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

# Lunge
|
||
|
||
The split-stance squat — drop the back knee toward the floor, then drive
|
||
back up through the front heel. Bodyweight first, dumbbells in hand later.
|
||
|
||
- **Category:** Main circuit
|
||
- **Type:** Split-stance squat (bodyweight or dumbbells)
|
||
- **Targets:** Quadriceps, glutes, balance
|
||
- **Prescription:** 3 × 8–10 per side
|
||
|
||
## Setup
|
||
|
||
Take a long step so both knees can bend to 90° — front shin vertical,
|
||
back heel up. Hips square to the front, hands at your sides or on hips.
|
||
|
||
## Execution
|
||
|
||
1. Lower straight down until the back knee hovers just above the floor.
|
||
2. The front knee stays over the mid-foot, torso upright.
|
||
3. Drive through the front heel to come back up. Finish the set, then
|
||
switch sides.
|
||
|
||
## Cues
|
||
|
||
- Down like an elevator, not forward like a slide.
|
||
- Front heel carries the work; the back leg balances.
|
||
- Squeeze the front glute to stand up.
|
||
|
||
## Common Mistakes
|
||
|
||
- Stance too short — the front knee shoots past the toes.
|
||
- Torso pitching forward on the way up.
|
||
- Pushing off the back foot instead of the front heel.
|
||
|
||
## Progression
|
||
|
||
Hold a dumbbell in each hand; step backward into each rep (reverse lunge)
|
||
or elevate the back foot for a split squat.
