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

# Barbell Squat
|
||
|
||
The barbell back squat — bar across the upper back, sit down between the
|
||
heels, stand back up.
|
||
|
||
- **Category:** Main circuit
|
||
- **Type:** Free-weight compound squat
|
||
- **Targets:** Quadriceps, glutes, adductors, trunk
|
||
- **Prescription:** 4 × 6–8
|
||
|
||
## Setup
|
||
|
||
Set the bar on your upper traps (not the neck), hands just outside the
|
||
shoulders, and step back from the rack. Feet shoulder-width, toes slightly
|
||
out, brace before every rep.
|
||
|
||
## Execution
|
||
|
||
1. Sit down and back — hips and knees bend together, chest stays up.
|
||
2. Descend until the thighs reach at least parallel, knees tracking over
|
||
the toes.
|
||
3. Drive the floor apart and stand back up to full lockout.
|
||
|
||
## Cues
|
||
|
||
- Big breath and brace at the top; exhale at the finish.
|
||
- The bar stays over mid-foot — watch the sideways bar path, not the mirror.
|
||
- Elbows down under the bar, not flared behind it.
|
||
|
||
## Common Mistakes
|
||
|
||
- Knees caving inward out of the bottom.
|
||
- Heels lifting — weight drifting onto the toes.
|
||
- Chest collapsing forward into a good-morning.
|
||
|
||
## Progression
|
||
|
||
Master the Bodyweight Squat and Goblet Squat first; add weight in small
|
||
jumps only while depth and knee tracking hold.
