render.py --export bundles the 25 new motion rigs and info pages; figure-fixtures.json regenerated for all 47 (the Swift solver reproduces every new motion, including negative-y pins and the new prop uses). The fixture count assertion moves to 47, and the no-bundled-motion test now uses Treadmill - a permanent COVERAGE.md exclusion - since Bench Press exists. 48 tests green; watch target builds. Coverage handoff complete - TODO-coverage.md retired. Claude-Session: https://claude.ai/code/session_01HJDQQDA9QdP8zByg43H5v3

# Push-Up
|
||
|
||
The bodyweight press — a moving plank: lower the chest to the floor and
|
||
press back up without the hips sagging.
|
||
|
||
- **Category:** Warm-up and main circuit
|
||
- **Type:** Bodyweight horizontal press
|
||
- **Targets:** Chest, front delts, triceps, trunk
|
||
- **Prescription:** 3 × 8–15
|
||
|
||
## Setup
|
||
|
||
Hands under the shoulders, legs long, toes tucked. Squeeze the glutes
|
||
and brace so the body is one straight line from head to heels.
|
||
|
||
## Execution
|
||
|
||
1. Bend the elbows about 45° from the body and lower the chest toward
|
||
the floor.
|
||
2. Stop a fist's height off the ground, body still one line.
|
||
3. Press the floor away to straight arms.
|
||
|
||
## Cues
|
||
|
||
- The plank never breaks — hips neither sag nor pike.
|
||
- Screw the hands into the floor to keep the elbows tracking.
|
||
- Chest leads the descent, not the chin or the hips.
|
||
|
||
## Common Mistakes
|
||
|
||
- Hips sagging into a banana shape.
|
||
- Flaring the elbows to 90°.
|
||
- Craning the neck at the floor.
|
||
|
||
## Progression
|
||
|
||
Start from an incline (hands on a bench) if reps stall; graduate to feet
|
||
elevated, then slow negatives.
