skip.
