# Library Coverage Model
|
||
|
||
The picker lists exactly the bundled library names and has no free-text
|
||
fallback — the library is the app's **closed catalog**, so a missing movement
|
||
pattern or gym station is a hard wall for logging, not a cosmetic gap. This
|
||
file is the standing test for the catalog: a typical gym-goer — machine
|
||
circuit, free-weight lifter, or home/bodyweight — must be able to build their
|
||
whole program from the picker. Judge every future addition (or removal)
|
||
against both tables; the target list is their **union**.
|
||
|
||
1. **Function** — the movement-pattern × modality matrix below. A cell needs
|
||
an exercise only if real programs train that pattern that way.
|
||
2. **Equipment** — the gym-floor census below. Users log by station name, not
|
||
by pattern: Chest Press covering "horizontal push" does not cover the
|
||
flat bench. Inclusion test: *found in most commercial gyms* (Planet
|
||
Fitness / Gold's tier), not "exists somewhere."
|
||
|
||
## Pattern × modality matrix
|
||
|
||
"—" means real programs don't commonly train that pattern in that modality;
|
||
it is a considered exclusion, not a gap.
|
||
|
||
| Pattern | Machine / cable | Free weight | Bodyweight / floor |
|
||
|---|---|---|---|
|
||
| Squat | Leg Press | Barbell Squat, Goblet Squat | Bodyweight Squat |
|
||
| Hinge | Back Extension | Deadlift, Romanian Deadlift, Hip Thrust | Glute Bridge |
|
||
| Lunge | — | Lunge (dumbbells optional) | Lunge |
|
||
| Horizontal push | Chest Press, Pec Deck | Bench Press, Incline Bench Press, Dumbbell Bench Press, Dumbbell Fly | Push-Up |
|
||
| Vertical push | Shoulder Press | Dumbbell Shoulder Press | — |
|
||
| Horizontal pull | Seated Row, Face Pull | Dumbbell Row | — |
|
||
| Vertical pull | Lat Pull Down | — | Pull-Up |
|
||
| Elbow flexion | Arm Curl | Dumbbell Curl | — |
|
||
| Elbow extension | Tricep Press, Triceps Pushdown | — | Dip |
|
||
| Shoulder raise (lateral/rear) | Rear Delt Fly | Lateral Raise | — |
|
||
| Hip abduction / adduction | Abductor, Adductor | — | — |
|
||
| Calf | Calfs | — | — |
|
||
| Core anti-extension | — | — | Plank, Dead Bug, Hollow Body Hold |
|
||
| Core rotation / anti-rotation | Rotary | — | Bird Dog |
|
||
| Core lateral | — | — | Side Plank |
|
||
| Core flexion | Abdominal | — | Crunch, Reverse Crunch, Leg Raises |
|
||
| Mobility / warm-up | — | — | Cat-Cow *(morning wake-up set: next phase)* |
|
||
|
||
## Gym-floor census
|
||
|
||
Every station found in most commercial gyms, and the library entry (or
|
||
entries) a user logging by that station's name will find.
|
||
|
||
| Station | Library entries |
|
||
|---|---|
|
||
| Selectorized circuit (14 machines) | Abdominal, Abductor, Adductor, Arm Curl, Calfs, Chest Press, Lat Pull Down, Leg Curl, Leg Extension, Leg Press, Rotary, Seated Row, Shoulder Press, Tricep Press |
|
||
| Flat bench + barbell | Bench Press |
|
||
| Incline bench | Incline Bench Press |
|
||
| Squat / power rack | Barbell Squat, Deadlift, Romanian Deadlift, Hip Thrust |
|
||
| Pec deck / rear-delt fly | Pec Deck, Rear Delt Fly |
|
||
| Cable station | Triceps Pushdown, Face Pull |
|
||
| Back extension (roman chair) | Back Extension |
|
||
| Pull-up / dip station (incl. assisted machine) | Pull-Up, Dip |
|
||
| Dumbbell rack | Dumbbell Bench Press, Dumbbell Fly, Dumbbell Row, Dumbbell Shoulder Press, Dumbbell Curl, Lateral Raise, Goblet Squat, Lunge |
|
||
| Floor / mat | Bodyweight Squat, Push-Up, Crunch, Glute Bridge, Plank, Side Plank, Bird Dog, Dead Bug, Hollow Body Hold, Leg Raises, Reverse Crunch, Cat-Cow |
|
||
|
||
## Considered exclusions (the "most gyms" line)
|
||
|
||
- **Smith machine** — borderline; its uses are covered by the rack lifts and
|
||
Leg Press. Revisit if users ask.
|
||
- **Hack squat** — not universal at the Planet Fitness tier; machine squat is
|
||
covered by Leg Press.
|
||
- **Cable curl / cable crossover** — the cable station gets one entry per
|
||
pattern not already covered elsewhere; these duplicate Arm Curl / Dumbbell
|
||
Curl and Pec Deck / Dumbbell Fly.
|
||
- **Assisted dip / assisted pull-up** — folded into Dip and Pull-Up as the
|
||
regression in their Progression sections, not separate picker entries.
|
||
- **Dumbbell RDL, dumbbell lunge** — folded into Romanian Deadlift and Lunge
|
||
("barbell or dumbbells" in their pages), not separate entries.
|
||
- **Kettlebells, T-bar row, pullover machine, cardio equipment** — out; not
|
||
strength stations found in most gyms (cardio is out of the app's scope).
|
||
- **Morning wake-up mobility set** (neck rolls, arm circles, …) — deliberately
|
||
deferred to the next library phase; Cat-Cow holds the mobility row today.
|
||
|
||
## Standing exercises and `camera.zoom`
|
||
|
||
The rig is ~211 canvas units tall standing but the canvas has 152 units above
|
||
the ground line — the original 22 motions are all seated or on the floor.
|
||
Standing lifts (squats, hinges, curls, raises) author full-size anatomy and
|
||
fit the frame with the presentation-only `"camera": {"zoom": …}` transform
|
||
(see SYSTEM.md); typical values: ~0.7 standing tall, ~0.75–0.85 hanging or
|
||
seated-with-arms-overhead, 1 (omit) for lying, kneeling, seated, bent-over.
